As reported in [30, 35], an interaction effect of ELS and ethanol drinking was found on corticosterone levels with alcohol-drinking MS360 rats displaying lower corticosterone levels compared to alcohol-drinking MS15 as well as water-drinking MS360 rats. A negative correlation was observed between Fkbp5 expression in the mPFC and corticosterone levels in alcohol-drinking MS15 rats (r s = −.943, p = .005) (Table S3).
