In the trial, some class II B sequences were found in both class II loci, presumably by gene conversion or inversion, so that identical sequences would receive different names. This situation prompts further suggestions to the new nomenclature system. In summary, there has been progress, but ...
The Major Histocompatibility Complex (MHC) is a key component of the adaptive immune system of all vertebrates and consists of the most polymorphic genes known to date. Due to this complexity, however, MHC remains to be characterized in many species including any Neotropical cichlid fish. Neotropic...
While epitope spreading may contribute to robust protection against pathogens, it is also thought to play a central role in the pathogenic process of autoimmune diseases by expanding the range of cellular components and tissues targeted by the immune system15,16. However, it remains unclear how ...
The reporting and naming of HLA alleles and haplotypes in this review follows the HLA nomenclature system described by Marsh (Marsh et al.2010). The asterisk “*” sign indicates that the typing has been performed by a molecular method. The digits before the first colon (field 1) define the...

(gene flow) and the breeding system of the species under study [106,107]. In contrast, the ability of natural populations to maintain genetic variation in functional genes depends on the selection pressures involved. Balancing selection is thought to counteract the effects of genetic drift and to...
The repertoire of MHC alleles and the level of expression of each of these alleles is a critical aspect of how the immune system responds to pathogens. HIV and other intracellular pathogens are known to preferentially infect distinct leukocyte subsets, thus the particular MHC class I alleles expres...
For example the allele HLA-B57 has more than 100 closely related alleles that vary in one or more amino acids, according to the WHO Nomenclature Committee for Factors of the HLA System, labelled HLA-B*57:01:01 to HLA-B*57:82. The full or partial sequence of all known HLA genes and ...
