Overview of Gene Research
Dbh, also known as Dopamine β-Hydroxylase, is a copper-dependent mono-oxygenase that converts dopamine to norepinephrine, thus regulating the endogenous dopamine content in neurons [3,4]. This function is crucial for maintaining normal neurotransmitter balance and is involved in neural signaling pathways related to the nervous system's function [3,4]. Genetic models, such as KO/CKO mouse models, can be valuable tools for studying Dbh's functions.
In mice, repeated exposure to inhaled allergen activates a population of Dbh+ neurons in the nucleus of the solitary tract (nTS) of the brainstem in a mast cell -, interleukin-4 (IL-4)-and vagal nerve-dependent manner [1,2]. Ablation or chemogenetic inactivation of Dbh+ nTS neurons blunts allergen-induced airway hyperreactivity, a hallmark of asthma, while chemogenetic activation promotes it [1,2]. These findings suggest that Dbh+ nTS neurons play a key role in the allergen-induced airway hyperreactivity circuit [1,2].
In conclusion, Dbh is essential for regulating dopamine content in neurons. Studies using mouse models have revealed its significant role in allergen-induced airway hyperreactivity, a major aspect of asthma. These findings provide insights into potential neural modulation strategies for controlling this condition [1,2].
