The murine TRAIL receptor signals caspase-independent cell death through ceramide

Death receptors such as the 55 kDa tumor necrosis factor (TNF) receptor (TNF-R55) or Fas can initiate both apoptotic (caspase-dependent) and caspase-independent routes to programmed cell death (PCD). Here, we demonstrate for the first time that the single murine receptor for (TNF)-related apoptosis-inducing ligand (mTRAIL-R2) can induce a caspase-independent form of PCD with necrosis-like features in addition to apoptosi
