The metabotropic glutamate 1 (mGlu(1)) receptor in cerebellar Purkinje cells plays a key role in motor learning and motor coordination. Here we show that the G protein-coupled receptor kinases (GRK) 2 and 4, which are expressed in these cells, regulate the mGlu(1) receptor by at least in part different mechanisms. Using kinase-dead mutants in HEK293 cells, we found that GRK4, but not GRK2, need...
We have measured the plasma levels of salbutamol, terbutaline and theophylline in 140 patients (70 men, mean age 57 yrs) arriving for emergency treatment with severe acute asthma. The aim of the study was to investigate how the measured plasma levels correlated with the reported bronchodilator intake and whether the pretreatment beta 2-agonist levels influenced the effect of emergency salbutamo...
Interspecies differences in the cardiac negative inotropic effects of beta(3)-adrenoceptor agonists.
The aim of the present study was to compare the effects of three preferential (BRL 37344, SR 58611, CL 316 243) and a partial (CGP 12177) beta-adrenoceptor (beta(3)-AR) agonists on the contractility of ventricular strips sampled from various mammalian species including humans. In the human heart, all beta(3)-AR agonists tested decreased contractility by 40 to 60% below control with an order of ...
1. The pharmacological features of rat white adipocyte beta-adrenoceptor subtypes were investigated by saturation and beta-agonist competition studies with [3H]-CGP 12177 and by lipolysis induced by beta-agonists as well as their inhibition by CGP 20712A (selective beta 1-antagonist) and ICI 118551 (selective beta 2-antagonist) in an attempt to establish a relationship between the functionality...
