Evolution of major histocompatibility complex class I and class II genes in the brown bear [PDF]

BMC Evolutionary Biology, 2012
Background Major histocompatibility complex (MHC) proteins constitute an essential component of the vertebrate immune response, and are coded by the most polymorphic of the vertebrate genes.

The porcine Major Histocompatibility Complex and related paralogous regions: a review [PDF]

Genetics Selection Evolution, 2000
The physical alignment of the entire region of the pig major histocompatibility complex (MHC) has been almost completed. In swine, the MHC is called the SLA (swine leukocyte antigen) and most of its class I region has been sequenced.

The primate Major Histocompatibility Complex as a case study of gene family evolution [PDF]

eLife
Gene families are groups of evolutionarily related genes. One large gene family that has experienced rapid evolution lies within the Major Histocompatibility Complex (MHC), whose proteins serve critical roles in innate and adaptive immunity.

Lack of association between alopecia areata and HLA class I and II in a southeastern Brazilian population [PDF]

Anais Brasileiros de Dermatologia, 2016
: Background: Alopecia areata (AA) is a common disorder of unknown etiology that affects approximately 0.7% to 3.8% of patients among the general population. Currently, genetic and autoimmune factors are emphasized as etiopathogenic.

Atlantic cod (Gadus morhua) MHC I localizes to endolysosomal compartments independently of cytosolic sorting signals

Frontiers in Cell and Developmental Biology, 2023
Major histocompatibility complex (MHC) class I and II are crucial for the adaptive immune system because they are involved in peptide presentation to T cells.

Allelic diversity and patterns of selection at the major histocompatibility complex class I and II loci in a threatened shorebird, the Snowy Plover (Charadrius nivosus)

BMC Evolutionary Biology, 2020
Background Understanding the structure and variability of adaptive loci such as the major histocompatibility complex (MHC) genes is a primary research goal for evolutionary and conservation genetics.

Genetic diversity, evolution and selection in the major histocompatibility complex DRB and DQB loci in the family Equidae

BMC Genomics, 2020
Background The mammalian Major Histocompatibility Complex (MHC) is a genetic region containing highly polymorphic genes with immunological functions. MHC class I and class II genes encode antigen-presenting molecules expressed on the cell surface.

Multiple expressed MHC class II loci in salmonids; details of one non-classical region in Atlantic salmon (Salmo salar)

BMC Genomics, 2008
Background In teleosts, the Major Histocompatibility Complex (MHC) class I and class II molecules reside on different linkage groups as opposed to tetrapods and shark, where the class I and class II genes reside in one genomic region. Several teleost MHC

Mice lacking the MHC class II transactivator (CIITA) show tissue-specific impairment of MHC class II expression [PDF]

, 1996
CIITA activates the expression of multiple genes involved in antigen presentation and it is believed to be required for both constitutive and IFN\xce\xb3-inducible expression of these genes.

Allelic diversity and selection at the MHC class I and class II in a bottlenecked bird of prey, the White-tailed Eagle

BMC Evolutionary Biology, 2019
Background Genes of the Major Histocompatibility Complex (MHC) are essential for adaptive immune response in vertebrates, as they encode receptors that recognize peptides derived from the processing of intracellular (MHC class I) and extracellular (MHC ...
