Biological target: LY 215840 is a potent 5-hydroxytryptamine (5-HT)2 receptor antagonist.
In vitro activity: To determine if the effects of paroxetine are mediated via modulation of the 5-HT system, this study treated macrophages with 5-HT or 5-HT receptor antagonist (LY215840) in the presence of LPS and/or paroxetine. 5-HT treatment by itself did not affect LPS-induced cytokine production. LY215840, however, reversed paroxetine's effect on LPS-induced TNFα production but not IL-6. Reference: Int Immunopharmacol. 2015 Apr;25(2):485-92. https://pubmed.ncbi.nlm.nih.gov/25744603/
In vivo activity: Serotonin (5-HT) stimulates aldosterone secretion from the rat adrenal gland through 5-HT(7) receptors. The aim of the present study was to investigate the transduction mechanisms associated with activation of 5-HT(7) receptors in rat glomerulosa cells. The stimulatory effect of 5-HT on aldosterone secretion and cAMP formation was significantly reduced by the 5-HT(7) receptor antagonist LY 215840.
