Fetal tissues were collected at the respective endpoints. A separate cohort exposed through E17.5 delivered naturally; offspring received MHV68 at PND10 and were analyzed at PND17.

Transcriptomic and qPCR analyses identified sex-dependent differences at the two fetal collection endpoints in developmental, immune, and GPCR-linked signaling pathways. At E17.5, benzene exposure reduced EGR2 and increased MHC II in fetal brain myeloid\/microglia-enriched cells in both sexes.
