Anti-CD3 induces bi-phasic apoptosis in murine intestinal epithelial cells: possible involvement of the Fas/Fas ligand system in different T cell compartments.

abstract：:Pathogenic intracellular bacteria often hijack macrophages for their propagation. The infected macrophages release IL-1β and IL-18 and simultaneously commit suicide, which is called pyroptosis; both responses require caspase-1. Here, we found that pyroptotic cells induced by microbial infection were efficiently engulf...
