WELCOME

Welcome to the van Pijkeren Laboratory!

We work at the interface of industry and medicine. While we have completed projects with various lactic acid bacteria, most of our research focuses on Limosilactobacillus reuteri, until recently known as Lactobacillus reuteri. L. reuteri is an important gut symbiont, and select strains have demonstrated health-promoting, i.e., probiotic, properties. The ultimate goal of our research program is to understand probiotic mechanisms towards the development of next-generation probiotics.

For many years, we have invested in developing genetic tools for use in L. reuteri and other lactic acid bacteria. As a consequence, our laboratory is at the forefront of lactic acid bacteria genome editing. These genome editing tools place us in the exciting position to pursue research in the following areas:

(1) to unravel the molecular underpinnings by which probiotic bacteria interact with the vertebrate host;
(2) to unravel the tripartite interplay between diet, a probiotic, and its bacteriophages;
(3) to develop probiotic bacteria as therapeutic delivery vehicles.

We’re grateful for our current and past funding, which, combined with great collaborators, made it possible to build a dynamic team of staff and students to drive our research.

If you are interested in learning more about our work, please don’t hesitate to contact us.
