[2] Asthma is caused by multiple genes , some having protective effect, with each gene having its own tendency to be influenced by the environment although a ...
Bronchial thermoplasty[ 1] is a treatment for severe asthma approved by the FDA in 2010 involving the delivery of controlled, therapeutic radiofrequency energy to the airway wall, thus heating the tissue and reducing the amount of smooth muscle present in the airway wall. This reduces the capacity of the immune system to cause ...

2. -adrenergic agonist. Beta2-adrenergic agonists, also known as adrenergic β2 receptor agonists, are a class of drugs that act on the β 2 adrenergic receptor. Like other β adrenergic agonists, they cause smooth muscle relaxation. β 2 adrenergic agonists' effects on smooth muscle cause dilation of bronchial passages, vasodilation in muscle ...
