Glycolytic metabolism of CD8+ T‐cells affects susceptibility to human leukocyte antigen‐mediated abacavir‐induced hypersensitivity

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Drug hypersensitivity reactions (DHRs) associated with a specific human leukocyte antigen (HLA) allotype do not manifest uniformly in all individuals within an HLA model population. This scenario highlights the complexity of predicting drug hypersensitivity reaction risk without considering additional factors ...
