Monocyte rescue of human T cells from apoptosis is CD40/CD154 dependent.

The induction of T-cell apoptosis is regulated in part by monocytes (CD14+ cells). Human peripheral blood monocytes inhibited the spontaneous cell death of activated T cells in vitro. The inhibition of T-cell apoptosis did not require autologous monocytes. Inhibition required direct contact with monocytes and was not due to a soluble factor. Furthermore… CONTINUE READING
