Elite controllers or suppressors (ES) are HIV-1-infected patients who maintain viral loads of <50 copies/ml without antiretroviral therapy. While HLA-B57 and B5801 alleles are overrepresented in ES, many HLA-B57/B5801 patients become chronic progressors (CP). We show here that HIV-1 infection results in similar levels of downregulation of HLA-B57 and HLA-B5801 molecules on primary CD4(+) T cells from ES and CP. Thus, differences in HIV-1-mediated downregulation of HLA-B57/B5801 molecules do not distinguish ES from CP.
精英控制者或抑制者(ES)是指未经抗逆转录病毒治疗而病毒载量维持在<50拷贝/毫升的HIV-1感染患者。虽然HLA-B57和B5801等位基因在ES中过度表达,但许多携带HLA-B57/B5801的患者会成为慢性进展者(CP)。我们在此表明,HIV-1感染导致来自ES和CP的原代CD4(+) T细胞上HLA-B57和HLA-B5801分子的下调水平相似。因此,HIV-1介导的HLA-B57/B5801分子下调差异并不能区分ES和CP。
