Professor Ludger Johannes is Research Director (DRE) at INSERM. He is a member of the Studienstiftung des Deutschen Volkes (German organization of the academically gifted), Boehringer Ingelheim Fonds, European Molecular Biology Organization (EMBO), and German Academy of Science — Leopoldina. At Institut Curie, he has been heading since 2001 the Traffic, Signaling, and Delivery Team, member of the excellence initiative Cell(n)Scale. Since January 2014, he has directed the Cellular and Chemical Biology unit. His research aims at establishing fundamental concepts of endocytosis and intracellular trafficking. The Johannes team has discovered the membrane trafficking interface between early endosomes and the Golgi apparatus, and demonstrated that lectin-induced glycolipid reorganization acts as a driving force in clathrin-independent endocytosis (termed the GlycoLipid-Lectin / GL-Lect hypothesis). The studies of the Johannes team have been published in highly visible international journals, including Cell and Nature. Between 2014-2020, he was the holder of an ERC advanced grant. He also aims at exploiting the discoveries of his team for the development of innovative cancer therapy strategies using the B-subunit of Shiga toxin (STxB) as a "pilot" for the delivery of therapeutic compounds to precise intracellular locations of dendritic cells for immunotherapy, and to tumors for targeted therapy.
