Ludger Johannes


Ludger Johannes is a French-German biochemist who has specialized in the field of endocytosis and intracellular trafficking. He and his team study how sugars attached to proteins or lipids influence the transport of biological material into eukaryotic cells.
Johannes is research director “classe exceptionnelle” at the Institut Nationale de la Santé et de la Recherche Médicale at Institut Curie in Paris, France. He is an elected member of the European Molecular Biology Organization, and German Academy of Sciences Leopoldina and an alumnus of the Germany-based Boehringer Ingelheim Fonds – Foundation for Basic Research in Medicine and the German Academic Scholarship Foundation Studienstiftung des deutschen Volkes.

Education

During his undergraduate biochemistry studies at the University of Bayreuth, Germany, Ludger Johannes spent 1 year from 1990 to 1991 in the team of Heinz Arnheiter at the National Institutes of Health in Bethesda, USA. In February 1993, he earned his diploma in biochemistry. He started his PhD work in March 1993 under François Darchen at the Institut de biologie physico-chimique in Paris, France. After the PhD viva in October 1995, he moved to Institut Curie in Paris to the team of Bruno Goud, where he worked as a post-doctoral fellow until 1997. In 2001, he received the habilitation to direct research,.

Professional experience

Johannes joined INSERM 1997 as a staff scientist. In 2001, he became team leader in its Compartmentalization and Cellular Dynamics unit, and in 2014 the director of the Cellular and Chemical Biology unit at Institut Curie.
He served 4 years as a member of the bureau of study section 23 of CNRS for the recruitment of staff scientists and the evaluation of researchers and research units, and 4 years on the equivalent commission CSS3 of INSERM. He served on international review boards, including the Human Frontier Science Program (HFSP) Organization fellowship committee. He obtained national, European and intercontinental grant support, including an Advanced Grant of the European Research Council and 2 Human Frontier Science Program grants.
In the past Johannes created 2 biotech companies: ShigaMediX and STxB Pharma Technologies.

Research

Johannes’ research aims at establishing fundamental concepts of endocytosis and intracellular trafficking. His team has made two major contributions in this context: the discovery of a membrane trafficking interface between early endosomes and the Golgi apparatus, and the demonstration that dynamic lectin-induced glycosphingolipid reorganization acts as a driving force for endocytic pit construction in clathrin-independent endocytosis. He also aims at exploiting his discoveries in fundamental membrane biology research for the development of cancer therapy strategies. His team has validated the B-subunit of Shiga toxin as a "pilot" for the delivery of therapeutic compounds to precise intracellular locations of dendritic cells for immunotherapy, and tumors for targeted therapy
