PG - 198-204 AB - Dendritic cells (DCs) play key roles in regulating the immune response using the specialized function of processing and presenting antigens. Prolactin (PRL), a hormone produced by the pituitary gland, participates in DC maturation and function. The present study was aimed to determine the frequencies of peripheral blood DC subpopulations of myeloid DC (MDC) and plasmacytoid DC (PDC) in hyperprolactinemic (HPRL) women compared to normal healthy volunteers. This study was conducted on 70 women, including 35 HPRL patients and 35 matched healthy controls, whose PRL serum levels were in the normal range (lower than 25 ng/mL). Serum thyroid-stimulating hormone (TSH) levels were measured in both groups as an indicator of normal thyroid function. The electrochemiluminescence immunoassay method was applied to measure the serum levels of TSH and PRL. The frequencies of MDC and PDC in the peripheral blood samples of both groups were determined by flow cytometry. The mean serum PRL levels in the HPRL patients and healthy individuals were 46.41+/-21.96 and 13.75+/-11.19, respectively (p<0.0001); however TSH levels in both groups were similar and within the normal range (0.4-4.5 mIU/mL) (p=0.2). The frequencies of both MDC and PDC subpopulations in the peripheral blood of HPRL patients were significantly lower than they were in the healthy controls. However, the ratio of MDCs/PDCs in HPRL patients was not significantly different between the two groups (p=0.8). Our study revealed that an increased level of serum PRL may lead to a reduction in the number of MDC and PDC subpopulations. These results could help clarify the complex relationship between the immune system and the neuroendocrine axis and may be of potential use in understanding the pathogenesis of endocrine and immune disorders.
