Leptin deficiency down-regulates IL-23 production in glomerular podocytes resulting in an attenuated immune response in nephrotoxic serum nephritis.

abstract：:Antigen-driven interaction of dendritic cells (DC) with CD4(+) T(h) cells results in the exchange of bidirectional activating signals. Cross-linking of TCR by MHC class II-bound antigen activates T(h) cells, resulting in their up-regulation of CD40 ligand. Here we show that MHC class II molecules, in addition to their...

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...
