Background: The function of the immune system in prostate cancer (PC) might promote carcinogenesis. PC is a common
cancer in men. Regulatory B cells (Bregs) are a new subtype of B cells that have suppressive roles in the immune system. Interleukin-10 (IL-10) is a dominant mediator of immune suppression released by Bregs.
Objective: The purpose of this research was to examine the frequency of CD19+IL10+ B cells and IL-10 mRNA expression
in patients with PC compared to patients with benign prostatic hyperplasia (BPH).
Methods: Forty paraffin tissue samples from patients with PC and 32 paraffin tissue samples from patients with BPH were entered
in this study. The immunohistochemistry staining was used to evaluate the pattern expression of CD19 and IL-10 markers.
IL-10 mRNA expression in fresh tissue was determined by real time-polymerase chain reaction (RT-PCR).
Results: The frequency of CD19+IL-10+ B cells and IL-10 mRNA expression in PC patients were significantly higher than
patients with BPH. Also, there was no meaningful relationship between the frequency of IL-10+CD19+ B cells and gleason
scores in patients with PC.
Conclusions: Our findings suggested that frequency of IL-10+CD19+ B cells correlates with progressive stage of PC.
Prostate cancer; benign prostatic hyperplasia; IL-10+CD19+ B cells.
