SCFA treatments decrease NT expression in the intestine following NTG injection. Positive NTs immunostaining is found in NTG-injected mice (B,I;K,R) compared to the sham animals (A,I;J,R). SCFAs of 30 mg/kg treatments (D,G,M,P), but most of all SCFAs of 100 mg/kg treatments (E,N,H,Q), reduce this positive staining. Mice treated with 10 mg/kg of SCFAs do not show any significant reduction in BDNF and NT expressions (C,F,L,O). Data are representative of at least three independent experiments; one-way ANOVA test. *** p < 0.001 vs. sham; # p < 0.05 vs. NTG; ## p < 0.01 vs. NTG; ### p < 0.001 vs. NTG. N = 10 mice/group for each technique.
