BACKGROUNDProstate specific antigen (PSA) is a serine protease secreted by the prostatic epithelium. The only known function of the protein is to cleave seminogelin. We wished to determine if PSA activated peripheral blood mononuclear cells (PBMC).METHODSPBMC and selected sub‐populations were cultured with purified PSA. Secretion of IFNγ was measured by cytokine capture flow cytometry and enzyme‐linked immunosorbent assay.RESULTSWe observed secretion of IFNγ and a proliferative response in PBMC cultured with PSA. We found that NK cells were the source of the IFNγ but NK cells were not directly stimulated by PSA. Rather, a soluble factor secreted primarily by CD14 monocytes in response to PSA stimulated NK cells to secrete IFNγ.DISCUSSIONPSA induces a pro‐inflammatory response that results in the secretion of INFγ by NK cells. The presence of large amounts of PSA could contribute to the common finding of inflammatory infiltrates in the prostate. Prostate 66: 1592–1599, 2006. Published 2006 Wiley‐Liss, Inc.
