► Host factor, WFDC1/ps20 influences the innate immune response. ► WFDC1/ps20 confers protection against MHV-1 infection. ► WFDC1/ps20 regulates a neutrophil response. The whey acidic protein family member, WFDC1/ps20 is a permissivity factor in HIV infection. Herein we describe a contrasting role for ps20 in limiting MHV-1 infection. Intranasal MHV-1 infection produces a respiratory infection in mice. Using ps20 knockout mice we provide evidence that intranasal MHV-1 infection results in increased lung viral titers in ps20−/− compared to ps20+/+ mice. Accompanying MHV-1 infection we observe an increase in the number of neutrophils infiltrating the BAL and an increase in the percentage of neutrophils in the lung draining lymph nodes of ps20−/− compared with ps20+/+ mice. Gene expression levels for the neutrophil chemoattractants CXCL1 and CXCL2 are elevated in the lungs of ps20−/− mice post-MHV-1 infection. Characterization of the immune cell profile in naïve ps20−/− mice revealed an increase in circulating neutrophils compared to ps20+/+ mice. No notable differences in other immune cell profiles were observed between the ps20+/+ and ps20−/− mice. Accordingly, we examined MHV-1 infection of neutrophils and provide evidence that neutrophils isolated from ps20−/− mice are more susceptible to MHV-1 infection than neutrophils isolated from ps20+/+ mice. These data suggest roles for ps20 in regulating expression of neutrophil-specific chemotactic factors, thereby potentially modulating neutrophil migration, and in modulating neutrophil susceptibility to MHV-1 infection.
