Effect of colonic batch samples from healthy and PD donors on the transepithelial electrical resistance of the Caco-2/THP1 co-cultures. TEER was measured 24 h after dosing with probiotic (P). Samples without added probiotic were used as blanks (B). Δ shows the difference between control and probiotic.
