20100158927 | ANTIBODIES, METHODS AND KITS FOR DIAGNOSING AND TREATING MELANOMA - A method of diagnosing melanoma and antibodies capable of same are disclosed. The method comprises contacting a cell of the subject with an antibody comprising an antigen recognition domain capable of binding to an MHC-I molecule being complexed with a tyrosinase peptide, wherein the antibody does not bind the MHC-I in the absence of the complexed peptide, and wherein the antibody does not bind the peptide in an absence of the MHC, under conditions which allow immunocomplex formation, wherein a presence of the immunocomplex or level thereof is indicative of the melanoma. Methods for treating melanoma and antibodies capable of same are also disclosed. Pharmaceutical compositions comprising antibodies are also disclosed. | 06-24-2010 |
20110081343 | VACCINES DIRECTED TO LANGERHANS CELLS - The present invention includes isolated anti-Langerin vaccines, methods for making and using an isolated anti-Langerin antibody or binding fragment thereof and one or more antigenic peptides at the carboxy-terminus of the isolated anti-Langerin antibody, wherein when two or more antigenic peptides are present, the peptides are separated by the one or more linker peptides that comprise at least one glycosylation site. The present invention also includes isolated vectors for the expression of the anti-Langerin antigen delivery vectors and their manufactures and use. | 04-07-2011 |
20110274653 | DENDRITIC CELL IMMUNORECEPTORS (DCIR)-MEDIATED CROSSPRIMING OF HUMAN CD8+ T CELLS - Immunostimulatory compositions and methods comprising an ITIM motif-containing DC immunoreceptor (DCIR) to mediate potent crosspresentation are described herein. The inventors evaluated human CD8+ T cell responses generated by targeting antigens to dendritic cells (DCs) through various lectin receptors. A single exposure to a low dose of anti-DCIR-antigen conjugate initiated antigen-specific CD8+ T cell immunity by all human DC subsets including ex vivo generated DCs, skin-isolated Langerhans cells and blood mDCs and pDCs. Enhanced specific CD8+ T cell responses were observed when antigens like, FluMP, MART-1, viral (HIV gag), etc. were delivered to the DCs via DCIR, compared to those induced by a free antigen, or antigen conjugated to a control mAb or delivered via DC-SIGN, another lectin receptor. Addition of Toll-like receptor (TLR) 7/8-agonist enhanced DCIR-mediated crosspresentation as well as crosspriming. Thus, antigen targeting via the human DCIR receptor allows activation of specific CD8+ T cell immunity. | 11-10-2011 |
