| Alternate Names | C, External core antigen, HBeAg, Precore protein, p25 |
| Background | External core antigen is a ~24 kDa protein. May regulate immune response to the intracellular capsid in acting as a T-cell tolerogen, by having an immunoregulatory effect which prevents destruction of infected cells by cytotoxic T-cells. This immune regulation may predispose to chronicity during perinatal infections and prevent severe liver injury during adult infections. |
