Analysis of peripheral T cells and the CC chemokine receptor (CCR5) delta32 polymorphism in prostate cancer patients treated with carboxymethyl-glucan (CM-G).

β-Glucan, derived from Saccharomyces cerevisiae, is a biological response modifier which affects the innate and adaptive immune responses. The CCR5 chemokine receptor is crucial for immune cell responses. In this study, the effects of the carboxymethylated form of β-glucan (CM-G) on the lymphocyte population of CCR5 genotype patients with prostate cancer (PCa), undergoing androgen deprivation therapy (ADT) was assessed.
