The present work was designed to investigate the potential role of TLR7 and IFNL1 in chronic hepatitis C (CHC) in relation to viral replication and liver injury.
Carriage of the C allele in three SNPs of TLR3 (rs3775290, rs3775291, and rs5743312), the C allele in TLR7 (rs3853839) in females only, and the C allele in TLR8 (rs3764879) in males only were significantly higher in SVC group than CHC group (P < 0.001), while carriage of the T allele in TLR7 (rs179008) in females only and the A allele in TLR8 (rs3764880) in both males and females were significantly higher in CHC infection more than SVC group (P < 0.001).
Our study is aimed to investigate ex vivo, liver expression of TLR2, TLR3 and TLR7, which are more involved in the immune-pathogenesis of CHC, and to explore possible correlations with features of disease.
