Circadian variation of lymphocyte subpopulations.

Aging related changes of circadian rhythmicity of cytotoxic lymphocyte subpopulations

BACKGROUND Immunosenescence is a process that affects all cell compartments of the immune system and the contribution of the immune system to healthy aging and longevity is still an open question. Lymphocyte subpopulations present different patterns of circadian variation and in the elderly alteration of circadian rhythmicity has been evidenced. The aim of our study was to analyze the dynamics ...

ALTERATION OF T-LYMPHOCYTE SUBPOPULATIONS IN SUBACUTE AND CHRONIC BRUCELLOSIS

Human brucellosis is a major health problem in developing countries. A number of patients with human brucellosis do not recover from the acute stage of the disease and pass into the chronic form. Since the pathophysiology of this change is not well understood, we studied the T-cell subsets during the acute, subacute and chronic forms of human brucellosis. In this study we found alterations...

Lymphocyte subpopulations.

Heterogeneity of Lymphocyte Subpopulations

or very minimal in all three, including cell-mediated responses in vivo; the in vitro proliferative response to mitogens, allogeneic cells, or antigens; effector cell function in lymphocyte-antibody lymphocytolytic interaction assays; and in vitro synthesis of IgG, IgA, and IgM. In contrast, mononuclear cells from one of the infants were tested and found capable of lysing both human and chicken...

Evaluation of the effects of Ramadan fasting on lymphocyte subpopulations in a two‐year follow‐up

Today, the intractions of the immune system of the immune system, nutrition, and nervous system are one of the main research areas of interest in immunology and disease treatment. Due to changes in the mood, behavior, and diet of an individual during fasting period, the body's internal homeostasis is affected. The aim of the present study was to evaluate the effects of Ramadan fasting on lympho...
