20150111766 | FLUORESCENT NEUTRALIZATION AND ADHERENCE INHIBITION ASSAYS - The present invention comprises rugged, inexpensive, reliable, and sensitive laboratory assays of antibody-based viral neutralization activity and antibody-based viral adherence inhibition activity. The assays use inactivated, fluorescently-labeled virus, allowing the tests to be performed without extensive safety precautions. The interaction of the labeled virus with target cells is monitored using flow cytometric methods. A preferred embodiment uses simple and inexpensive flow cytometry methodologies and equipment, such as bead array readers used as simplified flow cytometers. The assays are rapid, taking no longer than a few hours and are readily conducted by a trained technician. The assays are sensitive because they use labeled viruses at low concentrations and determine neutralizing and blocking capacity of sera and antibody at low concentrations. The methods are appropriate for high-throughput screening of large panels of samples. | 04-23-2015 |
20140273209 | ARTIFICIAL IMMUNE SYSTEM: METHODS OF USE - The present invention relates to methods of constructing an integrated artificial immune system that comprises appropriate in vitro cellular and tissue constructs or their equivalents to mimic the normal tissues that interact with vaccines in mammals. The artificial immune system can be used to test the efficacy of vaccine candidates in vitro and thus, is useful to accelerate vaccine development and testing drug and chemical interaction with the immune system. | 09-18-2014 |
20140248640 | METHODS FOR TESTING AN IMMUNE RESPONSE USING CULTURES OF T CELLS, B CELLS, DENDRITIC CELLS AND FOLLICULAR DENDRITIC CELLS - The present invention relates to methods for preparing an artificial immune system. The artificial immune system comprises a cell culture comprising T cells, B cells and antigen-primed dendritic cells. The artificial immune system of the present invention can be used for in vitro testing of vaccines, adjuvants, immunotherapy candidates, cosmetics, drugs, biologics and other chemicals. | 09-04-2014 |
20140147482 | ARTIFICIAL TISSUE CONSTRUCTS COMPRISING ALVEOLAR CELLS AND METHODS FOR USING THE SAME - The present invention comprises artificial tissue constructs that serve as in vitro models of mammalian lung tissue. The artificial tissue constructs of the present invention comprise functionally equivalent in vitro tissue scaffolds that enable immunophysiological function of the lung. The constructs can serve as novel platforms for the study of lung diseases (e.g., interstitial lung diseases, fibrosis, influenza, RSV) as well as smoke- and smoking-related diseases. The artificial tissue constructs of the present invention comprise the two components of alveolar tissue, epithelial and endothelial cell layers. | 05-29-2014 |

The artificial immune system can be used to test the efficacy of vaccine candidates in vitro and thus, is useful to accelerate vaccine development and testing drug and chemical interaction with the immune system. | 03-28-2013 |
20110269176 | METHODS FOR ASSAYING RESPONSES TO VACCINES - The present invention incorporates germinal centers (GCs) into three-dimensional (3D) engineered tissue constructs (ETCs). In an embodiment, we have incorporated the GC in the design of an artificial immune system (AIS) to examine immune responses to vaccines and other compounds. Development of an in vitro GC adds functionality to an AIS, in that it enables generation of an in vitro human humoral response by human B lymphocytes that is accurate and reproducible, without using human subjects. The invention also permits evaluation of, for example, vaccines, allergens, and immunogens, and activation of human B cells specific for a given antigen, which can then be used to generate human antibodies. In an embodiment of the present invention the function of the in vitro GC is enhanced by placing FDCs and other immune cells in a 3D ETC; FDCs appear more effective over a longer time (antibody production is sustained for up to about 14 days. | 11-03-2011 |
