Thrombin: A Gas Pedal Driving Innate Immunity

Hemostasis and immunity were long considered entirely separate entities. In this issue of Immunity, Burzynski et al. (2019) find that thrombin, the key enzyme within the coagulation cascade, activates IL-1α, a central pleiotropic pro-inflammatory cytokine, to promote wound healing and platelet production following ectoderm injury.
