Progesterone and its metabolites 5-dihydroprogesterone and 5-3-tetrahydroprogesterone decrease LPS-induced NO release in the murine microglial cell line, BV-2.

OBJECTIVE: Microglial cells, important immunosurveillance cells in the nervous system, respond to pathogens with an increase in inducible nitric oxide synthase (iNOS) expression and nitric oxide (NO) release. Because excessive release of NO may be neurotoxic, tight regulation of nitrosative stress is required.
