GPR37 and infection: However, adoptive transfer of vehicle or ARU-primed Gpr37-deficient pMΦ to WT mice (Supplementary Fig. 5b) did not show significant protective effects on mortality (P = 0.7684, Supplementary Fig. 5c) and infection rate (P > 0.05, Supplementary Fig. 5d), arguing these effects are GPR37-dependent.
