abstractText | The activation of cysteine-aspartic proteases or caspases and the dynamic arrangement of cytoskeletal components are crucial during apoptosis. Here we describe the fate of Fas downstream of the FasL-induced internalization step, including formation of caspase-dependent SDS-stable Fas complexes, which is mediated by cytoskeleton integrity. We show, in particular, that following FasL treatment, the Fas lower aggregate complex can be co-immunoprecipitated with tubulin and an active form of caspase-8 and that this interaction contributes to the propagation of FasL-induced cell death. The importance of cytoskeletal components during FasL-induced apoptosis is highlighted by our detection of a pool of microtubule-associated Fas complexes. |
