Abstract

Background: Any quantity varying in the spatial-temporal dimension may be considered as a signal. Human lymphocyte cell surface molecules and subsets present circadian variation and this variation may represent a kind of signalling in the neuroendocrine-immune system. We have analyzed the dynamics of variation of specific lymphocyte subsets in healthy humans. Subjects and methods: In our study, lymphocyte subpopulation analyses were performed and cortisol, melatonin, GH and TSH serum levels were measured on blood samples collected every 4. h for 24. hours from eleven healthy men, ages 35-53 years (mean=44 ± 6 SD). Results: A clear circadian rhythm was validated for CD8 and cortisol with acrophase during the day and for CD3, CD4, melatonin, GH and TSH with acrophase at night. Cross-correlation showed that CD3 correlated positively with CD4 (ρ=0.67, P
