The production of cytokines by immunocompetent cells of intact mice was studied in various phases of the diurnal cycle. The ratio of produced cytokines was shown to differ in various phases of the diurnal cycle. The correlation between spontaneous production of various cytokines disappeared at 20:00, which reflects the development of physiological immunosuppression due to evening increase in physical activity of mice and corresponding changes in neuroendocrine status. Our results illustrate the existence of diurnal variations in intercellular interactions in the immune system. These data should be taken into account in the study of the mechanisms for cytokine immunoregulation and development of new schemes for cytokine immunocorrection. __________ Translated from Byulleten’ Eksperimental’noi Biologii i Meditsiny, Vol. 144, No. 10, pp. 448–451, October, 2007 |
