Abstract
Background: Circulating miRNAs are recently used as promising biomarkers for infectious diseases. The aim of this study was to identify plasma miRNAs for infection detection and monitoring the immune status of HIV infection. Methods: A cohort of 128 plasma samples from HIV-1 infected subjects and 37 samples from healthy donors were analyzed by TaqMan Low-Density Array (TLDA) method to find the differentially expressed miRNAs, in the light of HIV-1infected patients with low ( 350 cell/μL) CD4+ T cell count. Results: Seven miRNAs (miR-29a, miR-223, miR-27a, miR-19b, miR-151-3p, miR-28-5p, miR-766 and miR-30a-3p) were significantly associated with CD4+ T cell count (P Conclusions: We have identified highly sensitive and specific signatures of circulating miRNAs enabling non invasive detection and immune status monitoring of HIV-1 infection.
