OTULIN inhibits TNF. 6 / 9
| 6

reach
"OTULIN overexpression significantly suppressed the production of TNF-alpha, IL-1beta, and IL-6 in PM and N9 cells via inhibiting the nuclear translocation of NF-kappaB p65 but had no effect on the pro inflammatory cytokines secreted by un activated microglia, which directly indicates that OTULIN suppressed microglia mediated neuroinflammation by inhibiting the NF-kappaB pathway and attenuated the release of inflammatory mediators under the in vitro ischemic condition."

reach
"OTULIN deficiency increases intestinal pathology in TNF emARE mice."

reach
"Interestingly, specific loss of OTULIN in myeloid cells has been reported to cause a TNF-dependent ‘cytokine storm’ via enhanced NF-κB activity leading to autoinflammation [67] ."

reach
"Consistent with the finding that OTULIN overexpression was shown to delay NF-kappaB activation of TNF, whereas its knockdown was reported to increase the output of NF-kappaB signaling [XREF_BIBR, XREF_BIBR, XREF_BIBR], we found that OTULIN overexpression strongly depressed NF-kappaB activity and reduced the release of TNF-alpha, IL-1beta, and IL-6, which are the primary pro inflammatory cytokines that aggravate brain injury."

reach
"Overexpression of OTULIN inhibits TNF signaling (Keusekotten et al., 2013); therefore, we used a retrovirus expression system to express these mutants in OTULIN knock-out (KO) cells to evaluate its function."

"Concomitant Loss of OTULIN and CYLD Interaction with HOIP Increases M1Ubiquitination at the TNF-RSC and Enhances TNF Induced Gene Activation."
