BACKGROUND AND AIMS: The natural immunomodulator, lactoferrin, is widespread among various biological fluids and is known to exert an anti-inflammatory effect. However, there has been only one study that examined the mode of action of lactoferrin in reducing intestinal damage. We investigated the therapeutic role of lactoferrin and its effect on the levels of pro-inflammatory and anti-inflammatory cytokines, by using a rat model of dextran sulfate sodium (DSS) induced-colitis. METHODS: Male Sprague-Dawley rats were given distilled drinking water containing 2.5% (wt/vol) synthetic DSS ad libitum. Bovine lactoferrin was given once daily through gavage, starting 3 days before beginning the DSS administration, until death. The whole colon was removed to be examined macroscopically and histologically. Myeloperoxidase activity, and pro-inflammatory and anti-inflammatory cytokines in the colonic tissue were also measured. RESULTS: Dextran sulfate sodium-induced colitis was attenuated by oral administration of lactoferrin in a dose-dependent manner, as reflected by improvement in clinical disease activity index, white blood cell count and hemoglobin concentration, macroscopic and histological scores, and myeloperoxidase activity. Reduced inflammation in response to lactoferrin was correlated with the significant induction of the anti-inflammatory cytokines, interleukin-4 and interleukin-10, and with significant reductions in the pro-inflammatory cytokines, tumor necrosis factor alpha, interleukin-1beta, and interleukin-6. CONCLUSIONS: We concluded that oral administration of lactoferrin exerts a protective effect against the development of colitis in rats via modulation of the immune system and correction of cytokine imbalance. Lactoferrin has potential as a new therapeutic agent for inflammatory bowel disease.
