STING^−/− brains exhibit ramified microglial morphologies and reduced IBA-1 immunostaining following TBI. 24 h after TBI, brains from STING^−/− mice displayed microglia with ramified morphologies as identified by IBA-1 staining (d) as compared to WT mice (b). IBA-1 expression was significantly reduced in the STING^−/− mice at 24 h post-TBI as quantified in (b) (n = 3 mice for each genotype and timepoint)
