Differential susceptibility of human T(h)1 versus T(h) 2 cells to induction of anergy and apoptosis by ECDI/antigen-coupled antigen-presenting cells.

abstract：:In vaccine development, a major objective is to induce strong, specific T cell responses. This might be obtained by targeting antigen to cell surface molecules that efficiently channel the antigen into endocytic compartments for loading of MHC molecules. Antibodies have been used to deliver antigen; however, it is imp...

abstract：:The two-signal model states that activation of naive T cells requires a signal 1 stimulus through the TCR and a co-stimulatory signal 2. By contrast, signal 1 alone is sufficient for pre-activated T cells. Recently, however, it has been shown that under certain conditions T cells can bypass the requirement for co-stim...
