Tumor-specific immunotherapy via HSP-conjugated vaccine Glioma antigens bound to HSPs elicit specific immune responses • Following immunization, HSPPC-96–antigen complexes are internalized by APCs via CD91 receptor • APCs then present to CD8+ T cells on MHC class I Resected tumor CD91 APC HSPPC-96–antigen MHC I TCR CD8+ T cell HSP=heat shock protein; APCs=antigen-presenting cells; MHC=major histocompatibility complex; PFS=progression-free survival; TCR=T-cell receptor.
