Our identification of plasma CXCL9 and CXCL10 as plasma biomarkers associated with HIV infection is consistent with previous studies [7], [37], [39], [40], [41], and increased CXCL10 and IFNα were previously detected in HIV patients on cART [7], [19], [37], [41], [42]. Here, CXCL9 is linked to HIV infectious disease.
