Fig. (1) Schematic representation of the CHI-E7p protein and VLP. The HBsAg(S) protein is represented as it is hypothesized to appear in the membranes of the Golgi apparatus before assembling into VLPs, i.e. a polypeptide with four transmembrane domains with the CCL19 at its N-terminus and IL-2 plus E7p at its C-terminus. On the right, a cartoon of a hypothetical VLP made of CHI-E7p.
