MOLECULAR MECHANISMS OF PATHOGENESIS OF VIRAL HEPATITIS A
Keywords:
viral hepatitis A, molecular mechanisms, pathogenesis, viral replication, hepatocytes, immune response, liver inflammation, cytokines, diagnostics, vaccination.Abstract
The article is devoted to the molecular mechanisms of pathogenesis of viral hepatitis A (HAV), an infectious disease that causes acute inflammation of the liver. Hepatitis A virus is an RNA-containing virus that is transmitted by the fecal-oral route and in most cases leads to self-healing. However, the molecular processes underlying the pathogenesis of the disease include complex interactions of the virus with liver cells, activation of the immune response and the development of inflammation.
The article discusses the key stages of hepatocyte infection, the mechanisms of virus penetration into the cell and replication of the viral genome, as well as the effect of viral proteins on cell metabolism. Particular attention is paid to the immune response of the body, including the activation of innate and adaptive immunity, as well as the role of cytokines in inflammation. Description of the molecular mechanisms of liver cell damage and inflammation contributes to a better understanding of the pathogenesis of viral hepatitis A and opens up new horizons for the development of more effective methods for diagnosis, treatment and prevention of the disease.
The article also emphasizes the importance of host genetic factors in the pathogenesis of HAV and considers the prospects for using molecular approaches in therapy and vaccination against the virus.
