20140142039 | Vasoactive lntestinal Peptide Release From Microparticles - Controlled release of VIP from PLGA microparticles was accomplished and varied through use of different polymer molecular sizes, addition of solutes to the inner aqueous phase, and use of our computer model. Released VIP from microparticles appeared to be bioactive and caused DCs to produce more CCL22 than DCs treated with blank particles at 7 and 24 hours. Additionally, DCs treated with VIP microparticle releasates recruited higher percentages of FoxP3+ T-cells in in vitro chemotaxis studies.

20150079026 | Controlled Release Formulations for the Induction and Proliferation of Blood Cells - The absence of regulatory T cells (Treg) may underlie disorders including but not limited to autoimmunity, dermatitis, periodontitis and even transplant rejection. Enhancing local numbers of Treg through in situ Treg expansion or induction is contemplated herein as a treatment option for these disorders. Current methods for in vivo Treg expansion are not Treg specific and are associated with many adverse side-effects. The data presented herein provides in vitro testing of a Treg-inducing microparticle providing a predictable controlled release for combinations of cytokines and drugs (e.g., IL-2, TGF-β, and/or rapamycin) resulting in targeted Treg migration. These controlled release microparticles are also capable of inducing FoxP3+ Treg in human cells in vitro suggesting that these compositions be developed into an in vivo Treg induction and expansion therapy. | 03-19-2015 |
20150265677 | RECRUITMENT OF MENSENCHYMAL CELLS USING CONTROLLED RELEASE SYSTEMS - The present invention provides microparticles that deliver in vivo predictable release profiles of at least one chemokine to create a biomimetic chemokine concentration gradient that induces the migration of multipotent stem cells to the anatomical site of the microparticles. Various release profiles are demonstrated that depend upon the relative concentration of alginate in the chemokine-loaded microparticle. Local administration and/or intraarticular injection of the microparticles are useful in conditions such as osteoarthritis. Targeted systemic delivery of the alginate chemokine microparticles to distant anatomical sites subjected to autoimmune disease symptomology can be performed by encapsulation within liposomes having targeting ligands. Consequently, upon the creation of the appropriate chemokine gradient, multipotent stem cells will migrate to the distant anatomical site where the liposomes are attached. | 09-24-2015 |
