Insights
Interleukin-17A (IL-17A) may play a role in Hepatitis B virus (HBV) infection progression. This review explores IL-17A
Area of Science:
- Immunology
- Hepatology
- Virology
Background:
- Hepatitis B virus (HBV) causes significant liver disease globally.
- Chronic HBV infections can progress to hepatocellular carcinoma (HCC) and liver cirrhosis.
- The role of Interleukin-17A (IL-17A) in viral infections, particularly HBV, is not fully understood.
Purpose of the Study:
- To review current knowledge on the status and association of IL-17A in Hepatitis B infection.
- To explore the potential role of IL-17A in the pathogenesis of HBV-related liver disorders.
Main Methods:
- Literature review of recent studies on IL-17A and HBV.
- Analysis of immunological and genetic factors in HBV progression.
- Examination of IL-17A's role in autoimmune and inflammatory diseases for comparative insights.
Main Results:
- IL-17A is a key cytokine in immune responses, though its viral infection role needs clarification.
- Evidence suggests IL-17A's involvement in autoimmune and destructive immune-related diseases.
- Further research is needed to elucidate IL-17A's specific functions in chronic HBV infection and associated liver damage.
Conclusions:
- IL-17A's precise role in HBV pathogenesis requires further investigation.
- Understanding IL-17A's function could offer new insights into managing HBV-related HCC and cirrhosis.
- This review highlights the need for more research into IL-17A's immunological impact on Hepatitis B virus infection.
Abstract:
Hepatitis B virus (HBV) is one of the most prevalent and infectious agents that leads to liver disease in humans. Five clinical forms of HBV infection exist, including fulminant, acute, chronic, asymptomatic and occult. The chronic, asymptomatic and occult forms are long-term infections that can lead to hepatocellular carcinoma (HCC) and liver cirrhosis. The mechanisms responsible for progression of these forms of the infection to HCC and liver cirrhosis are not yet clearly understood or characterised. However, genetic and immunological parameters may play important roles in the disease. IL-17A is an important cytokine involved in early immune responses against fungal and bacterial infections, but its role in the response against viral infections is yet to be fully clarified. The crucial roles of IL-17A in the pathogenesis of autoimmune and destructive immune-related diseases have been documented and may provide insights into its functions during hepatitis infection. Therefore, the aim of this review was to address the recent information regarding the status and association of IL-17A during hepatitis B infection and its related disorders, including HCC and liver cirrhosis.

NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
