There was no significant difference in NK cell (285.58± 182.84 vs 528.92± 208.17) and B cell (186.66± 86.62 vs 334.17± 130.46). The proportion of naive CD4+ T cell (3.75± 0.50 vs 8.54± 1.61) in T lymphocyte subsets in patients with BPH was significantly reduced (P< 0.05). There was no significant difference in memory CD4+ T cell (87.9± 6.37 vs 92.63± 5.94), CD8+CD28+ T cell (60.52± 13.86 vs 64.32± 12.78), CD8+CDDR+ T cell (36.58± 12.87 vs 31.92± 8.54) and CD8+CD38+ T cell (2.1± 1.90 vs 2.55± 2.01).Conclusion: Immune dysfunction raised the risk of viral infection, inflammatory stimulation, and tumor induction in prostate cells, leading to hyperplasia, and immune non-response was potentially a key factor in the transformation of BPH into prostate cancer.Keywords: benign prostatic hyperplasia, lymphocyte subsets, pathogenesis, flow cytometry
