CX3CR1 and myositis disease: Here, we explore the cellular dynamics of acute inflammation and resolution in a mouse model of RRV-induced myositis and show the relative contributions of CD11bhi Ly6Chi IM and CX3CR1+ CD11bhi Ly6Clo MP in acute inflammation and resolution, respectively, and show how modulating IM infiltration improved disease outcome by promoting a tissue repair-associated MP subset.
