Abstract

The differentiation and response ofCD8+ T cells is vital in host defense against human immunodeficiency virus type 1 (HIV-1). MicroRNA (miR)‑155 is an important regulator of T cell differentiation. However, the profile of miR-155 in HIV‑1 infected individuals and its association with CD8+ T cell differentiation remain to be fully elucidated. The present cross‑sectional study was performed involving 63 HIV‑1‑infected patients undergoing highly active antiretroviral therapy (HAART), 31 HAART‑naïve patients and 35 healthy controls. The levels of miR‑155 in CD8+ T cells were detected using reverse transcription‑quantitative polymerase chain reaction analysis. Subsets of CD8+ T cell differentiation were detected using flow cytometry. The results revealed that the discord controllers and HAART‑naïve patients showed higher percentages of effector and effector memory cells, and lower percentages of naïve cells (P<0.05). The levels of miR‑155 in CD8+ T cells from the HIV‑1‑infected patients were higher, particularly in the discord controllers and HAART naïve patients (P<0.01). The expression levels of miR‑155 were positively correlated with the percentages of effector and effector memory CD8+ T cells, and negatively correlated with the percentages of naïve and central memory CD8+ T cells (P<0.01). Taken together, these findings suggested that the levels of miR‑155 in CD8+ T cells of patients with HIV-1 were increased and asso­ciated with CD8+ T cell differentiation.
