(author), Nieuwdorp, M. (author), IJzerman, R.G. (author)Expert groups argue to raise the recommended daily allowance for protein in older adults from 0.8 to 1.2 g/kg/day to prevent undernutrition. However, protein is thought to increase satiety, possibly through effects on gut microbiota and central appetite regulation. If true, raising daily protein intake may work counterproductively. In a...article 2023

(author), Masereeuw, R. (author), Bobeldijk-Pastorova, I. (author), Nooijen, I. (author), van de Steeg, E. (author)The majority of intestinal in vitro screening models use cell lines that do not reflect the complexity of the human intestinal tract and hence often fail to accurately predict intestinal drug absorption. Tissue explants have intact intestinal architecture and cell type diversity, but show short viability in static conditions. Here, we present a...article 2022

(author), Hakvoort, T.B.M. (author), de Jonge, W.J. (author), Heinsbroek, S.E.M. (author)β-glucan consumption is known for its beneficial health effects, but the mode of action is unclear. While humans and mice lack the required enzymes to digest β-glucans, certain intestinal microbes can digest β-glucans, triggering gut microbial changes. Curdlan, a particulate β-glucan isolated from Alcaligenes faecalis, is used as a food additive...article 2021

Donkers, J.M. (author), Eslami Amirabadi, H. (author), van de Steeg, E. (author)Over the past decade, microfluidic intestine-on-a-chip models have been emerging as a novel platform to study intestinal function in health and disease. These microphysiological systems surpass conventional in vitro intestinal model systems, as they add microenvironmental context in the form of mechanical cues or by the incorporation of multiple...article 2021

(author)Over the past years, several preclinical in vitro and ex vivo models have been developed that helped to understand some of the critical aspects of intestinal functions in health and disease such as inflammatory bowel disease (IBD). However, the translation to the human in vivo situation remains problematic. The main reason for this is that these...article 2021
