European Lipoprotein Club: report of the 20th annual conference, Tutzing, 8-11 September 1997.

ABSTRACT

The year 1997 celebrated the 20th anniversary of the European Lipoprotein Club. Sessions explored topics in the line of classical concepts and forthcoming advances in the field of basic and clinical research on lipoproteins. Participants from 18 European countries attended the conference. Recent Developments in Lipoprotein Research, were reviewed by Thomas Olivecrona (Umea, Sweden), who gave a perspective on lipolysis; and Gerd Assmann (Münster, Germany), who overviewed epidemiological data of the PROCAM study and focused on the biochemical and genetic components of reverse cholesterol transport. Session I, chaired by Katriina Aalto Setälä (Tampere, Finland) and Marten Hofker (Leiden, Netherlands) was dedicated to 'Lipoprotein receptors (old and new)'. Various structural and functional aspects were reported for the newcomers in the ever enriching LDL receptor gene family (VLDLR, LR7/8B, LR11, Megalin, RAP-related proteins). However, a decade of identification of LDL receptors gene defects reveals now that phenocopies of familial hypercholesterolemia may be linked to a third, yet unknown locus. Identification of pathways which clear HDL is underway. Session II, chaired by David Bowyer (Cambridge, United Kingdom) and Richard W James (Geneva, Switzerland), was entitled 'Significance of lipoprotein heterogeneity (metabolic and pathological aspects)'. Factors involved in lipoprotein modification (dense LDL, oxidation), transient production (post prandial, VLDL synthesis) or degradation (complement activation) and controversial hypotheses on their links with atherosclerosis were discussed. Session III on 'Novel methodologies for lipoprotein research' was chaired by Rudolph Poledne (Prague, Czech Republic) and Armin Steinmetz (Marburg, Germany). Simple technologies for routine assessment of lipoprotein metabolism, as well as the most sophisticated ones, to study lipid and free radical exchanges between particles, were presented.
