Association of toll-like receptors single nucleotide polymorphisms with HBV and HCV infection: research status.

BACKGROUND

Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections have become increasingly severe worldwide and are a threat to public health. There have been a number of studies conducted recently on the relationship of single nucleotide polymorphisms (SNPs) to innate immune receptor genes such as toll-like receptors (TLRs). Some literature suggests that SNPs of TLRs are associated with HBV and HCV infection. We summarized the role of gene polymorphisms associated with HBV and HCV infections and explored their possible mechanisms of action.

METHODOLOGY

PubMed and Web of Science were used to perform the literature review. Related articles and references were identified and used to analyze the role of gene polymorphism in HBV and HCV infection.

RESULTS

gene polymorphisms may have beneficial or detrimental effects in HBV and HCV infection, and some SNPs can affect disease progression or prognosis. They affect the disease state by altering gene expression or protein synthesis; however, the mechanism of action is not clearly understood.

CONCLUSIONS

Single nucleotide polymorphisms of TLRs play a role in HBV and HCV infection, but the mechanism of action still needs to be explored in future studies.
