| Research Abstract |
This research group was organized by the aim of (1) analyzing mechanisms of action of new neurotransmitters on receptors and regulations of receptor function in the brain and peripheral organs and tissues by the use of advanced experimental technique and (2) introducing new concepts of interaction between agonists, receptors, signal-transduction processes and cellular responses.
The members of this group carried out their study with the brain, heart, blood vessel, extravascular smooth muscle and cultured cells in vitro and in vivo in various animal species, including rhdents, dogs and monkeys. we discussed with great interests on (1) problems of contrasting of different signal transduction and cellular responses mediated by the same receptor subtypes in the brain and peripheral tissues, (2) physiological roles and pathophysiological implications of recently-determined new nerves in which NO acts as neurotransmitter, (3) some of the so-called selective antagonists of receptor subtypes that are effective only in certain animals species, (4) new mechanisms of agonist action through classic receptor activation that are proposed from findings obtained by advanced technique of analysis, and (5) newly-found receptor-G-protein-second messenger systems. I believe that through the discussion, exchange of ideas and presentation of new findings in this group activity, each of the members greatly contributed to the progress of receptor research and in addition obtained valuable fruits from presentations by others for the future study and broadened the knowledge of receptor characteristics.
