Potential of Lactobacillus acidophilus to modulate cytokine production by peripheral blood monocytes in patients with endometriosis
Abstract
Background and Objectives: Endometriosis is defined as the presence of endometrial tissue outside the uterine cavity. Pe- ripheral blood monocytes cells (PBMCs) may have altered function to some extent in women with endometriosis. Lactoba- cillus acidophilus is a probiotic bacterium within the human bodywith the ability of alleviating many inflammatory diseases. Here, we examined the effect of L. acidophilus on PBMCs of endometriosis patients.
Materials and Methods: In this study, peripheral blood samples were obtained from endometriosis patients (n=11) and non-endometriosis individuals (n=11). After isolation of peripheral blood mononuclear cells with Ficoll, cells were cultured in the presence and absence ofphytohemagglutinin. Also, these cells were co-cultured with 1×106 CFU/ ml of L. acidophilus. IL-6 and IL-1 cytokines were measured by ELISA methodand the two groups were evaluated and compared.
Results: The results showed that in endometriosis patients, the production of pro-inflammatory cytokines, including IL-1 and IL-6, by PBMC was increasedcompared to non-endometriosis subjects, and stimuli such as PHA intensified this elevation. Also, L. acidophilus increased the levels of pro-inflammatorycytokines including IL-1 and IL-6. However, the production of these cytokines decreased due to the modulatory properties of bacterial cells after 48 h.
Conclusion: According to the results of the current study, IL-1 and IL-6 production was significantly increased in PMBCs of endometriosis patientscompared to that of the healthy controls. Also, Lactobacillus acidophilus was considered as an antigenic compound and induced IL-1 and IL-6 production.According to these results, probiotics can be further used for the treatment of endometriosis patients and more investigations are needed to confirm these results.
