Anti (alpha)-DEC-205 antibodies target to the DEC-205 receptor that mediates antigen presentation to T cells by dendritic cells. To exploit these properties for immunization purposes, we conjugated the melanoma antigen tyrosinase-related protein (TRP)-2 to alphaDEC-205 antibodies and immunized mice with these conjugates together with dendritic… (More)
Coupling of ovalbumin (OVA) to anti-DEC-205 monoclonal antibody (mAb) (alphaDEC) induced the proliferation of OVA-specific T cells in vivo. Expansion was short-lived, caused by dendritic cells (DCs), and rendered T cells anergic thereafter. Phenotypic analysis revealed the induction of CD25+/CTLA-4+ T cells suppressing proliferation and interleukin-2 (IL-2)… (More)
Targeting of antigens to immature dendritic cells has been shown to result in antigen-specific T-cell tolerance in vivo. In the INS-HA/TCR-HA transgenic mouse model for type 1 diabetes, we tested the potential of the dendritic cell-specific monoclonal antibody DEC-205 conjugated to the hemagglutinin (HA) antigen (DEC-HA) to prevent disease onset. Whereas… (More)
Settling a conjecture of Shi and Zhang [ZS09], we determine the unbounded-error communication complexity of the symmetric XOR functions up to a poly-logarithmic factor. Our proof is by a simple reduction to an earlier result of Sherstov.
