Female and male microglia are not different in the dentate gyrus of postnatal day 10 mice.

ABSTRACT: Microglia, the resident immune cells of the brain, support normal brain function and the brain's response to disease and injury. The hippocampal dentate gyrus (DG) is important for microglial study due to its central role in many behavioral and cognitive functions. Interestingly, microglia and related cells are distinct in female vs. male rodents, even in early life. Indeed, postnatal day (P)-dependent sex differences in number, density, and morphology of microglia have been reported in certain hippocampal subregions at specific ages. However, sex differences in the DG have not yet been assessed at P10, a translationally relevant time point as the rodent neuroanatomical eqivalent of human term gestation. To address this knowledge gap, Iba1+ cells in the DG (which are enriched in the Hilus
