In human right atria obtained from 21 patients during open-heart surgery, β-adrenoceptor
density [assessed by iodine-125-labeled (-)-cyanopindolol binding] and responsiveness
(positive inotropic responses to isoprenaline) were linearly related to the β-adrenoceptor
density in the corresponding circulating lymphocytes. This direct relation of human
myocardial and lymphocyte β-adrenoceptor alterations, therefore, makes it possible to
monitor drug-or disease-induced β-adrenoceptor changes in tissues not easily accessible in …
