abstract

background: multiple sclerosis (ms) is a t cell mediated autoimmune disease with unknown etiology. appropriate ms therapeutic strategies need thorough understanding of both disease etiology and pathogenesis mechanisms. ligation of tlr-2 and tlr-4 stimulates the production of several cytokines leading to cns autoimmunity and neurodegenerative diseases. objective: to find a relationship between ms disability and tlr-2 and tlr-4 expression on mononuclear cells in the blood of ms patients. methods: forty-five new case (nc) ms patients (33 females and 12 males) and 45 age and gender-matched healthy controls (hc) were recruited to the study. pbmcs were prepared and the expressions of tlr-2 and tlr-4 were assessed by flowcytometry technique using appropriate monoclonal antibodies. results: our results showed that the expression of tlr-2 and tlr-4 proteins in the patients group was significantly higher than that of healthy controls. tlr-2 but not tlr-4 was correlated with expanded disability status scale (edss) scores. conclusion: high expressions of tlr-2 and tlr-4 may represent a state of innate immune activation in patients with ms.

distinct toll-like receptor 3 and 7 expression in peripheral blood mononuclear cells from patients with chronic hepatitis c infection

conclusions this study suggests that decrease in levels of tlr3 and tlr7 expression is a mechanism that may enable hcv to evade the host innate immune response. results in both groups, we had 13 males and 12 females with a mean age of 48.7 ± 16. tlr3 (6.23 ± 0.91 vs. 3.89 ± 0.85, p < 0.001) and tlr7 (1.48 ± 0.82 vs-1.33 ± 1.18, p < 0.001) expressions were significantly lower in patients with ch...

Interleukin-17A and Interleukin-17F mRNA Expressions in Peripheral Blood Mononuclear Cells of Patients with Multiple Sclerosis

Bakground: Multiple sclerosis (MS) is a CD4+ T cell-mediated autoimmune disease affecting the central nervous system (CNS). It was previously believed that Th1 cells were pathogenic T cells in experimental autoimmune encephalomyelitis (EAE). However, the functional role of Th1 cells in EAE has been reconsidered upon the discovery of IL-17- producing T cells which are consider as dominant effect...
