MicroRNA profile in immune response of alveolar and cystic echinococcosis patients

Abstract

It is known that miRNAs are effective in immune response in the diagnosis and treatment of many infectious diseases. However, the miRNAs profile is unknown in Alveolar and Cystic Echinococcosis which can be fatal if left untreated. The miRNAs profile that activates the T and B cells forming the immune system in Alveolar and Cystic Ecinococcosis patients was investigated in this study. A total of 50 liver tissue samples were obtained from Alveolar and Cystic Echinococcosis patients in Kilis State Hospital Pathology Laboratory in southeast of Turkey. The circulating cell-free miRNAs were evaluated by a quantitative real-time polymerase chain reaction, statistically calculated within ΔΔCt values and fold changes were evaluated by Welch T test, in which p <0.05 were considered to be significant. Twenty-five microRNAs, including let-7a 5p, let-7c, let-7e-5p, miR-15b-5p, miR16, miR-17-5p, miR-23a-5p, miR-24-3p, miR-25-3p, miR26a-3p, miR-26b-3p, miR-29b-3p, miR-29c-3p, miR-30a-5p, miR-30b-5p, miR-30c-5p, miR-30d5p, miR-30e-5p, miR-98-5p, miR-101-3p, miR-106b-5p, miR-125b-5p, miR-142-5p, miR-222-3p and miR-223-3p were found as down-regulated in Alveolar and Cystic Echinococcosis patients than control groups. Twelve miRNAs, including miR-15a-5p, miR-21-5p, miR-27a-3p, miR-29a3p, miR-146a-5p, miR-181a-5p, miR-181b-5p, miR-181d, miR-181c-5p, miR-195-5p, miR-214- 3p and miR-365-3p were found as up-regulated in Alveolar and Cystic Echinococcosis patients than healthy person. It has been shown that T and B cell activities are related in the progressive of both Alveolar and Cystic Echinococcosis in this study. The miRNA panel activated by T and B cells may be important for exploring the mechanisms underlying early development in Alveolar and Cystic Echinococcosis providing novel information that may be used to discover new therapeutics for these diseases.
