background: management of multiple sclerosis (ms) is based on the usage of immunosuppressive and immune-modulating medications. cytokines play an important role in the pathogenesis of ms. objective: to evaluate the effects of rapamycin on the concentrations of th1/th2/th17 serum cytokines in patients with ms. methods: six patients with relapsing remitting ms as a case group and 6 healthy indivi...

TNFα is one of the most important inflammatory cytokines which induces caspase and apoptotic process. There are two forms of TNFα: soluble TNFα (solTNFα) and transmembrane TNFα (tmTNFα). These inflammatory cytokines have two receptors namely TNRF1 and TNRF2. The attachments of the cytokines to those receptors induce the TRAF and activate the NK-Kb. TNFR1 is f...

chronic idiopathic urticaria is defined as recurrent hives occurring for at least 6 weeks. in  the  majority of  cases, there  is no  identifiable underlying etiology despite  extensive evaluation. a subset of these patients is classified as having autoimmune urticaria defined by the presence of a functional igg antibody to the α subunit of the high-affinity ige receptor (fceria) or to ige. the...

shiga toxins (stxs) are bacterial virulence factors produced by shigella dysenteriae serotype 1 and escherichia coli strains. stxs are critical factors for the development of diseases such as severe bloody diarrhea and hemolytic uremic syndrome. additionally, stxs trigger the secretion of pro- inflammatory cytokines and chemokines, particularly in monocytes or macrophages. the inflammatory cyto...

cytokines have been introduced as critical inducers in the development of th subpopulations.cytokines like il-10 are involved in inducing regulatory t cells such as type 1 regulatory t (tr1) cells cells. il-22 is a member of il-10 family of cytokines, and il-28a is a member of ifn-γ family. in this study, cord blood mononuclear cells (cbmc) from normal healthy individuals were isolated by ficol...
