Percentage of macrophage cell viability after exposure to (a) CPHD and (b) its cationic peptide fraction. CPHD = cricket protein hydrolysates after simulated digestion with gastrointestinal enzymes. Cells were incubated with CPHD (100–1000µg/mL), cationic peptide fraction (0.5–10 µg/mL), or DMSO (0.25%), for 12 h, to evaluate cytotoxicity by MTT assay, with peptides. There was no significant (p > 0.05) reduction in viability, as compared to the DMSO-treated cells. Data represent the mean ± SD representative of eight (n = 8) independent experiments.
