معرفی
Univ.-Prof. Dr. med. Martin A. Kriegel serves as full Professor and Department Head of the Department of Translational Rheumatology and Immunology at the Institute of Musculoskeletal Medicine, University of Münster, while maintaining an active laboratory at Yale School of Medicine. He leads the Section for Rheumatology and Clinical Immunology (SRKI) at Medical Clinic D, where his team integrates clinical care with cutting-edge microbiome research. His department operates from Röntgenstraße 21 and Von-Esmarch-Str. 54 in Münster, Germany, with extensive collaborations including the "Cells in Motion" research initiative and the CiM-IMPRS graduate program.
Dr. Kriegel's research program focuses on the critical interface between host immunity and microbiota, particularly investigating how gut commensals translocate to host tissues and trigger autoimmune responses. His laboratory pioneered the discovery that specific pathobionts like Enterococcus gallinarum and certain Lactobacillus strains can translocate from the gut to mesenteric lymph nodes, liver, and other sites, driving autoimmune responses through molecular mimicry of human autoantigens. His work has established fundamental mechanisms by which microbiota influence rheumatic diseases, cutaneous autoimmunity, and cancer immunology, with particular emphasis on Ro60 autoantigen mimicry, TLR7-dependent pathways, and diet-microbiome interactions. The laboratory employs advanced techniques including gnotobiotic mouse models, humanized systems, and detailed molecular characterization of host-pathobiont interactions.
Analysis of Dr. Kriegel's publication record reveals a consistent trajectory of high-impact research connecting microbiome dynamics to autoimmune pathogenesis. His most recent work (2023-2025) demonstrates increasingly sophisticated understanding of how specific bacterial strains influence disease phenotypes across multiple autoimmune conditions, with notable advances in identifying shared microbiome signatures across lupus and inflammatory bowel disease. The publications show progressive refinement from initial observations of microbial translocation to detailed mechanistic insights into tryptophan catabolism pathways, structural basis of molecular mimicry, and diet-sensitive microbial triggers.
Dr. Kriegel's scientific recognition includes US Patent No. 11,058,756 B2 for compositions treating autoimmune diseases by reducing enterococcus, reflecting the translational potential of his research. His laboratory receives substantial funding, most notably a $3 million award from the Lupus Research Alliance for the TransLuMi project investigating gut pathobiont translocation in systemic lupus erythematosus.
As an educator and mentor, Dr. Kriegel directs a substantial research team including multiple postdocs (Drs. Marcia Pereira, Nathalie Becker), PhD candidates (Anna Brinkhege, Carina Brune, Helen Fuhrmann), and laboratory specialists. He participates in the CiM-IMPRS graduate program and supervises medical students through the MedK program. His laboratory currently manages multiple significant research projects including: (A) intestinal wall permeability and pathobiont translocation in autoimmunity; (B) diet-environment-microbiome interactions; (C) microbiota disruption of immunological tolerance; and (D) microbiome roles in lymphoma development.
The Kriegel laboratory maintains state-of-the-art facilities at both Münster and Yale, with specialized capabilities in gnotobiotic research, microbiome analysis, and immune profiling. His team collaborates with international partners including Dr. Eran Elinav at Weizmann Institute, Dr. Nissan Yissachar at Bar-Ilan University, Prof. George Tsokos at Harvard, and Prof. Ilana Brito at Cornell University.
