Born 29 Oct 1920.
Venezuelan-American geneticist and immunologist who studied the mechanisms and genetic foundation of the immunologic reaction and specifically of its position in sure sicknesses referred to as the autoimmune sicknesses. He acquired a share (with George Snell and Jean Dausset) of the 1980 Nobel Prize for Physiology or Medicine. Benacerraf confirmed that genetic elements in detail associated with the genes that decide an individual’s specific charter of H antigens virtually adjust the interplay some of the numerous cells belonging to the immunological gadget and are thereby essential to the energy of an immunological reaction. He studied the guinea pig’s cappotential to mobilize an immune reaction towards a sure antigen as decided through genetic elements (Ir or immune reaction) genes.
