FIELD OF THE INVENTION

[0002] The present invention relates to novel biomarkers for mild cognitive impairment or cognitive impairment including Alzheimer disease, and methods for detecting cognitive impairment using such biomarkers.

BACKGROUND OF THE INVENTION

[0003] The commonly used means to differentiate between normal and non-normal states of a human subject using his or her biological materials are mainly those which have been used in the field of diagnostics. Most frequently used are those methods which target biomarkers in blood. It has been practiced in this field to comparatively measure the amount of a specific protein or a peptide that is less than 10,000 in molecular weight or, in the case of enzyme protein, enzyme activities in samples from normal (healthy) subjects and those from diseased individuals to help diagnosis. Here, prior to testing real samples, measurements are done on a fixed number each of samples from healthy controls and patients with certain disease with respect to the amount (s) or activity (activities) of single or multiple specific proteins or peptides and the ranges of abnormal and normal values are respectively determined. The sample to be evaluated is then analyzed by the same method and the resultant value is judged with respect to whether it is in normal or abnormal range.

[0004] In the actual measurements, the amount(s) of specified protein(s) or peptide(s) in test samples, as such or after dilution, are determined by the use of enzyme-linked immmunosorbent assay (ELISA) which uses a primary, or secondary, antibody labeled with an enzyme reacting with a substrate that yields a color upon reaction, chemiluminescent immunoassay (CLIA), radioimmunoassay (RIA) which uses a primary, or secondary, antibody labeled with a radioisotope, and, if the protein is an enzyme, the measurement of the activity of the enzyme by adding its substrate and determining the intensity of produced color, etc. These antibody-based methods are called as enzyme-, fluorescence- or radioisotope-labeled methods, respectively. In addition, there is a method where an enzyme reaction product derived from the corresponding substrate is determined by high performance liquid chromatography (HPLC). In further addition, there is a method where HPLC is combined with mass spectrometer, called LC-MS/MS, and there is a method called selected reaction monitoring (SRM)/multiple reaction monitoring (MRM) that utilizes LC-MS/MS. In another method to determine the concentration in a sample, it is appropriately pretreated, and separation of proteins or peptides is attained by 2-dimensional polyacrylamide gel electrophoresis (2D-PAGE), and target protein or peptide is determined by silver staining, Coomassie blue staining or immunological staining (Western blotting) that uses an antibody to target protein or peptide. In still further addition, there is a method which utilizes mass spectrometry to determine the amount of target protein or peptide in samples fractionated by column chromatography. Instead of column chromatography, protein chips and magnetic beads may also be utilized for purpose of pretreatment.

[0005] Furthermore, these inventors have developed an immunoMS method, where target protein or peptide is captured by beads (including magnetic ones) with linked antibody to the protein or peptide, eluted from the beads, and determined by mass spectrometry. Further, intact proteins have been reported to be analyzed by mass spectrometry using above-mentioned methods after digestion with trypsin etc. (Patent Document 1). Here, intact target proteins are selected either by fractionation or by adsorption to an adsorbant specific to them and then determined by mass spectrometry.

[0006] Number of patients suffered from cognitive impairment like Alzheimer disease is increasing rapidly along with increasing of old-age population in Japan. It is estimated that number of patients is 1.3 million in 1995 and it will be 1.9 million in 2005 and will reach to about 3.0 million in 2020. It is reported that 60-90% of cognitive impairment is Alzheimer disease. As manifestation of Alzheimer disease is not only loss of memory but several disturbance in daily life, increase of patients of this disease is becoming an important social issue to be solved. In Japan, Donepezil-hydrochloride, anti-acetylcholine esterase inhibitor has been available for medical treatment for Alzheimer disease since 1999, and it let progress of cognitive impairment in these patients be `slow-down` efficiently, if the patient is diagnosed at early stage. Thus, in medication of Alzheimer disease, most important issue is `early diagnosis` to treat the patients effectively by drug available at present and new coming drug.

[0007] Followings are major criteria for diagnosis of Alzheimer disease described in DSM-IV, which is published by American Psychiatric Association.

