Major histocompatibility complex (MHC) is consisted of cluster genes known as human leukocyte antigen HLA, these are committed to process and present antigens T lymphocyte. Corona viruses, belonging a genus the corona viridae family, enveloped viruses containing single stranded RNA 27-32 kb. This study was conducted highlight some observations that may help other researcher for rapid research a...

Aim . To reveal the significance of major histocompatibility complex and human leukocyte antigen evolutionary divergence in transplantation allogeneic hematopoietic stem cells. The article traces evolution discusses reasons for its formation on example recognition system invertebrates, plants, jawed vertebrates humans. concepts immunopeptidome have been defined; data their impact therapy outcom...

the human leukocyte antigen-b27 is one of the class i molecules of the major histocompatibility complex which is strongly associated with ankylosing spondylitis (as) . the strength of the disease association with b27 varies markedly among racial and ethnic populations. it is an allele family, which constitutes about 31 subtypes, with a considerable geographic and ethnic difference in distributi...

background: it has been arguedthat unprecedented degree of human leukocyte antigen (hla) loci polymorphism within a population is requiredto avoid the devastating effects of infectious diseases. the present study was conducted to determine the associations between some of hla classi genes and the outcome of hepatitis b virus (hbv) infection.   methods: using sequential sampling method, 64 indiv...
