Enhanced Bioactivity of FermentedExtract for Glucose and Immune Modulation.

Excessive glucose absorption is a major contributing factor of metabolic disorders that necessitates effective therapeutic strategies. This study investigates the potential of fermentedextract (FACE) in regulating glucose transport and immune responses under high-glucose stress conditions. Caco-2 intestinal cells and L cells were treated with FACE to determine effects on key glucose-regulating proteins and cytokines. FACE treatment inhibited the expression of glucose transporters SGLT1 and GLUT2 while promoting GLP-1 secretion. This effect was associated with HDAC and somatostatin suppression, along with AMPK-γ upregulation. Notably, FACE inhibited DPP-4 expression, further enhancing GLP-1 stability and function. Immunomodulatory effects also occurred, specifically FACE promotion of T lymphocyte differentiation, with a stronger influence on Th2 cell development. Additionally, FACE increased the secretion of essential molecules for immune balance and inflammation control, including antimicrobial peptides LL-37 and defensin, along with cytokines IL-4 and IL-13. These findings suggest that FACE exerts dual effects of improving glucose regulation and modulating immune responses, highlighting its potential as a novel bioactive material for managing metabolic disorders and enhancing intestinal immunity. Further research is warranted to explore its clinical applicability in therapeutic formulations.