[0008] A. The development of multiple cognitive deficits manifested by both

[0009] (1) memory impairment (impaired ability to learn new information or to recall previously learned information)

[0010] (2) one (or more) of the following cognitive disturbances:

[0011] a) aphasia (language disturbance)

[0012] b) apraxia (impaired ability to carry out motor activities despite intact motor function)

[0013] c) agnosia (failure to recognize or identify objects despite intact sensory function)

[0014] d) disturbance in executive functioning (i.e., planning, organizing, sequencing, abstracting)

[0015] B. The cognitive deficits in Criteria A1 and A2 each cause significant impairment in social or occupational functioning and represent a significant decline from a previous level of functioning. (Non-patent reference 1)

[0016] There are several types of neurological disorders related to Alzheimer disease (AD). As cognitive dysfunction appears gradually in dementia including AD, there is a disease status of pre-stage of dementia. This stage is called as mild cognitive impairment (MCI). In United States, 10% MCI develops to AD within 1 year, and 50% of MCI develops to AD within 4 years. MCI is defined as a condition characterized by newly acquired cognitive decline to an extent that is beyond that expected for age or educational background, yet not causing significant functional impairment, and not showing disturbance in daily life. Frontotemporal dementia (frontotemporal lobar degeneration) (FTD) shows loss of personal awareness, loss of social awareness, hyperorality, and stereotyped, perseverative behavior. These clinical characteristics are different from AD. FTD includes Pick's disease, which is characterized by microscopically Pick bodies usually found in limbic, paralimbic, and ventral temporal lobe cortex. Dementia with Lewy bodies (DLB) is characterized by progressive disease and psychiatric symptoms include anxiety, depression, hallucinations (usually visual) and delusions (false beliefs). DLB is thought to be the second most common subtype and 10-30% of dementia is DLB. The symptoms of DLB are caused by the build-up of Lewy bodies. FTD and DLB belong to demented neurological disease as they also lose of memory, their ability to solve problems and maintain emotional control. (Non-patent reference 1)

[0017] In description in present patent, cognitive impairment includes AD, MCI and the demented neurological disease.

[0018] The screening tests for dementia widely used are the Hasegawa Dementia Scale-revised (HDS-R) and Mini-Mental State Examination (MMSE). In these screening tests, inspector asks several questions and evaluates level of cognitive impairment of each subject by scores. HDS-R is revised version of HDS published in 1991. In FDS-R, test consists of 9 questions to analyses orientation, remembrance, calculation, retain and recall ability, and common sense. Full score is 30 and a person whose score is less than 23 is suspected as dementia. MMSE has been developed in United States to screen and diagnose dementia, and analyses global cognitive function, with items assessing orientation, word recall, attention and calculation, language abilities, and visuospatial (drawing) ability. This test consists of 11 questions, and full score is 30 and a person who has score less than 23 is suspected as dementia. The results of HDS-R and MMSE coincide with each other. Both are used for screening, not for diagnosis and not for staging of disease progression. (Non-patent reference 1)

[0019] Neuroimaging test for dementia are Computed tomography (CT) and Magnetic resonance imaging (MRI) which evaluate morphological changes like brain atrophy and ventricular dilation and single-photon emission computed tomography (SPECT) which analyses regional cerebral blood flow and PET which shows brain metabolism by measurement of consumption of oxygen and sugar. SPECT and PET, nuclear imaging technologies, can identify neuronal dysfunction at preclinical stage. However, these neuroimaging cannot be widely used in hospitals because they need special facilities to perform nuclear imaging, and neuroimaging may not be objective test as imaging diagnosis is completely depend on the skill of physician who analyses the mages.

[0020] Thus, methods for screening and diagnosis of dementia including AD that are available at present is dependent on tests lacking objectivity and is dependent on expensive instruments, and so it is very difficult to use these tests for screening of early stage-cognitive impairment. If we get blood (serum/plasma) biomarker for cognitive impairment, which enables us objective test using specimens we can easily obtain, we can identify cognitive impairment at early stage (preclinical stage) by blood test using such biomarker. Present patent provides novel biomarkers and a novel and potent diagnostic method for cognitive impairment by using such biomarkers and biomarkers described here.

DESCRIPTION OF EMBODIMENTS

[0060] The present invention is a method for determining the kind and the amount of intact protein and/or its partial peptide when test subject is suffering from cognitive impairment as well as for diagnosing whether test subject is suffering from cognitive impairment. A peptide is generally said to be a chemical entity, made by polymerizing a number of amino acids, of less than 10,000 in molecular weight or by polymerizing several to less than about 50 amino acid residues. While in the present invention a partial peptide of an intact protein can be used as a biomarker for detection of cognitive impairment, such partial peptide is defined as a peptide of less than 10,000 in molecular weight consisting of a part of the amino acid sequence of the intact protein. Such peptide may arise as a partial peptide during the expression by transcription followed by synthesis by translation before maturing into an intact protein or as a peptide produced by enzyme digestion in the body after the intact protein has been synthesized. It is possible that, when the body is in abnormal state suffering from such disease as cognitive impairment, the mechanism for protein synthesis and regulation is de-regulated. In other words, the present invention is also a method for determining if test subject is in normal state or is suffering from cognitive impairment by using the degree of protein synthesis and/or protein digestion as an indicator. The detection of cognitive impairment in the present invention means evaluation and differentiation, i.e., diagnosis of test subject as to whether the subject is suffering from cognitive impairment. The present invention can also include the evaluation of patient's risk of suffering from more serious cognitive impairment.

