Abstract/OtherAbstract:
Infectious Bursal Disease (IBD) is an acute, highly contagious and immunosuppressive avian disease caused by IBD virus (IBDV). Although IBDV-induced host cell apoptosis has been established, the underlying molecular mechanism is still unclear. We report here that IBDV VP5 is a major apoptosis-inducer in DF-1 cells by interacting with the voltage-dependent anion channel 2 (VDAC2) in the mitochondrion. We found that in DF-1 cells, VP5-induced apoptosis can be completely abolished by 4, 4' -diisothiocyanatostibene-2, 2' -disulphonic acid (DIDS), an inhibitor of VDAC. Furthermore, knockdown of VDAC2 by siRNA markedly inhibits IBDV-induced apoptosis associated with decreased caspase-9 and -3 activation and cytochrome C release, leading to increased IBDV growth in host cells. Thus, VP5-induced apoptosis during IBDV infection is mediated by interacting with VDAC2, a protein that appears to restrict viral replication via inducing cell death.
