Název v původním jazyce

Genetic variability of MHC class IIB genes associated with parasite diversity in European populations of chub (Leuciscus cephalus Linnaeus, 1758)

Popis výsledku v původním jazyce

The genes of the major histocompatibility complex (MHC) are the most polymorphic loci known for vertebrates. The host- pathogen coevolution and parasite-driven balancing selection have a extensive contribution to the high level of allelic diversity in MHC genes. The polymorphism of MHC molecules can be extremely huge; there are a large number of genetic variants (alleles) at each genetic locus. Individuals with higher number of different MHC molecules are able to recognize a broader spectrum of pathogenor parasite derived antigens, and then pathogens or parasites evolve to evade common MHC genotypes, giving rare MHC genotypes a selective advantage. A common European cyprinid, the chub, Leuciscus cephalus (L.), was chosen as a model organism for investigating the hypothesis of pathogen-driven selection under natural conditions, mediated either through heterozygous advantage (overdominant selection) or negative frequency-dependent selection (rare allele advantage hypothesis).