[0061] Specifically, in the method of the present invention, the examples of intact protein that can be used as a cognitive impairment include Complement C3 consisting of amino acid sequence expressed by SEQ ID NO: 1, Transcription factor AP-2 gamma consisting of amino acid sequence expressed by SEQ ID NO: 3, Synapsin-3 consisting of amino acid sequence expressed by SEQ ID NO: 5, Oxytocin receptor consisting of amino acid sequence expressed by SEQ ID NO: 7, Inter-alpha-trypsin inhibitor heavy chain H5-like protein consisting of amino acid sequence expressed by SEQ ID NO: 9, E3 ubiquitin-protein ligase HERC2 consisting of amino acid sequence expressed by SEQ ID NO: 11, Prothrombin consisting of amino acid sequence expressed by SEQ ID NO: 13, Transthyretin consisting of amino acid sequence expressed by SEQ ID NO: 15, Tumor necrosis factor receptor superfamily member 16 consisting of amino acid sequence expressed by SEQ ID NO: 17, Complement C4-A consisting of amino acid sequence expressed by SEQ ID NO: 19, Complement C4-B consisting of amino acid sequence expressed by SEQ ID NO: 21, Fibrinogen alpha chain (isoform 1) consisting of amino acid sequence expressed by SEQ ID NO: 23, and Fibrinogen alpha chain (isoform 2) consisting of amino acid sequence expressed by SEQ ID NO: 25, and further, the peptide fragments that comprise of partial peptides of not less than 5 amino acid residues of these intact proteins can be used as same purpose.

[0062] Still further, an example of biomarkers for cognitive impairment of the present invention includes the partial peptides consisting of amino acid sequence expressed by SEQ ID NO: 2 of Complement C3-derived peptide CO3, SEQ ID NO: 4 of Transcription factor AP-2 gamma-derived peptide AP2C, SEQ ID NO: 6 of Synapsin-3-derived peptide SYN3, SEQ ID NO: 8 of Oxytocin receptor-derived peptide OXYR, SEQ ID NO: 10 of Inter-alpha-trypsin inhibitor heavy chain H5-like protein-derived peptide ITH5L, SEQ ID NO: 12 of E3 ubiquitin-protein ligase HERC2-derived peptide HERC2, SEQ ID NO: 14 of Prothrombin-derived peptide THRB, SEQ ID NO: 16 of Transthyretin-derived peptide TTHY, SEQ ID NO: 18 of Tumor necrosis factor receptor superfamily member 16-derived peptide TNR16, SEQ ID NO: 20 of Complement C4-derived peptide CO4-1, SEQ ID NO: 22 of Complement C4-derived peptide CO4-2, SEQ ID NO: 24 of Fibrinogen alpha chain-derived peptide FIBA-1, SEQ ID NO: 26 of Fibrinogen alpha chain-derived peptide FIBA-2, and SEQ ID NO: 27 of Fibrinogen alpha chain-derived peptide FIBA-3. In the present invention, proteins and peptides consisting of amino acid sequences derived from SEQ ID NOS: 1 through 27 by deletion, exchange, and/or addition of one or a few amino acids can be used as biomarkers and are included in the present invention. "One or a few" herein means "one or three," "one or two," or "one." Furthermore, the partial peptides that can be used as biomarkers in the present invention include those peptide fragments consisting of not less than 5 amino acid residues arising respectively from SEQ ID NOS: 1 through 27. The basis for the limitation of peptide fragments consisting of not less than 5 amino acid residues is in the description below in Non-patent Document 2. The document reported that an antibody obtained by using the peptide IRGERA as immunogen, which was the C-terminus (130-135) of histone H3, recognized the peptide IKGERA derived by exchange of K for R and the peptide CGGGERA which was derived by deletion of IR followed by addition of CGG. This demonstrates that the immunogenicity (antigenicity) is recognized by a peptide of not less than 4 amino acid residues. In order to expand this finding to other peptides than the C-terminus of histone H3, the number of amino acid residue is defined as not less than 5 instead of 4 in the present invention. To make such a low molecular weight peptide as the subject of the present invention is important when the method of detection and differentiation uses immunological means including immunoblot, ELISA and immunoMS.

