Regulation of the Immune Tolerance System Determines the Susceptibility to HLA-Mediated Abacavir-Induced Skin Toxicity

The authors showed the importance of immune tolerance for idiosyncratic drug toxicity (IDT) onset and determine whether it was susceptible to a common IDT, HLA-B*57:01-mediated abacavir-induced hypersensitivity, using CD4+ T cell-depleted programmed death-1 receptor-deficient HLA-B*57:01 transgenic mice
