Background: Several studies have recently investigated the role of leptin, the polypeptide hormone secreted primarily by white adipose tissue, in the reproduction of rodents, humans, and domestic animals. Materials and Methods: To investigate the in vitro effect of leptin on buffalo semen quality in equilibrated and frozen thawed semen, five healthy buffalo bulls (5 ejaculates from each bull) w...

Leptin, an adipocyte-derived cytokine (adipokine), has plethora of physiological roles in the body, particularly onset puberty, reproduction and immune function animal. Leptin binds with leptin receptor (LEPR) activates different intracellular signaling pathways to activate downstream gene expression process execute its functions. The present mini-review focuses on our current understanding abo...

Acute phase C-reactive protein (CRP), raised in obesity and inflammation, is a main binding protein for leptin. It is assumed that CRP contributes to leptin confrontation by preventing leptin from crossing the blood-brain barrier (BBB). Here we defined how CRP cooperates with the BBB and whether it deters leptin from attainment CNS targets. CRP was constant in blood, but did not permeate the BB...

Introduction: Leptin, secreted from adipose tissue may have some correlation with coronary artery disease according to some reports in literature. The mean concentration of plasma leptin in patients with normal and abnormal myocardial perfusion imaging (MPI) and relation of leptin levels, independently to abnormality in MPI after correction for body mass index (BMI) was evaluated. Methods...

Leptin is secreted mainly by fat, which is involved in energy metabolism and reproduction. Leptin and itsreceptor (Ob-R) have been detected in human spermatozoa and testis, thus it can be concluded leptin involves in male physiology. The goal of this study was determination of the presence of leptin receptor mRNA in the ram testis, epididymis and spermatozoa by reverse transcription polymerase ...

Background: Leptin has been implicated in the differentiation and proliferation of hematopoietic cells. Leukemia inhibitory factor (LIF) may play an important role, along with Interleukin-6 (IL-6) and granulocyte colony stimulating factor (G- CSF), in the regulation of early hematopoietic stem cells. The aim of the study was to evaluate serum level of leptin, LIF, and IL-6 in myeloid leukemia p...

IN THIS ISSUE OF THE JOURNAL are published the first group of papers submitted to the Special Call for Papers on the subject “Peptides that Regulate Food Intake.” These nine papers (7a, 32a, 37a, 37b, 41a, 42a, 43a, 46a, 49a) illustrate both the breadth and depth of the subject. They continue the contribution made by papers published in the American Journal of Physiology-Regulatory, Integrative...

obesity is a chronic disease that shows the most serious global health problems .it relates to the body fat .obesity is caused by an imbalance between energy intake and expenditure, this balance is regulated by genetic and environmental interactions. obesity, which is a risk factor for chronic diseases, has become epidemic in the developed countries. resistance to leptin hormone is one of the m...

Abstract Background Idiopathic intracranial hypertension (IIH) is typically seen in females of childbearing period; therefore, it possible that female sex hormones have a pathogenic role IIH. Obesity considered as strong risk factor for IIH, Leptin levels the serum and CSF were found to be positively correlated with anthropological measures obesity. The leptin pathogenesis idiopathic not fully ...
