Definition / meaning of autologous heat-shock protein 70 peptide vaccine AG-858

A recombinant cancer vaccine made with tumor-derived heat shock protein 70 (HSP70) peptide complexes. HSP70 associates with antigenic peptides, transporting them into antigen presenting cells (APC) for processing. Tumor-derived HSP70-peptide complexes used in vaccine preparations have been shown to prime tumor immunity and tumor-specific T cells in animal models.
