It is often said that we are what we eat. Understanding how diet can affect physiology is my main research interest. To study the mechanisms by which diets modulate the function of the gastrointestinal tract, in my lab we use in vitro and in vivo models. Our in vivo models are based on feeding animals with different diets, nutritional supplements or novel feed ingredients to evaluate how this nutritional manipulations change the epithelial cell composition, the local immune response, the expression of nutrient sensing molecules, and hormone secretion of the intestine. We also use cell lines and enteroids (“mini-guts”) as in vitro models to understand the mechanisms of action of specific nutrients, and as a model to study bacterial infections of the intestine. I believe that understanding the effects that nutrients have on the function of the intestine will help us design better and healthier diets to improve human and animal lives.
Ongoing studies in my laboratory include:
- Effect of dietary fiber on intestinal cell differentiation and digestive function
- Effect of high fiber diets on the local intestinal immune response
- Effects of organic and inorganic zinc sources on the intestinal epithelium
- Effects of viscosity on nutrient digestibility, intestinal cell differentiation, mucin production, and endogenous losses of threonine of pigs
- Use of swine enteroids as in vitro model of normal and pathological gastrointestinal physiology
- Use of enteroids to defining the mechanisms of Lawsonia intracellularis pathogenesis
