Involvement of Nuclear Receptors in the Enhanced IL‐2 Production by Melatonin in Jurkat Cells

Involvement of Nuclear Receptors in the Enhanced IL‐2 Production by Melatonin in Jurkat Cells Abstract: This report shows that melatonin enhances IL‐2 production by Jurkat cells via a nuclear receptor‐mediated mechanism. Jurkat cells express nuclear (RZRα, RORα1, and RORα2) and membrane (mt1) melatonin receptors, and melatonin binds to Jurkat nuclei and membranes with the same affinity described for human peripheral blood mononuclear cells (PBMCs). Melatonin enhances IL‐2 production by Jurkat cells activated by either phytohemagglutinin (PHA) or phorbol myristate acetate (PMA). PHA activation of Jurkat cells does not change the profile of melatonin receptor expression; on the contrary, PMA activation negatively regulates the mt1 receptor. In the absence of the membrane receptor, melatonin still activates the IL‐2 production. These results show that the expression of the nuclear melatonin receptor is sufficient for melatonin to activate IL‐2 production by Jurkat cells. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Annals of the New York Academy of Sciences Wiley

Abstract

Abstract: This report shows that melatonin enhances IL‐2 production by Jurkat cells via a nuclear receptor‐mediated mechanism. Jurkat cells express nuclear (RZRα, RORα1, and RORα2) and membrane (mt1) melatonin receptors, and melatonin binds to Jurkat nuclei and membranes with the same affinity described for human peripheral blood mononuclear cells (PBMCs). Melatonin enhances IL‐2 production by Jurkat cells activated by either phytohemagglutinin (PHA) or phorbol myristate acetate (PMA). PHA activation of Jurkat cells does not change the profile of melatonin receptor expression; on the contrary, PMA activation negatively regulates the mt1 receptor. In the absence of the membrane receptor, melatonin still activates the IL‐2 production. These results show that the expression of the nuclear melatonin receptor is sufficient for melatonin to activate IL‐2 production by Jurkat cells.
