Involvement of 5-HT(3) receptors in the nucleus accumbens in the potentiation of cocaine-induced behaviours in the rat.

abstract：:Two splice isoforms of rabbit alpha(1a)-adrenergic receptor (AR), (named alpha(1a)-OCU.2-AR and alpha(1a)-OCU.3-AR) have been isolated from the liver cDNA library in addition to the previously reported isoform (alpha(1a)-OCU.1-AR). Although they have the identical splice position with human alpha(1a)-AR isoforms, the ...
