In step with the rapid growth of research into the biochemical and functional characterization of the endosome, Volume 19 surveys the recent advances in the methodological aspects of this field. Coverage includes the use of free flow electrophoresis to define endosome subpopulations, the endosomal compartments in rat hepatocytes, the role of endosomes in transmembrane signalling, and six additional articles.
(Director: Pierre J. COURTOY) Two years after its first gathering in Oeiras, Portugal, the European Endocytosis Group convened for a second workshop at the Pasteur Institute, Paris, on October 1-5, 1990. The meeting is reported in detail in this volume; a preliminary coverage, based on the overviews of each session, has appeared in the New Biologist (1991, 3:243-252). The three main objectives, to broaden the audience, to present a more comprehensive view of the multiple aspects of endocytosis, from basic biology to health, disease and therapy, as well as to clarify controversial issues, have been largely fulfilled. The Second European Workshop on Endocytosis was attended by more than tOO participants, originating from 18 countries. 59 lectures and 35 posters were presented. In addition, vivi~ roundtables allowed to thoroughly discuss the dynamics and the regulation of the endocytic apparatus, as well as the role of endocytosis in antigen presentation. Endocytosis is a general and distinctive property of all eukaryotic cells, including protists, plants and fungi.
Many hormones, growth factors, and other large molecules bind to speci Jic receptors on the surface of eukaryotic cells and are rapidly taken into these cells. Current techniques of protein purification have made available sufficient amounts of these molecules so that detailed studies of their interaction with cells could be carried out. These studies have been performed on just a few types of cells, but it is clear that all types of cells carry out a_ similar internalization process. The realization that cells rapidly internalize hormones, growth factors, transport proteins, toxins, and viruses has led many investigators to address a similar series of questions: (1) What is the pathway by w...
