Antígenos de histocompatibilidad HLA-G y embarazo HLA-G histocompatibility antigens related to pregnancy

Revista Cubana de Hematología, Inmunología y Hemoterapia, 2010
El componente HLA-G es una molécula clase I no clásica (Ib) del sistema principal de histocompatibilidad. Esta adopta 7 isoformas como resultado del empalme alternativo de un mismo RNA inmaduro; 4 se encuentran ligadas con la membrana (HLA-G1-G2-G3-G4) y

Human cytomegalovirus antigen presentation by HLA-G in infected cells

HLA
HLA-E and -G class Ib molecules were considered unrelated to viral antigen presentation. HLA-E binds nonamers from the leader sequences of other HLA-I molecules and the human cytomegalovirus (HCMV) UL40 protein, interacting with CD94/NKG2 NK cell ...

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

International 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 ...

Maturation of antigen-presenting cells is compromised in HLA-G transgenic mice [PDF]

International Immunology, 2001
The human MHC class Ib antigen HLA-G is thought to regulate maternal immune responses during pregnancy. Here we show that expression of HLA-G in transgenic mice diminished cellular immunity by inhibiting maturation of myelomonocytic cells into functional antigen-presenting cells (APC).

Clinical correlates of human leucocyte antigen (HLA)-G in systemic sclerosis [PDF]

Clinical and Experimental Immunology, 2015
Summary Human leucocyte antigen (HLA)-G has a tolerogenic function and could play a role in the pathogenesis of immune-mediated diseases, including systemic sclerosis (SSc). The aim of this study was to evaluate HLA-G serum expression (sHLA-G) and the HLA-G gene 14 base pairs (bp) insertion/deletion (del−/del+) polymorphism in patients ...

Genetic and serological heterogeneity of the supertypic HLA-B locus specificities Bw4 and Bw6 [PDF]

, 1989
Gene cloning and sequencing of the HLA-B locus split antigens B38 (B16.1) and B39 (B16.2) allowed localization of their subtypic as well as their public specificities HLA-Bw4 or -Bw6 to the c~-helical region of the c~ 1 domain flanked by the amino acid ...

Allelic variation in HLA-B and HLA-C sequences and the evolution of the HLA-B alleles [PDF]

, 1989
Several new HLA-B (B8, B51, Bw62)- and HLA-C (Cw6, Cw7)-specific genes were isolated either as genomic cosmid or cDNA clones to study the diversity of HLA antigens.

HLA-G-mediated inhibition of antigen-specific cytotoxic T lymphocytes [PDF]

International Immunology, 1999
In the present study, we demonstrate that the non-classical MHC class I molecule HLA-G impairs specific cytolytic T cell functions in addition to its well-established inhibition of NK lysis. The antigen-specific cytotoxic T lymphocyte (CTL) response analyzed was mediated by CD8(+) T cells specific for the influenza virus matrix epitope, M58-66 ...

The HLA-E Gene encodes two differentially regulated Transcripts and a Cell Surface Protein [PDF]

, 1992
An HLA-E-specific oligonucleotide probe was used to study the expressioonf HLA-E. This probed etects two HLA-E transcripts, 1.8 and 2.7 kb in size, which are present in varying ratios in allt issues and cell lines investigated.

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

Медицина 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
