Abstract:
BACKGROUND:beta2-Adrenergic agonists play a pivotal role in the management of bronchial asthma. Although the major effect of short-acting beta2-agonists on the airway is relaxation of smooth muscles, they may also have several effects on surrounding immunomodulatory cells. METHODS:We examined whether widely used short-acting beta2-agonists differ in their ability to modulate granulocyte functions, such as superoxide anion (O2-) production and degranulation. RESULTS:Procaterol (PC), a full agonist, significantly inhibited both O2- production by granulocytes (neutrophils and eosinophils) and their degranulation at the clinically relevant concentrations, whereas salbutamol and tulobuterol (partial agonists) showed smaller effects. PC inhibited N-formyl methionyl-leucyl-phenylalanine-induced O2- production and peroxidase release, but failed to inhibit responses induced by phorbol 12-myristate 13-acetate and/or opsonized zymosan. Exposure to 5 x 10(-8)M PC for 120 min resulted in approximately 50% inhibition of O2- production and degranulation of neutrophils. The effects of beta2-agonists were more obvious in neutrophils than in eosinophils. A selective beta2-receptor antagonist, ICI-118551, reversed the inhibitory effect of beta2-agonists (PC, salbutamol, tulobuterol B) on N-formyl methionyl-leucyl-phenylalanine-induced O2- production. CONCLUSIONS:These results suggest that beta2-agonists had an inhibitory effect on granulocyte functions, mainly mediated viareceptors and their efficacy. Our observations support that beta2-agonists with a rapid onset of action and high intrinsic efficacy (short-acting and full agonists) may be optimal for the rescue therapy against acute asthma attack and sedation of its airway inflammation in an early phase.
