Prognostic and Clinicopathological Value of Human Leukocyte Antigen G in Gastrointestinal Cancers: A Meta-Analysis

open access: yesFrontiers in Oncology, 2021
BackgroundThe prognostic value of human leukocyte antigen G (HLA-G) expression in gastrointestinal (GI) cancers remains controversial. Thus, this meta-analysis aimed to summarize available evidence from case-control or cohort studies that evaluated this ...

FREQUENCY OF OCCURRENCE OF ANTIBODIES TO HLA ANTIGENS IN RECIPIENTS ON THE WAITING LIST FOR KIDNEY TRANSPLANTATION

open access: yesМедицина в Кузбассе, 2023
Antibodies (a/t) to antigens (a/g) of human tissue compatibility HLA (human leucocyte antigens) are the main cause of kidney transplant rejection. Antigens of the HLAI class system (loci A, B, C) are present on all nucleated cells of the body, HLA class

HLA-G and the MHC Cusp Theory

open access: yesFrontiers in Immunology, 2022
Human leukocyte antigens (HLA) are significant genetic risk factors in a long list of diseases. However, the mechanisms underlying these associations remain elusive in many cases.

GENETIC POLYMORPHISMS OF HLA-G GENE IN RHEUMATOID ARTHRITIS

open access: yesThe Iraqi Journal of Agricultural science, 2023
This study was aimed to evaluate the influence of Human Leukocyte Antigens- G (HLA-G) gene polymorphisms on the risk of rheumatoid arthritis (RA). In the present study, blood samples were collected from 100 rheumatoid arthritis patients and 100 healthy ...

The frequency of HLA alleles in a population of Inuit women of northern Quebec [PDF]

open access: yesInternational Journal of Circumpolar Health, 2013
Background. Human leukocyte antigen (HLA) alleles code for proteins that are involved in the recognition of foreign antigens and activation of the immune system. The frequency of HLA alleles varies across different populations. Objective. To describe the

HLA-G functions as a restriction element and a transplantation antigen in mice [PDF]

open access: yesInternational Immunology, 1997
HLA-G, a human MHC class I molecule expressed on the trophoblast during pregnancy, was expressed in transgenic mice by recombining the HLA-G gene with a transcriptional promoter from a murine H-2 MHC class I gene. Skin grafts from HLA-G transgenic mice were rejected by non-transgenic mice showing that HLA-G behaves as a xenotransplantation antigen in ...

O papel do complexo principal de histocompatibilidade na fisiologia da gravidez e na patogênese de complicações obstétricas Major histocompatibility complex: its role in the physiology of pregnancy and in the pathogenic mechanisms of obstetric complications

open access: yesRevista Brasileira de Saúde Materno Infantil, 2007
Este trabalho tem por objetivo discutir a estrutura e função dos Antígenos Leucocitários Humanos (HLA), seus métodos de detecção, nomenclatura e os mecanismos imunopatológicos que o associam com a fisiologia da gestação e morbidades obstétricas.

HLA-G and Immune Evasion in Cancer Cells

open access: yesJournal of the Formosan Medical Association, 2010
Acquisition of novel gene products or new antigens in cancer cells elicits a host immune response that results in selection pressure for tumor clones to evade immunosurveillance.

Antibodies for β2-Microglobulin and the Heavy Chains of HLA-E, HLA-F, and HLA-G Reflect the HLA-Variants on Activated Immune Cells and Phases of Disease Progression in Rheumatoid Arthritis Patients under Treatment

open access: yesAntibodies, 2023
Rheumatoid arthritis (RA) is a progressive, inflammatory, autoimmune, symmetrical polyarticular arthritis. It is characterized by synovial infiltration and activation of several types of immune cells, culminating in their apoptosis and antibody ...

Mother-child histocompatibility and risk of rheumatoid arthritis and systemic lupus erythematosus among mothers. [PDF]

open access: yes, 2020
The study objective was to test the hypothesis that having histocompatible children increases the risk of rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), possibly by contributing to the persistence of fetal cells acquired during ...
