Human Immunodeficiency Virus–Induced Apoptosis of Human Hepatocytes via CXCR4

Abstract excerpt

Human immunodeficiency virus (HIV) infection is commonly associated with liver dysfunction. The X4 HIV glycoprotein 120 envelope (env) induces apoptosis in T cells and neurons via the HIV coreceptor CXCR4. Therefore, we investigated whether hepatocyte death could result from the HIV env signaling through CXCR4 on the hepatocyte. We demonstrated that hepatocytes in humans express CXCR4 on the cell surface....
