Phytic acid reduces the activity of specific cellular signaling pathways involved in inflammation in mouse models of intestinal inflammation and in human intestinal cells exposed to bacterial...
Mechanism
Synthesis from 1 study
Phytic acid blocks a cellular alarm system that triggers gut inflammation. By stopping this alarm from turning on, it prevents the gut lining from breaking down and keeps harmful bacteria from leaking through, which reduces swelling and damage in the intestine.
Most probable mechanism
Phytic acid enters gut cells and blocks a key signaling chain that normally turns on inflammation. This stops a protein called NF-κB from moving into the cell’s nucleus to activate genes that make inflammatory chemicals. As a result, fewer inflammatory signals are produced, and the protective lining of the gut stays intact, preventing harmful substances from leaking through and causing more damage.
Phytic acid enters intestinal epithelial cells and interacts with intracellular signaling components to inhibit upstream activation of AKT
Inhibition of AKT phosphorylation reduces activation of the IKK complex, preventing degradation of IκBα
Stabilized IκBα retains NF-κB p65 in the cytoplasm, blocking its nuclear translocation
Reduced nuclear NF-κB p65 decreases transcription of pro-inflammatory cytokines including IL-1β, IL-6, and TNF-α
Suppression of inflammation preserves expression of tight junction proteins (occludin, claudin-3, ZO-1) and mucin-2
Intact tight junctions and mucus layer limit bacterial translocation and prevent sustained immune activation in the intestinal tissue
