چکیده

Cystic echinococcosis (CE) is caused by infection with the larval stage of the cestode Echinococcus granulosus. It is one of the world's major zoonotic infections. Variability and severity of clinical expression of this parasitosis are associated with duration and intensity of infection. They are also related to the variety of human immunological responses to the hydatic antigens. The aim of this work is to study the inflammatory response associated with human hydatidosis by evaluating the possible roles of the proinflammatory cytokines in hydatic patients. We investigated the patterns of IL-12 and IL-8 in serum from Algerian hydatic patients. Serum IL-12 and IL-8 levels are significantly higher in patients with hydatidosis than in control subjects. Furthermore, cytokines secretion correlates with disease statues (cystic localizations and clinical stage). These data indicate that infection with E. granulosus is associated with high levels of circulating IL-12 and IL-8. Moreover, our data, to our knowledge, constitute the first report of IL-12 and IL-8 diffusion into the hydatid cyst. Our results underline the permeability of the cyst wall to the soluble immune system of the host. The relationship between cyst fertility and cytokine infiltration indicates a strong host-parasite interaction. All these findings have important implications for the diagnosis of hydatidosis in humans.

Evaluation of IL-17 and IL-10 Production in Infectious Mononucleosis in EBV Patients

Epstein–Barr virus is primarily the cause of acute infectious mononucleosis and can also cause lymphoma and autoimmune diseases. Th17 cells, which are a unique subset of ThCD4+ cells, direct the infection toward inflammation through production of inflammatory cytokine IL-17. In contrast, Treg Foxp3 cells inhibit inflammation through secretion of anti-inflammatory cytokine IL-10, leading to chro...

    Background & Aim: Multiple sclerosis(MS) is the most common inflammatory disease of central nervous system which is caused by an autoimmune process leading to destruction of myelin sheath. In this disease, CD4+ T–lymphocytes, mostly of TH1 phenotype, play important roles in destruction of neuronal tissues.  Because of the probable etiologic participation of EBV virus in immunopathogenesis o...
