HspE7 is a recombinant chimeric protein composed of the heat shock protein 65 (Hsp65) from Mycobacterium bovis, and the human papilloma viral (HPV) protein E7. Hsp65, similar to other members of its family of proteins, elicits a strong immune response and may be used to design vaccines against a number of different cancers. E7 protein is involved in carcinogenesis of anal and cervical tumors, and represents a tumor antigen that may be specifically targeted by lymphocytes. It is being developed by StressGen Biotechnologies Corp.
Mechanism of action:
HspE7 works by efficiently delivering the E7 antigen to dendritic cells, which have a natural affinity for Hsp. Dendritic cells are known to be the most potent cells in the body for triggering immune responses. Coupling E7 to Hsp takes advantage of the Hsp receptors that dendritic cells express on their surface to introduce E7, as part of a larger fusion protein, into the dendritic cells.
