Peter Riber Johnsen is a Postdoc in the Department of Veterinary and Animal Sciences at the University of Copenhagen, specializing in Preclinical Disease Biology. His research focuses on immunological mechanisms using Caenorhabditis elegans as a model organism and dendritic cell studies to investigate host-pathogen interactions, particularly with MRSA (methicillin-resistant Staphylococcus aureus).
Dr. Johnsen's research interests span immunology, microbiology, and nutritional science. His work examines how microbial metabolites, probiotics, and natural compounds affect immune responses, with particular focus on cytokine production in dendritic cells. He investigates antimicrobial properties of synthetic polyphenols, the role of S-layer structures in probiotic strains, and how food components influence immune cell function. His studies bridge basic immunological mechanisms with potential clinical applications in infectious disease and pediatric nutrition.
Analysis of his recent publications (2022-2025) reveals consistent methodology examining bacterial killing mechanisms, cytokine responses, and reactive oxygen species formation. His research demonstrates strong interdisciplinary connections between microbiology, immunology, and nutritional science, with increasing focus on pediatric applications in his more recent work.
Dr. Johnsen collaborates extensively with Professor Hanne Frøkiær and an international network of researchers across multiple institutions. His work has been published in reputable journals including Frontiers in Immunology, International Journal of Molecular Sciences, and Biomolecules. While specific grant information isn't detailed in the available text, his research output suggests active involvement in funded projects related to immunological mechanisms and host-pathogen interactions.
Based at Ridebanevej 9 in Frederiksberg, Dr. Johnsen is affiliated with the experimental animal models research group at the University of Copenhagen (https://ivh.ku.dk/forskning/exp_animal_models/), where he utilizes both in vitro (dendritic cell) and in vivo (C. elegans) models to address complex biological questions at the intersection of infection biology and immune regulation.
