Improved host defense against septic peritonitis in mice lacking MyD88 and TRIF is linked to a normal interferon response.

abstract：:CD4(+) T cell help contributes critically to DC-induced CD8(+) CTL immunity. However, precisely how these three cell populations interact and how CD4(+) T cell signals are delivered to CD8(+) T cells in vivo have been unclear. In this study, we developed a novel, two-step approach, wherein CD4(+) T cells and antigen-p...
