context the aim of this review was to address the recent data regarding the role of il-17a in the pathogenesis of depression and its complications, such as cancer. evidence acquisition this review article summarizes the recent data on the role of il-17a in depression, using the pubmed and google scholar databases. results it has been documented that depression may alter the immune response via ...

Abstract Background B cells play an important role in the immune system due to production of the immunoglobulin and secreting several cytokines. It has been shown that B cells produced successfully in the presence of stem cell factor (SCF) and Flt3 ligand (Flt3L). IL2, IL7, and IL15 cytokines as -common family have an essential cytokines may support either synergistically or in an additive m...

Background: Preeclampsia is a common pregnancy-specific disorder associated with significant maternal and fetal morbidity and mortality worldwide. It has been proposed that the imbalance between two CD4+ T cell subtypes, regulatory T cells (Treg) and T-helper 17 cells (Th17), is involved in the pathophysiology of preeclampsia. Objectives: To determine the serum levels of IL-17, IL-21, IL-23 and...

About thirty years ago, the interlukin-6 (IL-6) which is the proinflammatory cytokine, was detected as the differentiation factor of B cell. IL-6 is able to induce maturation in B cells and as a result, B cells achieve the ability to produce antibodies. In addition to immune responses, the role of IL-6 has been known in neurogenesis (neurons and glial cells). The studies have showed that the ab...

Background: Umbilical cord blood (UCB) is an alternative source of hematopoietic stem cell transplantation (HSCT), used in Leukemia treatment. CD26+ cells, a fraction of CD34 positive cells, are a major population of UCB cells which negatively regulate the in vivo homing and engraftment of HSCs. CD26 is highly expressed in various cells such as HSCs, immune cells, fibroblasts, and epithelial ce...

Background: Increased evidences have shown that unexplained recurrent spontaneous abortion (URSA) is associated with inflammatory responses and breakage of immunological autotolerance. Therefore, the balance between Th17 and Treg cells may elucidate the pathophysiology of URSA. Objective: To investigate the serum concentration of regulatory and inflammatory cytokines associated with Treg and Th...

different research groups have extensively studied the associations of cytokine gene polymorphisms in different diseases. the role of cytokines gene polymorphisms in multiple sclerosis (ms), as a chronic immune-mediated neurodegenerative disease, has been previously reported in the various populations. for determining pro-inflammatory cytokine gene polymorphisms, 100 relapsing remitting multipl...

Background: Inflammatory bowel disease, an autoimmune disease, has two clinical manifestations including Crohn’s disease and ulcerative colitis (UC). IL-17 has been the target of intensive research in autoimmune diseases. The influence of Toll like receptor 4 (TLR-4) gene polymorphisms on IL-17 production has also been revealed in UC patients and tissue inflammation in mice. Objectives: To inve...

il-1β and il-17a are two cytokines with strong proinflammatory activities and are now known to be involved in a number of chronic inflammatory disorders. high-mobility group box 1 (hmgb1) is a nuclear protein regulating the expression of these proinflammatory cytokines. the nlrp3 inflammasome promotes the maturation of the il-1β and its activation has been shown as a critical mechanism in the p...
