Interestingly, MAVS tyrosine phosphorylation triggered by viral infection began to decrease to a level lower than the uninfected cells beyond 120 min post-infection in HEK293T and MCF-7 cells, while MAVS tyrosine phosphorylation decreased to a level similar to the uninfected cells from 60 min after VSV infection in HepG2 cells, indicating that MAVS phosphorylation kinetics are cell type specific. This evidence concerns the gene MAVS and infection.
