Distinct cytokine/chemokine network in semen and blood characterize different stages of HIV infection. Vanpouille, C., Introini, A., Morris, S. R., Margolis, L., Daar, E. S., Dube, M. P., Little, S. J., Smith, D. M., Lisco, A., & Gianella, S. AIDS (London, England), 30(2):193–201, January, 2016. doi abstract bibtex OBJECTIVE: The cytokine/chemokine network is used by the innate and adaptive immune system to orchestrate effective immune responses. Here, we describe the cross-sectional association between cytokine levels and stage of HIV infection to gain novel insights into HIV-1 immunopathogenesis and identify novel therapeutic targets. DESIGN: Concentrations of 31 cytokine/chemokines were retrospectively measured in blood and seminal plasma collected from 252 individuals enrolled in four well characterized cohorts: HIV-uninfected, untreated HIV-infected in early phase of infection, untreated HIV-infected in late phase of infection, and HIV-infected on antiretroviral therapy with undetectable HIV RNA levels in blood (\textless50 copies/ml). METHODS: Cytokine/chemokine levels were measured by multiplex-bead array. Comparisons between groups were performed by Mann-Whitney U-test and P values were adjusted for multiple comparisons using the Benjamini-Hochberg method. RESULTS: Presence of HIV-infection skewed the cytokine/chemokine network towards a pro-inflammatory response in both blood and semen compared to HIV-uninfected controls. Such changes emerged within the first weeks of infection and were maintained thereafter: Among untreated HIV-infected individuals, none of the 31 measured cytokines were significantly different between early and later stages of infection. Suppression of plasma HIV RNA with ART did not result in normalization of the levels of pro-inflammatory cytokines in blood. In semen, several pro-inflammatory cytokines were even further upregulated in ART-treated compared with HIV-uninfected and HIV-untreated individuals. CONCLUSION: A profound disruption in the cytokine/chemokine network is evident in blood and semen from the earliest stage of HIV infection shortly after the first detection of systemic viremia. These changes are maintained throughout the chronic phase of the infection and do not normalize despite ART and suppression of plasma HIV RNA.
