The relationship between expression of Toll-like receptor 4 in chronic hepatitis C patients and different stages of liver fibrosis

2017 Gastroenterol Hepatol Bed Bench 10;4 (278-283)

Aim: The objective of this work is to find out whether there is a relation between the expression of TLR4 and fibrosis progression in chronic HCV patients. Background: Toll-like Receptor 4 (TLR4) is a pattern recognition receptor whose activation results in the production of several pro-inflammatory cytokines. Methods: Fifty patients with chronic HCV were included. They were divided into group A: 40 patients (F1-F4) and group B (control group) which included ten patients (F0) based on fibroscan value. All patients were exposed to clinical and laboratory evaluations preliminary to antiviral therapy, assessment of TLR4 mRNA by Real Time- PCR. Results: Twenty-eight males and 22 females with a mean age 28.9+/-6.1 years. The mean TLR4 expression is 11.2+/-7.4 folds, TLR4 expression in F0 group is 2.8+/-1.9, in F1 group 4.8+/-1.5, F2 group 10.2+/-2.5, F3 group 16.8+/-1.5 and in F4 21.3+/-3.6 folds (p
