相关性Hepatitis C E2 is a virus envelope glycoprotein which forms a heterodimer with the E1 protein. E2 inhibits human EIF2AK2/PKR activation, preventing the establishment of an antiviral state. E2 is a viral ligand for CD209/DC-SIGN and CLEC4M/DC-SIGNR, which are respectively found on dendritic cells (DCs), and on liver sinusoidal endothelial cells and macrophage-like cells of lymph node sinuses. These interactions allow capture of circulating HCV particles by these cells and subsequent transmission to permissive cells. DCs are professional antigen presenting cells, critical for host immunity by inducing specific immune responses against a broad variety of pathogens. They act as sentinels in various tissues where they entrap pathogens and convey them to local lymphoid tissue or lymph node for establishment of immunity. Capture of circulating HCV particles by these SIGN+ cells may facilitate virus infection of proximal hepatocytes and lymphocyte subpopulations and may be essential for the establishment of persistent infection.

ELISA analysis of Hepatitis C Virus E2 binding to CD81 receptor, using ab20044 to detect Hepatitis C Virus E2 binding.
A 96-well plate was coated with 100 ng of rho-1D4 antibody. Following overnight incubation at 4°C, the unbound antibody was washed away. The wells were blocked with blocking solution for 2 hours. 100 ng of purified CD81 was added to the wells along with E2 glycoprotein (0.4 to 20 nM) and incubated for 2 hours. ab20044 anti-Hepatitis C Virus E2 antibody (1/2000 dilution) and secondary antibody with alkaline phosphatase conjugate (1/1000 dilution) were added and incubated for 2 hours. Absorbance was measured at 495 nm by a plate-reader.
