identified so far, only β4 mRNA is expressed in all brain regions examined [37]. Although mRNA coding for β2 or β3 subunits have been reported in both the brain and smooth muscle, to date there is no evidence that they are expressed and associated with the α subunit in neurons. Finally, the β1 subunit is found in both neurons and smooth muscle cells [9,38].
