چکیده

To investigate the expressions of Fas and Fas ligand (FasL) in human placenta, we studied the expressions of Fas and FasL in placenta with RT-PCR, immunoblotting and immunostaining. We observed amplified products of Fas and FasL transcripts, the band of Fas (52 kDa) and multiple bands of FasL (42-52 kDa) in placenta. Fas and FasL localized mainly on fetal vessels and on syncytiotrophoblasts respectively. The differential distribution of Fas and FasL in human placenta may reflect intrinsic expressions of them by trophoblasts during differentiation. The increased expression of Fas in trophoblasts may promote apoptosis of placenta in pathologic condition such as preeclampsia.

Effect of Fas -670 A/G Gene Polymorphism on Corneal Allograft Endothelial Rejection

Background: Human cornea expresses functional Fas-ligand capable of killing Fas+ activated lymphocytes. Fas expression is partly regulated by -670 A/G polymorphism in the promoter region of Fas gene. Objective: The aim of the present study is to determine the association between Fas-670A/G polymorphism and survival of corneal transplantation. Methods: In 276 graft recipients who mainly underwen...

Aqueous 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 ...

Status of FAS and FAS Ligand Gene Polymorphisms in Patients wi th Breast Cancer in Northeastern IRAN

Background: The First apoptosis signal (FAS) and First apoptosis signal ligand (FASL) genes initiate the apoptosis pathway, playing a central role in the tumor growth and metastasis. Gene polymorphisms including -1377 G/A in the promoter region of FAS and -844 C/T in the promoter region of FASL have shown to change the transcription activities of these genes. Methods: In this study we evalua...

Activation-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...

ببررسی 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...
