WebIn this pathway, a Fas ligand (FasL) on the CTL binds to Fas receptor (FasR) on the target cell. This pathway is independent of granzymes. Instead it involves Interleukin-1β converting enzyme ( ICE; also known as Caspase 1) activation, which is similar to granzyme B. This ultimately leads to DNA fragmentation. References [ edit]
