Research Abstract |
Innate cellular immune response to viral infection results in the activation of multiple signaling steps, ultimately regulates the expression of type-I interferons (IFNs), and a mitochondrial membrane protein, MAVS plays an important role in the pathway. In the presence study, we found that mitofusin 2 (Mfn2), a mediator of mitochondrial fusion, cooperates with MAVS, and participates in the antiviral immunity. Our results suggest that Mfn2 acts as a negative regulator for antiviral signaling, and would have a distinct function unrelated to mitochondrial dynamics.
