La permeabilidad intestinal, una bioactividad diana de los polifenoles del vino por explorar

Abstract

[ES] El vino forma parte del grupo de alimentos cuya relación con la salud humana se ha estudiado más ampliamente debido a su alto contenido y diversidad en polifenoles, sin embargo, los estudios sobre sus efectos en la función intestinal son relativamente escasos. Una de las principales propiedades de la barrera intestinal es lo que se define como permeabilidad intestinal (PI), que permite o restringe selectivamente el intercambio de agua, iones y macromoléculas entre la luz intestinal y los tejidos subyacentes. La alteración de la barrera intestinal da lugar a lo que se conoce como "intestino permeable" y se ha relacionado con procesos de inflamación y disfunción intestinal. La integridad entre las células epiteliales está garantizada por la existencia de numerosas uniones estrechas (TJ) en las que intervienen varias familias de proteínas, como las ocludinas, las claudinas, las moléculas de adhesión de unión y las proteínas de placa. Recientes estudios in vitro han evidenciado efectos prometedores de los polifenoles del vino sobre la permeabilidad paracelular y la expresión de las proteínas TJ en células HT-29. Sin embargo, para estos experimentos in vitro, los extractos de polifenoles del vino se utilizaron directamente sin digestión intestinal previa, por lo que son de interés experimentos en condiciones fisiológicas con los metabolitos resultantes del paso de los polifenoles a través del tracto gastrointestinal.

[EN] Wine has been one of the foods whose relationship with human health has been most extensively studied due to its high content and diversity in polyphenols; however, studies on its effects on the intestinal function are relatively scarce. One of the main properties of the intestinal barrier is what is defined as intestinal permeability (IP), which selectively allows or restricts the exchange of water, ions, and macromolecules between the intestinal lumen and the underlying tissues. The disruption of the intestinal barrier results in what is known as "leaky gut" and has been related to inflammation processes and intestinal dysfunction. The integrity between epithelial cells is ensured by the existence of many tight junctions (TJ) which involve several protein families, including occludins, claudins, junctional adhesion molecules, and plaque proteins. Recent in vitro studies have evidenced promising effects of wine polyphenols on paracellular permeability and TJ protein expression in HT-29 cells (Nunes et al., 2019). However, for these in vitro experiments, wine polyphenols extracts were used directly without previous intestinal digestion, so further experiments considering the metabolites resulting from the passage of polyphenols through the gastrointestinal tract are of interest.
