Popis: The aim of this study was to examine how acute immobilization stress affects the concentrations of catecholamines in the plasma and the expression of the splenic catecholamine biosynthetic enzymes tyrosine hydroxylase (TH), dopamine-Я-hydroxylase (DBH) and phenylethanolamine N-methyltransferase (PNMT) in chronically socially isolated rats. We found that acute immobilization increases the plasma catecholamine levels and splenic PNMT protein levels in chronically socially isolated rats. These results show that acute stress of chronically stressed animals activates the sympatho-adrenomedullary system and increases synthesis of splenic PNMT by 37%, both of which can modulate the immune function.
