Dengue virus serotype 2 (DENV-2) is a predominant cause of severe dengue and a key determinant of dengue-associated liver injury. This review integrates recent findings on the molecular and cellular mechanisms of DENV-2 hepatotropism, focusing on viral replication, cellular stress responses, and immune-mediated damage. The interplay between hepatocytes, Kupffer cells, and innate and adaptive immune responses, culminating in cytokine storm and immune-mediated hepatocyte apoptosis, is dissected. Integrating in vitro and in vivo findings, this review highlights how viral replication and immune dysregulation converge to cause hepatic injury. Future research should prioritize antiviral, immunomodulatory, and hepatoprotective approaches aimed at reducing the risk of dengue-associated liver failure.
