Background and Aims: Mucosal-associated invariant T (MAIT) cells are striking lymphocyte population in the blood and their importance in immune responses is growing fast. The current study was conducted to evaluate leptin hormone effects on MAIT cell functions. Materials and Methods: Five healthy male donors in ages of 22-30 years were selected and peripheral blood mononuclear cells (PBMCs) ...
Breast cancer is the most common cancer in women. Several risk factors such as age, family history of breast cancer, marital status, early menarche and late menopause are related to breast cancer. Obesity is also a main health problem associated with breast cancer incidence and subsequent mortality. Association between obesity and expansion of breast cancer may be due to excessive sex steroid h...

the aim of this study was to determine changes in the concentration of leptin and thyroid hormone in energyrestricted ewes and effect of leptin injection on thyroid hormone level. in the first experiment, 28 ewes were assigned to two groups(n=14). ewes were fed by a ration that provided 60% or 100% of maintenance energy requirements during 71 days. blood samples were collected and body w...
Background: Leptin, a 16-KDa peptide hormone secreted from theadipose tissue, plays an important role in the regulation of energyintake and expenditure and body weight regulation; furthermore,it has a regulatory function on the reproductive system. The aimof this study was to assess the relationship between serum leptinlevels and sex hormones in psoriatic patients and control groupand to determ...
results there was a significant increase (p < 0.05) in leptin levels on day 14 (12.75 + 5.8 ng/ml) and day 21 (12.91 + 3.2 ng/ml) for age group 18-30 years compared to day 14 (11.60 + 3.2 ng/ml) and day 21 (11.60 + 3.2 ng/ml) for age group 31-40 years. leptin was positively correlated with fsh on day 14, with lh on day 7 and day 21; likewise, with progesterone on day 21 and day 28 and with estr...

conclusions the leptin can also be used for the treatment of severe and intractable l. monocytogenes and e. coli infection. results our data demonstrates that leptin is able to induce cd11b expression on neutrophils but this induction is significantly less than l. monocytogenes. indeed, cells treated with leptin had lower amounts of apoptosis compared with untreated cells. the highest amount of...
Leptin is a 16-kD protein which is secreted from white adipocytes and, its discovery has generated enormous interest in the regulation of energy balance. Leptin has been implicated in the regulation of food intake, energy expenditure, and whole-body energy balance in animals and human. Plasma leptin levels correlate with fat storages and respond to changes in energy balance. It was initially pr...

Background: Many hormones are involved in the regulation of reproduction. Leptin hormone which is mainly secreted by adipose tissue plays an important role in energy homeostasis and reproduction. It seems that leptin is an important linkage between body metabolism and reproductive system. Moreover, it has been shown that leptin and leptin receptor express in reproductive organs of some species....
