Abstract: Objective To identify the expression of long non-coding RNAs(lncRNAs) and their putatively modulated cytokines in human immunodeficiency virus(HIV)-1 infected monocytes and to explore the role of lncRNAs in immunomodulation of HIV-affected host cells.Methods RNAs arrays were used to screen the lncRNAs differentially expressed in HIV-infected monocytes and subsequently confirmed by quantitative real time PCR (qRT-PCR).A siRNA was designed and transfected to the human monocytes, followed by interleukin(IL)-1β, IL-10 and tumor necrosis factor(TNF)-α detection with ELISA.Results The results of the screening assays and qRT-PCR showed that the expression of lncRNA-n266623 was up-regulated in monocytes after HIV-1 infection;the secretions of IL-1β,IL-10 and TNF-α in human monocytes were significantly enhanced following transfection of siRNA targeting lncRNA-n266623 in the monocytes.Conclusion The HIV-1 infection can promote the expression of lncRNA-n266623 which may inhibit the expressions of IL-1β, IL-10 and TNF-α in monocytes and negatively regulate the immune response to HIV-1 infection.
