Efeito anti-inflamatório de proteínas sacietogênicas da semente de tamarindo em modelo experimental de síndrome metabólica

Abstract

Trypsin inhibitors are studied in a variety of models for their anti-obesity and anti-inflammatory bioactive properties. Our group has previously demonstrated the satietogenic effect of tamarind seed trypsin inhibitors (TTI) in eutrophic mouse models and anti-inflammatory effects of other trypsin inhibitors. In this study, we evaluated TTI effect upon satiety, biochemical and inflammatory parameters in an experimental model of metabolic syndrome (MetS). Three groups of n=5 male Wistar rats with obesity-based MetS received for 10 days one of the following: 1) Cafeteria diet; 2) Cafeteria diet + TTI (25 mg/Kg); 3) Standard diet. TTI reduced food intake in animals with MetS. Nevertheless, weight gain was not different between studied groups. Dyslipidemia parameters were not different with the use of TTI, only the group receiving standard diet showed lower VLDL and triglycerides (TG) (Kruskal-Wallis, p < 0.05). IL-6 production did not differ between groups. Interestingly, TNF-α was lower in animals receiving TTI. Our results corroborate the satietogenic effect of TTI in a MetS model. Furthermore, we show that TTI used with a cafeteria diet may decrease inflammation regardless of weight loss. This puts TTI as a candidate for studies to test its effectiveness as an adjuvant in MetS treatment.
