RNAi was performed as explained in Methods. Germ cell corpses in one gonad arm of each animal were scored for at least 15 animals 60 h after O-Desmethyl Mebeverine acid D5 the L4 stage. N/A indicates that RNAi caused defects in germline proliferation and no cell corpses could be scored.(DOC) pgen.1003517.s008.doc (50K) GUID:?8D25029D-845F-4D3F-8EED-827646DC9BAF Abstract Clathrin and the multi-subunit adaptor protein complex AP2 are central players in clathrin-mediated endocytosis by which the cell selectively internalizes surface materials. Here, we statement the essential role of clathrin and AP2 in phagocytosis of apoptotic cells. In hermaphrodite, 131 somatic cells and about half the germ cells undergo apoptosis and the producing cell corpses are quickly removed by neighboring cells in the soma or by sheath cells encasing the germ collection. The engulfment of cell corpses is essentially controlled by two partially redundant signaling pathways that induce the cytoskeletal reorganization of engulfing cells [3]. In one pathway, the intracellular molecules CED-2/CrKII, CED-5/DOCK180, and CED-12/ELMO take action through a protein conversation cascade to induce the activation of the small GTPase CED-10/Rac1, leading to the cytoskeleton reorganization necessary for engulfment [4]C[7]. In addition, the phosphatidylserine (Ptdser) receptor PSR-1 likely binds Ptdser, an eat me signal, and acts upstream of CED-2, -5, and -12 to regulate engulfment [4]. Two other signaling modules, INA-1/integrin-SRC-1/Src and UNC-73/TRIO-MIG-2/RhoG, were also found to function through the CED-5-CED-12 motility-promoting complex to facilitate CED-10 activation for corpse engulfment [8], [9]. In addition, a non-canonical Wnt pathway consisting of the MOM-5 receptor, GSK-3 kinase and APC/APR-1 may take action through.
