Placental Fas ligand expression is a mechanism for maternal immune tolerance to the fetus.
Fas ligand (FasL) is a peptide that plays an important immunoregulatory role in limiting the host immune response. Several studies have shown that the expression of FasL in the anterior chamber of the eye and the testis allows these tissues to be immunoprivileged sites. Immunotolerance is achieved by binding of FasL to its receptor (Fas) on activated immune cells, which results in cell apoptosi...
متن کاملببررسی سطح فرم محلول FasL در مایع پریتوئن و سرم زنان مبتلا به اندومتریوز در مقایسه با زنان غیر اندومتریوز
Background: Endometriosis is a common gynecological disorder, which its main feature is the growth of endometrial tissue outside the uterine cavity. In this disease, apoptosis is impaired in endometrial cells transmitted to the peritoneal cavity, and thus these cells remain in ectopic sites and grow there. FasL-expressing cells induce apoptosis when they bind to Fas-bearing immune cells. Solubl...
متن کاملFas ligand, Fas antigen and Bcl-2 expression in human endometrium during the menstrual cycle.
In this study, we investigate Fas ligand expression in the human endometrium during the menstrual cycle in relation to Fas antigen and Bcl-2 expression, using immunoelectron microscopy and Western blotting. Endometrial samples were obtained from 54 pre-menopausal non-pregnant women who underwent laparotomies for benign diseases. The Fas ligand, as well as the Fas antigen, were expressed on the ...
متن کاملAqueous Humor Levels of Soluble Fas and Fas-ligand in Patients with Primary Open Angle and Pseudoex-foliation Glaucoma
Background: Glaucoma is one of the most common causes of blindness and is usually associated with elevated intraocular pressure. In patients with primary open angle glau-coma the number of trabecular meshwork cells is decreased. Death of the trabecular meshwork cells may be a result of apoptosis. Objective: To investigate the aqueous humor levels of soluble Fas (sFas) and Fas-Ligand (sFasL) in ...
متن کاملActivation-Induced Apoptosis in T cells: Effect of Age and Caloric Restriction
We have previously shown that the proliferative response of T cells to antigenic or mitogenic stimulus decreased with age and that caloric resection (CR) attenuated the age-related decline in proliferation and IL-2 expression. Because activation-induced apoptosis is known to regulate cell proliferation and eliminate the high number of activated cells during an immune response, it was of interes...
