Outreach + Highlights

The AGP laboratory conducts research on the diversity and biological evolution of human populations, with the main objective of reconstructing the history of world settlement since the origin of Homo sapiens.

Binding affinities of 438 HLA proteins to complete proteomes of seven pandemic viruses and distributions of strongest and weakest HLA peptide binders in populations worldwide

The main function of HLA class I molecules is to present pathogen-derived peptides to cytotoxic T lymphocytes. This function is assumed to drive the maintenance of an extraordinary amount of polymorphism at each HLA locus, providing an immune advantage to heterozygote individuals capable to present larger repertories of peptides than homozygotes.

Harmonizing hybridization dissonance in conservation

A dramatic increase in the hybridization between historically allopatric species has been induced by human activities. Our article proposes a novel view of conservation guidelines, in which human-induced hybridization may also be a tool to enhance the likelihood of adaptation to changing environmental conditions or to increase the genetic diversity of taxa affected by inbreeding depression.

Christelle Vangenot, Médéric Mouterde, Alicia Sanchez-Mazas et Estella Poloni ont fait la couverture du journal “G3” : la maîtrise du feu a-t-elle influencé la diversité génomique humaine ?

Cette hypothèse est avancée dans une étude récente qui a mis en évidence une évolution divergente entre l’humain et le chimpanzé dans une petite famille de gènes impliqués dans la détoxification des molécules produites lors de la combustion de matières organiques.

L'Afrique, 300'000 ans de diversité humaine

Homo sapiens est dʹorigine africaine. C'est une vérité que la génétique a validée depuis longtemps et qui en implique dʹautres. Car si certains petits groupes ont quitté lʹAfrique il y a environ 120'000 ans pour peupler le reste du monde, Homo sapiens a vécu 200'000 ans uniquement sur ce continent. Il connaît ainsi une diversité génétique énorme et beaucoup plus riche que tous les autres continents.

Afrique : 300'000 ans de diversité humaine

L’étonnante diversité humaine visible aujourd’hui en Afrique est ainsi le résultat d’une longue histoire, faite de multiples migrations, interactions, adaptations et innovations. En donnant la parole aux généticien-ne-s et préhistorien-ne-s de l’Unité d’anthropologie de l’Université de Genève, l’exposition se propose de vous raconter l’histoire humaine sur le continent africain.

HLA class I molecular variation and peptide-binding properties suggest a model of joint divergent asymmetric selection

The main function of HLA class I molecules is to present pathogen-derived peptides to cytotoxic T lymphocytes. This function is assumed to drive the maintenance of an extraordinary amount of polymorphism at each HLA locus, providing an immune advantage to heterozygote individuals capable to present larger repertories of peptides than homozygotes.

Variation in NAT2 acetylation phenotypes is associated with differences in food-producing subsistence modes and ecoregions in Africa

Dietary changes associated to shifts in subsistence strategies during human evolution may have induced new selective pressures on phenotypes, as currently held for lactase persistence. Similar hypotheses exist for arylamine N-acetyltransferase 2 (NAT2) mediated acetylation capacity, a well-known pharmacogenetic trait with wide inter-individual variation explained by polymorphisms in the NAT2 gene.
