Immunology Viral Control

Chronic viral infections, like the human immunodeficiency virus and the hepatitis C virus, result in altered immune responses that help to keep the infection under control and limit virus-related pathology. Harker et al. now show that the cytokine interleukin-6 (IL-6) is required for resolving a chronic viral infection in mice. Surprisingly, IL-6 was not required during the acute stages of viral infection, but it was required once a chronic infection was established.
