Macrophage Inflammatory Protein-3 Alpha (MIP-3α)/CCL20 in HIV-1- Infected Individuals

OBJECTIVE: T cells. The role and prognostic value of blood levels of MIP-3α in HIV-infected individuals has yet to be described. METHODS: We determined the serum levels of MIP-3α, and IFN-γ, in 167 HIV-1-infected and 27 HIV-1-uninfected men participating in the Multicenter AIDS Cohort Study (MACS). The blood biomarkers were measured using enzyme-linked immunosorbent assays (ELISA) and the cell phenotypes using flow cytometry. RESULTS: T cells (p=0.0002) and with serum levels of IFN-γ (0.006). CONCLUSION: T cells in HIV-1-infected men. A higher blood level of MIP-3α may be representation of locally high level of MIP-3α and more recruitment of immature dendritic cell at site of infection. Involvement of CCR6/CCL20 axis and epithelial cells at the recto-colonel level may enhance sexual transmission of HIV-1 in MSM and may be useful as a prognostic marker in HIV-1-infection and AIDS.
