The Fas-FasL pathway and its roles in cell death and cell survival. Fas signaling via the FADD adaptor triggers the MAPK signaling cascade, leading to NF-kB activation and cellular proliferation. Th2 cells are resistant to Fas-mediated apoptosis, as well as to the activation of NF-kB following attachment of FasL. Fas signaling is necessary for the resolution of type 2 inflammation. Nonapoptotic Fas signaling in Th2 cells further contributes to lung inflammation
