Differential localization of 5-HT1A and 5-HT1B receptors in MDCK II cells To study the sorting properties of 5-HT1A and 5-HT1B receptors in MDCK II cells, we compared the distribution of these receptors to that of the alpha 2A adrenergic receptors (α2A-AR). We used α2A-AR as a control because this r ...
