A NATO Advanced Study Institute on "New Developments in Lipid-Protein Interactions and Receptor Function" was held on the Island of Spetsai, Greece, from August 16-27, 1992. This Institute was organized to bring together researchers in the field of membrane organization and dynamics with those actively involved in studies on receptor function, signal transduction mechanisms and gene regulation. 2 Presentations and discussions focussed on the regulation of intracellular Ca +-levels, on the second messengers derived from inositol lipids and on the specific phospholipase C isozymes involved in...
