Abstract

The maintenance of the endothelial function, challenged by oxidative stress and inflammation, is a fundamental target of preventive dietary strategies. The aim of this study was to investigate the protective activities of a wheat peptide belonging to the family of the "non-specific lipid transfer protein type 2" (nsLTP2). Results showed that HUVECs pretreatment with nsLTP2 significantly decreased both oxidative stress and cell damage induced by inflammation, and significantly counteracted the increased expression of adhesion molecules (VCAM-1, ICAM-1, E-selectin). Moreover, nsLTP2 increased the expression of HO-1, similarly to statins. As HO-1 has been shown to ameliorate inflammation in part through its ability to inhibit expression of endothelial adhesion molecules, experiments were also conducted using two HO-1 inhibitors, showing that the induced expression of HO-1 contributes to the anti-inflammatory activity exerted by nsLTP2. Taken together, obtained results suggest a nutraceutical role played by nsLTP2 in maintaining vascular health.
