Glucocorticoids suppress monocyte and lymphocyte function (Th1 and Th2) more than polymorphonuclear lymphocyte function.
True or False
True, hence granulomatous diseases such as Tb are prone to exacerbation and relapse
B lymphocytes and plasma cells are not resistant to suppressive effects of glucocorticoids.
