简要总结
In recent years, obesity and its complications have severely threatened human health. Given the limited options for obesity treatment currently available, there is an urgent need to develop new drugs and therapeutic methods to alleviate patient suffering.
Mammalian adipose tissue is primarily divided into energy-storing white fat and energy-consuming brown fat. Physical activity, exposure to cold, and other factors induce the transformation of white fat into energy-consuming brown fat, a process known as adipose tissue browning. The occurrence of adipose tissue browning increases the body's energy expenditure and dissipates it in the form of heat, effectively mitigating the onset of obesity. Therefore, the regulatory mechanism of adipose tissue browning has become an important potential target for obesity treatment.
The main component of asthma medication is the β2 adrenergic receptor agonist, which can act on GPCR receptors on the surface of the tracheal smooth muscle through inhalation, causing bronchial dilation and thereby alleviating asthma symptoms. Preliminary experimental results have shown that pulmonary epithelial cells can secrete protein factors that regulate the browning process of adipose tissue, and the expression of these secretory factors is regulated by the cell surface GPCR receptor signaling pathway. Therefore, our goal is to validate the regulatory effect of the asthma medication salbutamol on adipose tissue browning through inhalation administration in humans, establishing a new function for asthma medication in obesity treatment.
