Requirement for CD40 ligand in costimulation induction, T cell activation, and experimental allergic encephalomyelitis.

The mechanism of CD40 ligand (CD40L)- mediated in vivo activation of CD4(+) T cells was examined by investigation of the development of experimental allergic encephalomyelitis (EAE) in CD40L-deficient mice that carried a transgenic T cell receptor specific for myelin basic protein. These mice failed to develop EAE after priming with antigen, and CD4(+) T cells remained quiescent and produced no interferon-gamma (IFN-gamma). T cells were primed to make IFN-gamma and induce EAE by providing these mice with B7.1(+) antigen-presenting cells (APCs). Thus, CD40L is required to induce costimulatory activity on APCs for in vivo activation of CD4(+) T cells to produce IFN-gamma and to evoke autoimmunity.[1]
