Abstract: The present invention includes compositions and methods for increasing the effectiveness of antigen presentation using a DCIR-specific antibody or fragment thereof to which an antigen is attached that forms an antibody-antigen complex, wherein the antigen is processed and presented by a dendritic cell that has been contacted with the antibody-antigen complex.

Abstract: The present invention includes compositions and methods for making and using anti DC-ASGPR antibodies that can, e.g., activate DCs and other cells.

Abstract: Compositions and methods for targeting protein antigens to human DCs via DC-asialoglycoprotein receptor (DC-ASGPR) are disclosed herein. The DC-ASGPR carries an intracellular tyrosine-based and dileucine motif, resulting in the generation of such IL-10 Tregs both in vitro and in vivo. The methods of the present invention can be used for designing vaccines against autoimmune diseases where autoantigens are defined, such as type 1 diabetes and multiple sclerosis.

Abstract: 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.

Abstract: Nucleic acids encoding various monocyte cell proteins from a primate, reagents related thereto, including specific antibodies, and purified proteins are described. Methods of using reagents and related diagnostic kits are also provided.

Abstract: 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.

Abstract: The present invention includes compositions and methods for the expression, secretion and use of novel compositions for use as, e.g., vaccines and antigen delivery vectors, to delivery antigens to antigen presenting cells. In one embodiment, the vector is an anti-CD40 antibody, or fragments thereof, and one or more antigenic peptides linked to the anti-CD40 antibody or fragments thereof, including humanized antibodies.

Abstract: The present invention includes compositions and methods for targeting the LOX-1 receptor on immune cells and uses for the anti-LOX-1 antibodies.

Abstract: The present invention includes compositions and methods for using novel anti-CLEC-6 antibodies and fragments thereof for modulating the activity of immune cells.
