CASP8 inhibits CYLD. 13 / 17
| 10 3

reach
"We identified cFLIP upregulation that may promote caspase 8 mediated degradation of CYLD, and other necrosome components, as a possible mechanism abrogating Mtb 's capacity to coopt necroptotic signaling."

reach
"Neither RIPK1 nor RIPK3 was required for the processing of CYLD to CYLDp25 in MEFs (XREF_SUPPLEMENTARY), indicating that CASPASE 8 inactivation of CYLD occurs upstream of these necrosome components."

reach
"Neither RIPK1 nor RIPK3 were required for CYLD cleavage, and CYLD inactivation by casp8 is proposed to occur upstream of RIPK activity."

sparser
"Neither RIPK1 nor RIPK3 were required for CYLD cleavage, and CYLD inactivation by casp8 is proposed to occur upstream of RIPK activity."

reach
"In contrast, loss of CASPASE 8 prevented CYLD degradation resulting in necrotic death."

reach
"Caspase 8 then cleaves and inactivates RIPK1, RIPK3 and CYLD and stimulates apoptosis."

reach
"Caspase-8 inhibits the initiation of necroptosis by cleaving and inactivating RIP1, RIP3 [XREF_BIBR] and deubiquitinase CYLD, which was shown to be required for necroptosis induction [XREF_BIBR]."

reach
"It has recently been shown that during embryogenesis and T-cell proliferation active pro apoptotic caspase-8 blocks necroptosis by processing CYLD XREF_BIBR, XREF_BIBR, which is consistent with our findings of cross regulation of death pathways by caspase-1 activity."

reach
"Co-transfection of HEK 293 cells revealed that over-expression of wild-type CASPASE 8, but not the catalytically inactive mutant CASPASE 8-C360S, causes degradation of CYLD protein (XREF_FIG)."

reach
"Active caspase-8 has been reported to inhibit necroptosis by cleaving RIPK1, RIPK3, and CYLD XREF_BIBR - XREF_BIBR."

reach
"The apoptotic caspase-8 typically blocks necroptosis by cleaving RIPK3, CYLD, and RIPK1 [62,63,64]."

sparser
"Neither RIPK1 nor RIPK3 was required for the processing of CYLD to CYLDp25 in MEFs ( xref ), indicating that CASPASE 8 inactivation of CYLD occurs upstream of these necrosome components."

sparser
"Since caspase 8 is not recruited to the membrane-anchored TNFR-1 complex where CYLD is supposed to exert its effect [ xref , xref ], caspase 8 should not be able to cleave and inhibit CYLD at this complex."
