Die GABAA-Rezeptor-Familie

ABTRACT: Clinically used anesthetics show amnestic, sedative, hypnotic and immobilizing properties. On a molecular level these drugs affect several receptors in the cell membrane of neurons. By using genetically engineered mice a linkage can now be made between actions on certain receptors and clinically desired and undesired effects. Experiments show that a certain GABA(A) receptor subtype mediates hypnosis and immobility, whereas another subtype is involved in side-effects like sedation and hypothermia. These findings form the basis for the development of new drugs, acting highly specific and with fewer side-effects.
