Tight junction proteins gene expression in Caco-2 barrier model after 24 h of incubation with 50 µg/ml of LSNPs and FNPs, and 150 µg/ml of CNPs and HNPs. A TJP1, B OCLN, C CLDN3 and D CLDN5. n = 3; mean ± SEM; ⁺p < 0.05 versus Ctrl; ⁺⁺p < 0.01 versus Ctrl; *p < 0.05 versus untreated; **p < 0.01 versus untreated
