Curcumin-rich diet decreased TNF-α and TNFR2 mRNA in UUO rats.
Curcumin did not affect TNFR1 mRNA and increased the ratio of TNFR1/TNFR2.
TNFR1 recruits the adaptor TRADD, which binds the RIP and TNFR2 in curcumin group.
TRADD-RIP-TRAF complex activates the antiapoptotic pathway and inhibits caspase 8.
Curcumin decreased TNFR2 and increased TRAF2 to decrease the apoptotic pathway.
