A NATO Advanced study Institute on "Receptors, Membrane Trans port and Signal Transduction," was held on the Island of Spet sai, Greece, from August 16-27, 1988, in order to consider re cent developments in membrane receptor research, membrane trans port and signal transduction mechanisms. These topics were put in the larger context of current knowledge on the structure and function of membranes; connections between different fields of research were established by in-depth dis cussions of energy transduction and transport mechanisms. The general principles of regulation by signal transduction...
