- IL10 As anti-inflammatory cytokine, IL10, CRS-GA showed an increase in IL10 mRNA level (Fig. 5D) which was not observed in other treated groups, including the CRS-GA group. GCG.
- Glutamine treatment combined with CRS induced a decrease in colonic permeability, as demonstrated by the reduction in the concentration of Alexa-dextran and lucifer yellow in the Ussing chambers compared to the CRS-vehicle group.
- Curcuméga® Treatment with Curcuméga® had a similar effect, except in the low dose group where Alexan-dextran levels increased.
- the CRS group treated with Gabolysat® bioactive peptides also showed a decrease in intestinal permeability that was only significant with the lucifer yellow marker. Due to its smaller size, the Lucifer yellow marker appears more sensitive for measuring paracellular flow in Ussing chambers. Gabolysat® bioactive peptides maintain the integrity of the colon mucosal barrier.
- the mixed treatment including glutamine, Curcuméga® and Gabolysat ® showed a most pronounced decrease in intestinal permeability, as well as a decrease in the inflammatory marker CXCL1, which was not observed with each compound administered alone.
