Abstract：
:There is conflicting data in the literature as to whether subsensitivity of in-vivo beta 2-adrenoceptor (beta 2-AR) responses in patients with asthma is due to an endogenous defect of beta 2-AR or an effect of exogenous beta 2-agonist therapy. The purpose of the study was to compare in-vitro parameters of lymphocyte beta 2-AR function in eight age and sex matched normal [FEV1, 98 (2)% predicted] volunteers and asthmatic [FEV1, 60 (5)% predicted] subjects. The asthmatic group were washed out for 4 weeks by substituting inhaled beta 2-agonist therapy with ipratropium bromide, in order to exclude possible exogenous effects of beta 2-agonist exposure. Receptor binding affinity (Kd) and density (Bmax) were evaluated using (-)125I-iodocyanopindolol and maximal cAMP response (Emax) was assayed following stimulation with isoprenaline (10(-4) M). No significant differences were found between the normal and asthmatic group for Kd (pmol.l-1): 9.65 vs 10.2, Bmax (fmol/10(6) cells): 1.9 vs 1.6, or Emax (pmol/10(6) cells): 4.24 vs 4.85. Thus, parameters of beta 2-AR function are unaltered in asthmatic patients who have not been exposed to beta 2-agonists, suggesting that asthma is not associated with an endogenous defect of beta 2-AR.
