Modulatory effect of whey proteins in some cytokines involved in wound healing in male diabetic albino rats.

The anti-inflammatory cytokines (interleukin (IL)-4 and IL-10) and the pro-inflammatory cytokines (IL-1β, IL-6, and tumor necroses factor-alpha (TNF-α)) have important functions in wound healing. Thus, the aim of this study was to determine whether dietary supplementation with whey protein could enhance normal inflammatory responses during wound healing in diabetic rats. In this study, male albino rats were divided into a wounded control group, a wounded diabetic group, and a wounded diabetic group supplemented with whey protein orally at a dose of 100 mg/kg body weight. Tested rats showed increasing wound closure in rats treated with whey protein. In addition, after 4 days of wound, modulation in IL-4, IL-10, IL-1β, IL-6, and TNF-α levels were detected. Statistical analysis of data showed significant difference between the whey-protein-treated group and either control or diabetic groups (P < 0.05). Dietary supplementation with whey protein enhances the normal inflammatory responses during wound healing in diabetic rats by modulating the levels of some anti-inflammatory and inflammatory cytokines.
