Abstract
It was found that 10-min cold stress enhanced stimulated production of ROS, while 60-min cold stress increased both spontaneous and stimulated ROS production by peritoneal macrophages. β-Adrenergic receptor blockade leveled the effect of 10-min stress in stimulated cultures and the effect of 60-min stress in spontaneous cultures. None variants of cold stress affected spontaneous and stimulated production of IL-1β. We observed an increase in the production of IL-1β in stimulated cultures from animals subjected to 10- and 60-min stress against the background of propranolol. At the same time, both variants of cold exposure, irrespective of β-adrenergic receptor blockade, stimulated IL-10 synthesis in spontaneous and activated samples. None of the used models of cold exposure affected the phagocytic activity of peritoneal macrophages. Thus, β-adrenergic receptors are directly involved in the regulation of cytokine production and microbicidal potential of macrophages in acute cold stress.
