Differential distribution of serotonin receptor subtypes in BNSTALG neurons: Modulation by unpredictable shock stress

► Cell type specific distribution of 5-HT receptors in BNSTALG neurons. ► 5-HT receptors and transcriptional regulators are modulated by stress. ► Stress decreased 5-HT1A mRNA and protein in the BNSTALG. ► Stress up-regulates the transcriptional repressor of the 5-HT1A gene, Deaf-1.
