Surface modification of peptide-based poly(lactic-co-glycolic) acid (PLGA) nanoformulations with p8 also enhanced the maturation of dendritic cells (DCs) from HLA A2.1 transgenic mice. DCs were cultured for 24 h upon stimulation with the mix of p8-PLGA-chCPAp, p8-PLGA-chH1p, and p8-PLGA-KMP-11p nanoformulations (mix C) or PLGA nanoparticles surface modified with p8. (A) Representative histogram plots of CD40, CD80, CD86, major histocompatibility complex (MHC) class I, and class II molecules levels. (B) Diagram demonstrating the percentage (%) of DCs expressing the co-stimulatory and MHC class I and class II molecules. (C) Diagram demonstrating the mean fluorescence index (MFI) of DCs expressing the co-stimulatory and MHC class I and class II molecules. Results are expressed as the mean ± SD of three independent experiments. Significant differences are indicated by *p < 0.05, **p < 0.01, or ***p < 0.001.
