Jonathan D. Kaunitz MD, FACG, FAPS, AGAF
Dr. Jonathan D. Kaunitz is a distinguished researcher and clinician whose work has significantly advanced our understanding of gastrointestinal physiology and pathology.
Dr. Kaunitz’s primary research interests include:
- Intestinal Transport of Endotoxin and Small Molecules: Dr. Kaunitz investigates the mechanisms by which endotoxins and other small molecules are transported across the intestinal barrier. This research is crucial for developing therapies to prevent and treat infections and inflammatory diseases of the gut.
- Gut Barrier Function: Understanding the integrity and function of the gut barrier is essential in preventing diseases such as inflammatory bowel disease (IBD) and other gastrointestinal disorders. Dr. Kaunitz's work focuses on the factors that maintain and disrupt this critical barrier.
- Clinical Aspects of Iron Deficiency: Iron deficiency is a common clinical problem that can lead to significant health issues. Dr. Kaunitz explores the underlying causes and clinical manifestations of iron deficiency, aiming to improve diagnostic and therapeutic approaches.
- Epithelial DUOX-Halide-Peroxidase System: This system plays a key role in the body's defense against microbial infections. Dr. Kaunitz's research delves into the functioning and regulation of this system, with implications for understanding and treating various gastrointestinal diseases.
