Class Ia molecules of human leucocyte antigen (HLA-A, -B and -C) are widely expressed and play a central role in the immune system by presenting peptides derived from the lumen of the endoplasmic reticulum. In contrast, class Ib molecules such as HLA-G serve novel functions. The distribution of HLA-G is mostly limited to foetal trophoblastic tissues and some tumour tissues. The mechanism requir...
AIMS It has been suggested that the non-classic HLA class I molecule HLA-G plays a role in autoimmune disease by protecting tissues from damage by infiltrating cytotoxic T cells. Such infiltration occurs in the thyroid of patients with Graves' disease (GD) and Hashimoto's thyroiditis (HT) and can eventually result in tissue destruction. The aim of the current study was to analyse thyroid tissue...
Aberrant human leucocyte antigen-G expression and its clinical relevance in hepatocellular carcinoma
The clinical relevance of human leucocyte antigen-G (HLA-G) has been postulated in malignancies. Hepatocellular carcinoma (HCC) is a major contributor to cancer incidence and mortality worldwide; however, potential roles of HLA-G in HCC remain unknown. In the current study, HLA-G expression in 219 primary HCC lesions and their adjacent non-tumourous samples was analysed with immunohistochemistr...
زمینه و هدف: سیستمیک لوپوس اریتماتوز (sle) یک بیماری خودایمنی است و با حضور مستقیم اتوآنتی بادی ها، در برابر آنتی ژنهای هسته ای مشخص میگردد. علت اصلی sle تاکنون ناشناخته است اما برخی از ژن هایی که در مسیرهای کلیدی شامل کمپلکس های ایمنی، انتقال سیگنال ایمنی میزبان و مسیرهای اینترفرونی فعال بوده در بیماری زایی sle نقش دارند. از آنجایی که مولکولهای hla کلاس i و ii نقش بسیار مهمی را در ارائه پپ...
Human leukocyte antigen G (HLA-G) has multiple immune regulatory functions including the induction of immune tolerance in malignancies. The roles of HLA-G have not been investigated in nasopharyngeal carcinoma (NPC). This study is aimed to evaluate the role of HLA-G as prognostic factor for NPC patients as well as its role in the immune regulation. Western assays showed high HLA-G expression in...
Human leukocyte antigen-G (HLA-G) contributes to acceptance of allografts in solid organ/tissue transplantation. Most studies have determined that soluble HLA-G isoforms are systematically detected in serum/plasma of transplanted patients with significantly fewer episodes of acute and/or chronic rejection of allogeneic tissue/organ. Current models of the interactions of HLA-G and its specific r...
BACKGROUND The human leukocyte antigen G (HLA-G) molecule exhibits limited tissue distribution, low polymorphism and alternative splicings that generate seven HLA-G isoforms. HLA-G exerts multiple immunoregulatory functions. Recent studies indicate an ectopic up-regulation in tumor cells that may favor their escape from anti-tumor immune responses. This study it is an effort to clarify the pres...
The expression of Human Leukocyte Antigen G (HLA-G) on Fetal Extravillous Trophoblast (EVT) cells during pregnancy plays an important role in preventing the fetus from rejection by suppressing the maternal immune system. Decreased expression levels of HLA-G have already shown to be associated with several complications of pregnancy such as pre-eclampsia. However, it remains largely unknown how ...
دیابت نوع یک بیماری اتوایمیون و مولتی فاکتوریال می باشد. ژن های hla- drb1 ,-dqb1 (در منطقه hla واقع اند) قویترین ارتباط را با بیماری دیابت نوع یک نشان می دهند. ما در این تحقیق الل ها، ژنوتایپ ها و هاپلوتایپ های مستعدکننده و مقاوم کننده به بیماری دیابت نوع یک از ژن های hla- drb1 ,-dqb1 و همچنین نواحی آمینواسیدی بسیار پلی مورفیک ملکول های hla- dr?1 ,-dq?1 را در 105 فرد بیمار و 100 فرد سالم بررسی ...
