Antiviral Response Wound Healing and Immunity

Kristen L. Mueller

Science, AAAS, Washington, DC 20005, USA

Although wound healing and infection are often overlapping processes, whether the wound healing response modulates the immune response is not well understood. Doronin et al. (see the Perspective by Herzog and Ostrov) now show that coagulation factor X, an important component of the blood clotting cascade, helps to trigger antiviral immunity in response to adenovirus infection in mice. Factor X binds to human type C adenovirus with very high affinity. Structural analysis identified the critical binding residues between factor X and adenovirus, which, when mutated, inhibited binding. Despite being able to infect splenic macrophages in mice, transcriptional profiling of spleens from mice infected with a mutant adenovirus unable to bind to factor X revealed impaired activation of signaling cascades associated with innate immunity.
