Why does the use of bronchodilators of the $\beta$ 2 -class decrease in effect over time?

The use of β2-adrenergic receptor agonists (bronchodilators) can lead to a decrease in the number of lung adrenergic receptors over time due to downregulation, which is a cellular response to prolonged exposure to agonists. This results in decreased effectiveness of the drugs.
