Abstract
Abnormal autonomic nervous system responsiveness may contribute to the pathogenesis of asthma and other allergic diseases. Therefore, we measured alpha- and beta-adrenergic and cholinergic responsiveness in allergic subjects. Allergic asthmatic subjects had an abnormal adrenergic (alpha = hyperresponsive; beta = hyporesponsive) and cholinergic (hyperresponsive) profile. However, subjects with allergic rhinitis and preallergic subjects (those with positive allergen skin tests without any disease manifestation) had equivalent beta-adrenergic and cholinergic abnormalities. Thus, all allergic subjects showed abnormal beta-adrenergic hyporeactivity and cholinergic hypersensitivity whereas allergic asthma was singularly associated with excessive alpha-adrenergic responsiveness. Autoantibodies against beta-receptors were found predominantly in subjects with beta-adrenergic hyporeactivity. The presence of these autoantibodies and the physiologic abnormalities associated with their presence suggests a causitive relationship.

Abstract
We identified autoantibodies to beta 2-adrenergic receptors in the plasma of three apparently normal subjects, four patients with allergic asthma, one subject who was "preallergic" (at risk of allergy), and one patient with cystic fibrosis. Although these antibodies appeared to be heterogeneous, they shared the ability to affect binding of [125]protein A to calf-lung membranes, to inhibit beta-adrenergic ligand binding to calf-lung bet-adrenergic receptors, and to precipitate solubilized calf-lung beta-adrenergic receptors in an indirect immunoprecipitation assay. The presence of autoantibodies to beta-adrenergic receptors in these subjects correlates with abnormal autonomic responsiveness characterized by alpha-adrenergic and cholinergic hypersensitivity and beta-adrenergic hyposensitivity. These findings suggest that autoantibodies to beta-adrenergic receptors may play a part in the development of ment of autonomic abnormalities.

Abstract
We have developed four hybridomas that produce monoclonal antibodies to the turkey erythrocyte beta 1-adrenergic receptor and one hybridoma that produces a monoclonal antibody to the calf lung beta 2 receptor. Splenic lymphocytes from BALB/c mice immunized with partially purified turkey erythrocyte beta 1 receptors or calf lung beta 2 receptors were used with the mouse myeloma line SP2/O-Ag14 to yield hybridoma cultures producing beta receptor monoclonal antibodies of the IgG class. The anti-turkey erythrocyte beta receptor antibodies precipitated partially purified beta receptors and inhibited adrenergic ligand binding. In contrast to autoantibodies to beta 2-adrenergic receptors [Venter, J. C., Fraser, C. M. & Harrison, L. C. (1980) Science 207, 1361-1363] which do not crossreact with cardiac beta 1 receptors, monoclonal antibody FV-104 directed against the adrenergic ligand binding site of turkey erythrocyte beta receptors crossreacted equally with calf liver and lung beta 2 receptors as well as calf heart beta 1 receptors. These data suggest that some molecular homology exists between beta-adrenergic receptors of substantially diverse pharmacological classes. We utilized the monoclonal antibodies in the final stage of turkey erythrocyte beta 1 receptor purification. Turkey erythrocyte beta receptors eluted from FV-104 monoclonal antibody affinity columns with Na-DodSO4 appeared as three components of Mr 70,000, 31,000, and 22,000 on NaDodSO4/polyacrylamide gels. Iodination of material eluted from immunoaffinity columns with propranolol demonstrated the existence of only a single component (Mr, 70,000), indicating that the turkey erythrocyte beta 1 receptor can be purified to homogeneity.

Abstract
Digitonin-solubilized turkey erythrocyte beta-adrenergic receptors were reconstituted by dialysis into human erythrocyte acceptor membranes which lack beta receptors. Incorporation of turkey beta receptors into acceptor membranes was directly proportional to the quantity of soluble protein added to the reconstitution system. Reconstituted beta receptors demonstrate saturable [125I]iodohydroxybenzylpindolol binding (Bmax = 11.1 +/- 0.8 fmol/mg, K = 77.8 +/- 8.6 pM) and stereospecificity ((-)-propranolol, K = 11.0 nM; (+)-propranolol, K = 2000 nM; (-)-isoproterenol, K = 250 nM; (+)-isoproterenol, K = 82 micro M). Reconstituted beta receptors appear to be incorporated into acceptor membranes as integral proteins. Reconstituted beta receptors cannot be extracted by high salt or pH (3 to 11); detergent is required for resolubilization of reconstituted beta receptors. Adenylate cyclase stimulation was not obtained in reconstituted membranes since acceptor membranes lack a catalytic subunit. However, guanine nucleotide regulation of agonist affinity was observed indicating a functional reconstitution. GTP (100 micro M) produces a 5-fold decrease in the affinity of isoproterenol for reconstituted beta receptors. Experiments with sulfhydryl reagents indicate that the reconstituted beta receptor couples with the guanine nucleotide regulatory protein of the acceptor membranes. These data describe the successful reconstitution of a beta receptor and indicate that the reconstituted beta receptor can interact with the GTP binding protein of human erythrocyte acceptor membranes.