[0063] It is to be noted that there are cases where a sugar chain or sugar chains have been added to an intact protein or its partial peptide to form glycated entities. Proteins and partial peptides in glycated form can also be used as biomarkers for detection of cognitive impairment.

[0064] It is also to be noted that, in the present invention, biomarker can be quantified or its presence or absence can be determined qualitatively.

[0065] Two-dimensional electrophoresis (2-DE) or 2-dimensional chromatography (2-DC) can be used in the present invention to separate biomarkers in biological materials including serum. Known chromatographic methods can be selected from ion-exchange chromatography, reverse-phase chromatography and gel-filtration chromatography. It is also possible to make quantification with the SRM/MRM method in LC-MS/MS technology. Furthermore, the immunoMS method which these inventors have developed, where target protein or peptide is captured by beads (including magnetic ones) with antibody linked to the protein or peptide, eluted from the beads, and determined by mass spectrometry enables convenient determination of presence or absence or the amount of target protein, protein fragment or peptide without the use of 2-DE or chromatography.

[0066] It is possible with the use of the method disclosed in the present invention to evaluate at the stage of mild of cognitive dysfunction in test subject and therefore it can be useful in prophylactic medicine. Further, when psychotherapy and/or drug therapy is given to patients with cognitive impairment, it is reflected in the amount of proteins and partial peptides in biological materials such as serum if the progression of the disorder has been inhibited. Therefore, by measuring these proteins and partial peptides, it is possible to evaluate and determine therapeutic effect.

[0067] The kind and amount of a protein in biological materials can be determined by various methods. If target protein (including protein fragment and partial peptide) has been characterized and when an antibody (primary antibody) to it has already been obtained, the following methods can be used:

1. Immunoblot

[0068] This is one of the simplest methods. Test serum in a fixed amount (about 1 microliter) after stepwise dilution is dropped onto an appropriate membrane such as of nitrocellulose and dried in air. The membrane is treated with a blocking solution containing a protein such as BSA, washed, reacted with primary antibody, and washed. Thereafter, the membrane is reacted with labeled secondary antibody to detect the primary antibody. The membrane is washed and the label is visualized to measure its density.

2. Western Blotting

[0069] After separation with one-dimensional or two-dimensional electrophoresis involving isoelectric focusing or SDS-PAGE, proteins are transferred onto such an appropriate membrane as of PVDF and their amounts are determined, as in above-mentioned immunoblot, using primary antibody and labeled secondary antibody.

3. ELISA

[0070] Antibody to protein or its partial peptide is fixed to such a plate as a chemically modified microtiter plate. Appropriate amounts of samples after stepwise dilution are applied to the plate and incubated. Proteins and peptides not captured are removed by washing. Next, the plate is incubated with secondary antibody labeled with fluorescent or chemiluminescent substance or enzyme. After addition of respective substrate, fluorescence, chemiluminescence or visible light due to enzyme reaction is measured for evaluation and judgment.

[0071] Additional examples of methods are illustrated below (see Patent Document 2) but the invention is not limited by these examples.

4. Methods that Use Microarray (Microchip)

[0072] A microarray is a general term for devices where solidified materials with affinity for target substances are arrayed on solid support (plate). In the present invention, antibodies or aptamer to proteins and partial peptides are arrayed. A sample of biological material is placed on the microarray for fixation of target proteins or partial peptides and the microarray is then incubated with secondary antibody labeled with fluorescent or chemiluminescent substance or enzyme. After addition of respective substrate, fluorescence, chemiluminescence or visible light due to enzyme reaction is measured.

