Programmed Cell Death Poster
There are two currently recognized forms of programmed cell death: apoptosis and necroptosis. This poster summarizes the signaling pathways involved in apoptosis, necroptosis and cell survival following death receptor activation, and highlights the influence of the molecular switch, cFLIP, on cell fate.
