Naive B cells with low differentiation improve the immune reconstitution of HIV-infected patients.

ABSTRACT: Incomplete immune reconstitution happens in some HIV-infected patients who have achieved persistent viral suppression under antiretroviral therapy (ART). We performed single-cell RNA sequencing for peripheral blood mononuclear cells to analyze B cell receptor (BCR) repertoire and B cell subtypes in health controls (non-HIV-infected, HCs), HIV-infected immunological responders (IRs), and immunological nonresponders (INRs). We found that the dominant usage of IGHV gene segments of naïve B cells and memory B cells were IGHV3 and IGHV4, and the diversity of BCR repertoire was decreased in INRs. Differentiation trajectory analysis showed that the low differentiation of naïve B cells was related to satisfactory immune status. The cell cycle of B cells with immune-specific ge