5. Mass Spectrometry

[0073] In mass spectrometry, for example, antibody to a specified protein or partial peptide is attached to chemically modified microbeads or plate (protein chip). The microbeads could be magnetic beads. There are no requirements for the material of the plate. The antibody to be used could be (1) an antibody which recognizes the full length form of the specified protein only, (2) an antibody which recognizes a partial peptide only, (3) all of antibodies which recognizes both the specified protein and its partial peptide, or a combination of (1) and (2), (1) and (3), or (2) and (3). Samples after stepwise dilution with original solvent or buffer are added to the microbeads or plate carrying antibody or antibodies and incubated. Those proteins and partial peptides not captured are removed by washing. The protein or partial peptide captured by microbeads or plate is eluted, and analyzed by mass spectrometry with MALDI-TOF-MS, SELDI-TOF-MS, etc. Measurements are made with respect to the mass and intensity of the peak due to the protein, protein fragment or partial peptide. Prior to the measurements a fixed amount of substance serving as the internal standard is added to the original biological material and the intensity of its peak is also measured. The concentration of the target in the original biological material can be calculated from the ratio of peak intensity of the target to the peak intensity of the internal standard. This is called immunoMS method. Further, it is possible to make quantification, after the sample is diluted with original solvent or buffer, or after part of proteins are removed, by separation with HPLC followed by mass spectrometry with electrospray ionization (ESI) method. Therein the SRM/MRM method can be utilized for absolute quantification with the use of an isotope-labeled internal standard peptide.

[0074] Furthermore, in addition to the above-mentioned methods, it is possible to analyze proteins and partial peptides by using 2-DE, surface plasmon resonance, etc.

[0075] The present invention includes the method to detect cognitive impairment from the presence or absence or amount of the above-mentioned biomarker after applying biological material obtained from test subject to 2-DE or surface plasmon resonance.

EXAMPLES

[0076] Discovery of a marker peptide for detection of cognitive impairment using two-dimensional liquid chromatography-mass spectrometry (2D-LC-MALDI TOF-MS).

(1) Serum Samples.

[0077] Followings, the characters before the parenthesis are an abbreviation.

[0078] A sera obtained from 40 AD (Alzheimer's disease), 35MCI (mild cognitive impairment), 13 DLB (Dementia with Lewy bodies), 7 FTD (frontotemporal lobar degeneration), and 21 NDC (subjects not suffering from psychiatry disease) were used.

(2) Methods

[0079] After 475 μl of 0.1% trifluoroacetic acid (TFA) were added in each of 25 μl of sera, samples were boiled for 15 min at 100 degrees. Subsequently, in order to recover peptides of molecular weight of 10,000 or less, ultrafiltration were performed by using YM-10 filter unit (Millipore Corp.). Then the analysis using 2D-LC-MALDI TOF-MS were performed as follows. In other words, recovering samples were fractionated to 382 fractions per sample by using two-dimensional HPLC (SCX cation exchange column at one-dimension and C18 reverse-phase column at two-dimension). The samples were fractionated into two fractions by SCX cation exchange column, namely, SCX 1 fraction is through fraction, SCX 2 fraction is the fraction that eluted with 100% salt solution. Two fractions that were fractionated by SCX, respectively, were fractionated 191 fractions by C18 reverse phase column chromatography. It was eluted with 6 seconds in one fraction, and the retention times were calculated by multiplying the number of minus 1 from number of eluted fractions to 6 seconds. All fractionated samples were spotted on MALDI target plate (MTP AnchorChip® 600/384 plate, BRUKER DALTONICS) for MALDI TOF/TOF mass spectrometer (ultraflex TOF/TOF, BRUKER DALTONICS) using a spotting robot (AccuSpot, SHIMADZU) that is connected online, and matrix solution (alpha-cyano-hydroxycinnamic acid, CHCA) were mixed and crystallized. After mounting MALDI target plate into ultraflex TOF/TOF, the mass and the peak area of the mass were measured automatically in reflectron mode by irradiating to crystallized sample by laser. Peak area was normalized with 250 fmole of per each well of bradykinin 1-7 fragment that was added into matrix solution in advance. In other words, the area value was calculated dividing the peak area of specific mass in sample by the peak area obtained from bradykinin1-7 fragment. This area value is corresponding in 25 μl of sample serum. Detection of difference in abundance of peptides in serum between groups (called differential analysis) was performed using multi-group statistical analysis software Parnassum® (MCBI) developed by us. Peptide that was observed to difference in abundance was directly determined amino acid sequence in MS/MS analysis by ultraflex TOF/TOF, and intact proteins or peptides of their origin were identified.

