(19) We demonstrate here the specific and saturable labeling of a population of larval receptors with the GABA analog beta-(p-chlorophenyl)-[3H]GABA ([3H]baclofen); identification of these labeled receptors with those controlling metamorphosis is suggested by four independent criteria: the effectiveness of GABA and its close structural analogs to induce metamorphosis is closely correlated with the effectiveness of these compounds to compete for binding to this receptor; the natural inducer purified from the recruiting algae competes for binding to this receptor; (-)-[3H]baclofen specifically bound to the receptors is shed from the larvae after approximately 20 hr, at the time corresponding to the metamorphic abscission and shedding of sensory cilia and other structures from the larvae; and the availability of the receptors for labeling and the ability of the larvae to respond to GABA and GABA analogs can be down-regulated in parallel by habituation of the larvae early in their development.
(20) The apparent threshold for AVP release (defined as the abscissal intercept of the regression line relating plasma AVP [PAVP] to Posmol) was also decreased significantly throughout gestation, as was the osmotic threshold for thirst (derived from analogue scales relating desire to drink to Posmol).
