Objective (s):

Zonula occludens proteins (ZO-1 and ZO-2) are important intracellular tight junction (TJ)-associated proteins that link the cell cytoskeleton to the trans-membrane TJ proteins. Destruction of TJ proteins is called the “leaky gut syndrome” and has been observed in some of the gastrointestinal diseases such as the inflammatory bowel disease (IBD). So, therapeutic approaches aim to restore the expression of TJ proteins and reduce intestinal permeability. Healing effect of Kombucha tea (KT), so-called long-life mushroom, on the gastrointestinal system, particularly its extraordinary healing effects on intestinal ulcers has been purported traditionally and rarely reported scientifically. This study aimed to investigate the therapeutic effect of filtered KT (fKT) in young and old mice model of colitis.

Materials and Methods:

Leaky gut was induced in two groups of young and old age using dextran sodium sulfate in …
