A Schematic description of the mechanism of the in situ vaccine effect induced by α-melittin-NPs. B Fluorescence images of excised LNs from C57BL/6 mice subcutaneously injected with 20 nmol FITC-melittin, FITC-α-peptide-NPs, and FITC-α-melittin-NPs (quantification was based on the FITC content). C Scheme of the bilateral flank tumor model established with B16F10 cells and the treatment scheme of different drugs. D Tumor growth of the injected tumor and distant tumor.