(3) Results

[0080] The following shows the result of differential analysis by Parnassum software for data of serum individual subjects obtained using 2D-LC MALDI TOF-MS. FIG. 1 shows the result that was obtained from sample that was applied to 2D-LC-MALDI TOF-MS. Sample was fractionated into 2 fractions by SCX cation exchange column in the first dimension, then first fractions from SCX column (SCX 1) were fractionated into 191 fractions by C18 reverse-phase column. Mass spectra of 191 fractions were obtained by MALDI TOF-MS measuring. As the horizontal axis is the m/z and the vertical axis is the fractions of reverse-phase column chromatography, FIG. 1 was visualized by Parnassum software developed by present inventors. The dots in FIG. 1 shows respectively TOF-MS peak derived from the individual subject. The sections that dots are gathered can be regarded as the same retention time and the same m/z in the error range, and the dots in the sections are defined to be derived from the same peptide. These sections are referred to as clusters. Section (A) of FIG. 1 shows cluster of Marker A.

[0081] FIG. 2 shows the results of differential analysis in the case of Marker A. As shown in FIG. 4, Marker A is Complement C3-derived peptides CO3. FIG. 2 shows the comparison between subjects not suffering from psychiatry disease (NDC) and cognitive impairment (AD, MCI, DLB and FTD) related to CO3. In the results of t-test, area values of cognitive impairment (AD, MCI, DLB and FTD) were significantly higher than NDC (p<0.05).

[0082] From the results of FIG. 2, in order to evaluate the extent to which the Marker A is useful as biomarker, the analysis by receiver operating characteristic (ROC) curve was performed. A) and B) in FIG. 3 shows respectively the ROC curve of the comparison of AD vs. NDC and MCI vs. NDC. If the area value (hereinafter referred to as the AUC value) of under the ROC curve is close to 1, the usefulness as biomarker of Marker A will be higher. In A) and B) of FIG. 3, the typical values of sensitivity and specificity are the values of the point (open square in the figure) of the coordinate on ROC curve that the distance is minimized when a straight line was drawn to ROC curve from the point of 100% on y-axis. The value of cut-off giving this point becomes a useful threshold to distinguish between the different groups, and the values of sensitivity and specificity at that time (i.e., above the typical values) becomes an indicator of the usefulness of biomarkers together with AUC values. In A) of FIG. 3, as typical values in AD vs. NDC, the sensitivity was 73.0%, the specificity was 100%, and the AUC value was 0.88. In B) of FIG. 3, as typical values in MCI vs. NDC, the sensitivity was 70.6%, the specificity was 89.5%, and the AUC value was 0.83.

[0083] Thus, it was revealed that Marker A was useful to distinguish AD and MCI with NDC. In particular, since MCI is the state of previous stage of AD, Marker A is considered to be an extremely useful marker to detect MCI for early diagnosis of potential subjects to migrate to AD.

[0084] FIG. 4, for Marker A, illustrates the results of MS/MS spectrum using ultraflex TOF/TOF. The signals that show y-ions and b-ions have enough appeared, and the amino acid sequence could be readily identified. Mascot search was performed on this result and the protein of origin or the peptide (hereinafter referred to as intact proteins or peptides) is Complement C3, and the detected peptide was found that the sequence is APVIHQEMIGGLRN (SEQ ID NO: 2). CO3 of entry name of Swiss-Prot against Complement C3 will use as an abbreviation of the peptide name. Followings, for peptides other than CO3, entry name will use as peptide name, similarly.

[0085] Including the Marker A, the peptides that have difference in abundance between the groups in serum were measured MS/MS spectra using ultraflex TOF/TOF, and in addition to determining the amino acid sequence, the results identified intact proteins or peptides were shown below. For peptides other than Marker A, the signals that show y-ions and b-ions has enough appeared, and the amino acid sequence could be readily identified. The following amino acid sequence that shows a set of two sequences, the first sequence shows the amino acid sequence of intact proteins, and the second sequence shows the amino acid sequence of peptide detected by 2D-LC MALDI TOF-MS. The peptide comprising of the underlined portion in the first sequence correspond to the sequence of peptide detected by 2D-LC MALDI TOF-MS. The amino acid sequence starting at 0001 in the sequence shows the sequence of the N-terminus side.

(1) Complement C3-Derived Peptide CO3

[0086] CO3 shown as SEQ ID NO: 2 had formed a cluster by clustering using Parnassum software.

[0087] As shown in FIG. 2, area values of cognitive impairment (AD, MCI, DLB and FTD) were significantly higher than NDC (t-test, p<0.05). Thus, it was revealed that CO3 shown as SEQ ID NO: 2 was useful to distinguish patient of cognitive impairment (AD, MCI, DLB and FTD) with subjects not suffering from psychiatry disease (NDC). According to the analysis by receiver operating characteristic (ROC) curve, CO3 was clearly useful to distinguish AD and MCI with NDC. (See FIG. 3A), 3B) and Table 1).
