Abstract
Suppressor of cytokine signaling (SOCS) proteins are key regulators of innate and adaptive immunity. Mice lacking functional SOCS4 are hypersusceptible to primary infection with influenza A virus (IAV), displaying dysregulated pro-inflammatory cytokine and chemokine production in the lungs, delayed viral clearance and impaired trafficking of influenza-specific CD8(+) T cells to the site of infection. Therefore, we postulated that SOCS4 is a critical regulator of anti-viral immunity. Unexpectedly, SOCS4 was not required for CD8(+) T-cell memory generation, nor was it required to efficiently recall those cells in response to secondary IAV infection. Wild-type or SOCS4-deficient mice primed and..