Abstract
Autoantibodies to beta 2-adrenergic receptors have been identified in the serum of one patient with allergic rhinitis ("hay fever") and two patients with asthma. The antibodies precipitate solubilized dog lung beta receptors in an indirect immunoprecipitation assay and inhibit the specific binding of iodine-125-labeled iodohydroxybenzylpindolol to membrane-associated receptors from dog lung, calf lung, and human placenta. Ligand binding to canine heart beta 1 receptors is not affected by the antibodies.

Abstract
Isoproterenol, corticotropin (ACTH), and triodothyronine immobilized on glass and Sepharose beads by diazotization procedures have been shown to interact with cultured tumor cells of "target tissue" origin. Cells used were rat glioma cells (C6), rat adrenal tumor cells (Y-1), and rat pituitary tumor cells (GH3). The rat glioma cells bound principally to immobilized isoproterenol, whereas the rat adrenal tumor cells bound to immobilized corticotropin, and rat pituitary tumor cells bound to immobilized triiodothyronine. Binding was inhibited by preincubation of the cells in soluble drug or hormone. With C6 cells there was a positive correlation between adenylate cyclase [ATP pyrophosphate-lyase (cyclizing, EC 4.6.1.1] stimulation and the degree of binding to the immobilized isoproterenol. Norepinephrine, bound through the ethanolamine side chain via an amide linkage, did not bind cells, demonstrating specific structural requirements for drug-cell interactions. HeLa cells were shown to bind tightly to diphtheria toxin coupled to Sepharose beads via an amide bond. This binding was inhibited by prior incubation of the Sepharose toxin with purified antitoxin. Toxin bound to Sepharose via an azo bond did not bind cells. These data suggest that the cell affinities are due to cell surface receptors interacting with the immobilized drugs and hormones, and that the observed affinities possibly reflect the relative receptor complement of these cells.

Abstract
A cell line from the intima of the rabbit aorta has been established. This cell line exhibits strict contact inhibition, and morphologically resembles intimal endothelial cells. B-type blood group antigens and the presence of fibrinolytic activity also distinguish these cells from smooth muscle cells and from fibroblasts of the aortic wall. Endothelial cells were assayed for changes in levels of adenosine 3':5'-cyclic monophosphate (cAMP) and guanosine 3':5'-cyclic monophosphate (cGMP) in response to a series of vasoactive drugs. Control levels for cAMP and cGMP are 7.01 +/- 0.82 and 1.50 +/- 0.06, respectively (mean +/- SEM). Norepinephrine, acetylcholine, 5-hydroxytryptamine, and phenylephrine increased the levels of both nucleotides significantly. Propranolol (10-5 M) and phentolamine (10-5M) inhibited, respectively, the cAMP and cGMP response to norepinephrine. Angiotensin II and histamine significantly increased cGMP levels but not cAMP levels of the endothelial cells. The cGMP increases with acetylcholine were inhibited by atropine. These results indicate that the established cell line is endothelial in nature and contains cellular receptors to a variety of vasoactive agents.

Abstract
l-Isoproterenol was covalently coupled via an azo linkage to soluble copolypeptides of molecular weight 1500 and 10,000 containing an aromatic amine. The polymeric azo-isoproterenol derivatives were purified by gel chromatography which reduced contamination by the parent isoproterenol to undetectable levels (i.e., less than 0.01%) and by 6-aminoisoproterenol to less than 0.4%. Both polymeric isoproterenol derivatives were found to elicit positive chronotropic responses in isolated perfused guinea pig hearts. The mean effective doses (ED50S) for the 1500 and 10,000 molecular weight derivatives were within 1.3 and 2.0 orders of magnitude, respectively, of the ED50 of l-isoproterenol. The responses cannot be attributed to free isoproterenol because this drug could not be detected in our preparations. Neither can the observed biological activity be attributed to 6-aminoisoproterenol, since this compound's dose-response is shifted 3 orders of magnitude to the right of l-isoproterenol and 1-2 orders of magnitude to the right of the polymeric derivatives. Inotropic response decay times in isolated cat papillary muscles following washouts indicate that the polymer-bound drug does not diffuse into the muscle tissues. We feel that our findings demonstrate that under controlled conditions the catecholamines can retain biological activity while covalently bound to a polymeric support.

Abstract
Isoproterenol, norepinephrine, and epinephrine covalently bound to glass beads exert a positive inotropic effect on isometrically contracting papillary muscles from cats. Immobilized isoproterenol maintains increases in force and velocity of contraction for more than 5 hr. 1 muM Cocaine potentiates the action of immobilized norepinephrine, isoproterenol, and epinephrine, but not of isoproterenol in solution. The data presented indicate that the effects of immobilized catecholamines are not due to their coming off the glass. The effects observed with cocaine and immobilized catecholamines are not altered by prior treatment of the muscle with reserpine. These results suggest that the major site of catecholamine action is on receptors located on the extended surface of myocardial cells and a post-junctional site for cocaine potentiation.

Abstract
Catecholamines bound covalently to glass beads have been found to have biological activity in several systems. Experimental evidence has been found that immobilized epinephrine and isoproterenol accelerate the heart rate in dogs, chick embryo, and chick heart cells grown in culture, whereas immobilized propranolol results in a decrease in heart rate. Isoproterenol bound to glass beads has also been shown to markedly increase the level of adenosine 3':5'-cyclic monophosphoric acid in glial cells. The effects of the immobilized catecholamines are of longer duration than when the compounds are administered in solution. The present data indicate that the compounds are exerting their action when bound to the beads.
