The vesicular stomatitis virus matrix protein inhibits NF-κB activation in mouse L929 cells
چکیده انگلیسی
A previous study found that NF-κB activation is delayed in L929 cells infected with wild-type (wt) strains of VSV, while activation occurred earlier in cells infected with mutant strain T1026R1 (R1) that encodes a mutation in the cytotoxic matrix (M) protein. The integrity of the other R1 proteins is unknown; therefore our goal was to identify the viral component responsible for preventing NF-κB activation in L929 cells. We found that the M protein inhibits viral-mediated activation of NF-κB in the context of viral infection and when expressed alone via transfection, and that the M51R mutation in M abrogates this function. Addition of an IκB kinase (IKK) inhibitor blocked NF-κB activation and interferon-β mRNA expression in cells infected with viruses encoding the M51R mutation in M. These results indicate that the VSV M protein inhibits activation of NF-κB by targeting an event upstream of IKK in the canonical pathway.
