Interleukin-10 is known to dampen immune responses and contribute to the persistence of chronic viruses and parasites. Thomas Braciale and his colleagues show in mice that the anti-inflammatory cytokine is produced, along with proinflammatory cytokines, by effector CD4+ and CD8+ T cells during an acute virus infection of the lung, thereby helping to regulate the extent of inflammatory lung damage in response to the virus.
