title: Sympathetic control of specific and non-specific immune response.
abstract: Following antigenic stimulation with specific (alloantigen) and non-specific (sheep red blood cells (SRBC) and lipopolysaccharide (LPS] antigens the expression of beta-adrenergic receptors and the interference of immune sera IgG, on uterine smooth muscle beta-adrenoceptor-specific ligands were studied. The binding of alloimmune IgG to beta-adrenoceptors appeared to be specific, because immunization with SRBC and LPS did not induce anti-beta-adrenoceptors antibodies. On the contrary, the decrease in beta-adrenergic receptor expression was observed even with alloantigens and with the conventional antigenic challenge, suggesting that this phenomenon could be a non-specific immunoregulatory mechanism.
