Differential effect of glucocorticoids on the activation of monocytes and macrophages
Ontology highlight
ABSTRACT: The Glucocorticoid receptor (GR/NR3C1) is expressed in almost all immune cells. Glucocorticoids (GCs) are potent regulators of inflammation with effects mainly immunosuppressive. While, GCs have pleiotropic effects on Macrophages exhibiting complex properties with enhancing as well as suppressive effects on inflammatory processes depending on their stage of differentiation and activation, the mechanisms of GCs actions on Monocytes and Macrophages and their contribution to systemic anti-inflammatory effects remain unclear. Previously we have demonstrated that NLRP3 expression is induced by GCs in macrophages differentiated from monocytes-THP-1 but not in monocytes. These findings raise the possibility that the stage of myeloid differentiation and the cellular environment dictates the actions of GR from a pro- or anti-inflammatory perspective. Moreover, our preliminary results using the same cell line THP-1 show that the differentiation process from monocytes to macrophages also is related with the downregulation of GR induced by dex.
