Moreover, we observed an increase in the histopathological scores (Figure 7g), a decrease in the expression of ileal TJPs (Figure 7h), and an increase in serum LPS levels (Figure 7i) following GLPG0974 treatment or GPR41 knockout, compared to L. gasseri FWJL-4 treated NEC WT mice. Here, FFAR3 is linked to necrotizing enterocolitis.
