Description

Alvarez-González and co-authors look for proteins in airway muscle that may drive the twitchiness of airways in asthma. Airway hyperresponsiveness is a hallmark of the disease, but its molecular roots are still unclear. Working in guinea pigs with an induced allergic asthma model, the team measured airway response to histamine and analyzed tracheal tissue proteins with mass spectrometry. One known suspect protein was not found; instead, a peptide from a glycogen-targeting regulatory subunit, RG1, turned up.

Follow-up staining showed RG1 and a partner kinase, ROCK2, were both raised in the airway muscle of the asthma model, and their levels tracked the degree of hyperresponsiveness. The two proteins' levels also correlated with each other. The authors suggest RG1 may help drive the overreaction of asthmatic airways. As an animal study, the work points to a candidate mechanism rather than proving one in patients.
