Sex differences in cytokine production following West Nile virus infection: Implications for symptom manifestation.


ABSTRACT: West Nile virus (WNV) infection outcomes vary among individuals, with most infections resulting in asymptomatic or mild flu-like symptoms. We previously reported an association between early cytokine production and symptom outcome following WNV infection in US blood donors. In this meta-analysis, we found that WNV-infected females reported more symptoms than WNV-infected males, despite similar initial viremia and type I interferon responses. As the infection progressed, males exhibited a protracted cytokine response-marked by sustained CCL2 (MCP-1), CCL11 (eotaxin-1), CXCL10 (IP-10) and IL-15-that was absent in females. Our results suggest that sex differences may be a factor in sustaining WNV immunity.
