Pathogen-Driven Selection in the Human Genome
Infectious diseases and epidemics have always accompanied and characterized human history, representing one of the main causes of death. Even today, despite progress in sanitation and medical research, infections are estimated to account for about 15% of deaths. The hypothesis whereby infectious diseases have been acting as a powerful selective pressure was formulated long ago, but it was not u...

15 صفحه اولPathogen-Driven Selection and Worldwide HLA Class I Diversity
The human leukocyte antigen (HLA; known as MHC in other vertebrates) plays a central role in the recognition and presentation of antigens to the immune system and represents the most polymorphic gene cluster in the human genome [1]. Pathogen-driven balancing selection (PDBS) has been previously hypothesized to explain the remarkable polymorphism in the HLA complex, but there is, as yet, no dire...
متن کاملGenome sequence of the human pathogen Vibrio cholerae Amazonia.
Vibrio cholerae O1 Amazonia is a pathogen that was isolated from cholera-like diarrhea cases in at least two countries, Brazil and Ghana. Based on multilocus sequence analysis, this lineage belongs to a distinct profile compared to strains from El Tor and classical biotypes. The genomic analysis revealed that it contains Vibrio pathogenicity island 2 and a set of genes related to pathogenesis a...
متن کاملPositive selection on the human genome.
Positive selection has undoubtedly played a critical role in the evolution of Homo sapiens. Of the many phenotypic traits that define our species--notably the enormous brain, advanced cognitive abilities, complex vocal organs, bipedalism and opposable thumbs--most (if not all) are likely the product of strong positive selection. Many other aspects of human biology not necessarily related to the...
