Asthma, accompanied by lung inflammation, bronchoconstriction, and airway hyper-responsiveness, is a significant public health burden.  Currently, asthma treatments such as anticholinergics target the hypersensitive nerves connecting the brain to parasympathetic neurons in the smooth muscle of the airway.  Therefore, insights into the neural mechanisms underlying the pathogenesis of asthma are highly desirable.  Now, a study from researchers at Johns Hopkins identifies skin itch receptors in … Continue reading Researchers identify neuronal colonies responsible for ‘itchiness’ in the throats of mice.
