We adapted a technique for isolation of mononuclear leukocyte (MNL) subsets with immunomagnetic beads to the study of beta-adrenergic receptors. Mixed MNL cells were sequentially incubated with monoclonal antibodies specific for certain MNL subsets. Sheep antimouse antibodies coupled to magnetic beads were then added, and the desired MNL subset was pulled out with a magnet. This method yielded subsets with high purity and did not alter beta-receptor density or function. Healthy volunteers were treated for 7 days with the beta 2-selective agonist terbutaline (5 mg t.i.d.). Terbutaline treatment decreased beta-receptor number and isoproterenol-stimulated cyclic adenosine monophosphate (cAMP) generation in natural killer cells, helper T cells, and suppressor/cytotoxic T cells but not in B cells. The decrease was greatest in suppressor/cytotoxic T cells and least in helper T cells. Thus beta-adrenergic receptor regulation by agonists appears to differ among MNL subsets.
