In a B16BL6 tumor model, the co‐delivery system induced a stronger antitumor effect than the simple mixture of exosomes and CpG.[87] In another study, SAV‐exo was incorporated with biotinylated GALA (a pH‐sensitive fusogenic peptide that induces pore formation at pH 5) to achieve efficient cytosolic delivery and cross‐presentation of exosomal tumor antigens.[88] Harvesting exosomes from dying tumor cells that underwent ICD is another approach to improving immunogenicity. Here, GLA is linked to neoplasm.
