Sažetak
Gender-related differences in response to drugs of abuse, such as cocaine and morphine, have been reported both in humans and in experimental animals. Besides causing analgesia, morphine has recently been shown to exert strong immunosuppressive activity. However, no data on the influence of gender on the immunomodulatory effects of morphine or opioid peptides have been reported yet. The aim of this study was to test the influence of gender on the immunomodulatory ability of the endogenous opioid peptide [Met5]enkephalin (MENK) in mice. This was done by comparing the proliferative ability of splenic T- and B-lymphocytes 14 h after systemic (intraperitoneal ; i.p.) administration of [Met5]enkephalin (2.5, 5 or 10 mg/kg body weight). The proliferative ability of T- and B-lymphocytes was assessed by testing their in vitro response to graded concentrations of the T- and B-cell mitogens, concanavalin-A (Con-A) and lipopolysaccharide (LPS), respectively. The results obtained showed that [Met5]enkephalin, at a dose of 2.5 mg/kg, enhanced the proliferative ability of T-lymphocytes in male mice, but not in female mice. Similarly, [Met5]enkephalin, at doses of 2.5 and 5 mg/kg, enhanced the proliferative ability of splenic B-lymphocytes in male mice, whereas in female mice a decrease was observed ([Met5]enkephalin 2.5 mg/kg, LPS 10 ľg/ml). [Met5]enkephalin, at a dose of 10 mg/kg, did not affect the proliferative ability of either lymphocyte population, regardless of gender. The [Met5]enkephalin-induced stimulatory effect on both T- and B-lymphocyte proliferation was reversed by naloxone (10 mg/kg body weight), injected prior to [Met5]enkephalin, suggesting an involvement of opioid receptors. Thus, the data presented provide evidence for the gender-related response of murine splenic lymphocytes to immunomodulation by [Met5]enkephalin, administered in vivo. This finding may be relevant to the potential use of [Met5]enkephalin in adjuvant therapy for immunocompromised states, such as acquired immunodeficiency syndrome (AIDS) or malignancies.
