Smooth muscle in abnormal airways

Y Bossé - Current Opinion in Physiology, 2021 - Elsevier
The degree of airway responsiveness is generally measured by directly activating the airway
smooth muscle (ASM) with incremental doses of inhaled methacholine. In this context …

Small airways vs large airways in asthma: time for a new perspective

GM Donovan, PB Noble - Journal of Applied Physiology, 2021 - journals.physiology.org
Is asthma predominately a disease of the large or small airways? The question has vexed
these pages for at least 50 years (1–4) and although a consensus appears to be emerging …

Force adaptation through the intravenous route in naïve mice

M Boucher, C Henry, Y Bossé - Experimental Lung Research, 2023 - Taylor & Francis
Aim of the study: Force adaptation is a process whereby the contractile capacity of the
airway smooth muscle increases during a sustained contraction (aka tone). Tone also …

Airway smooth muscle tone curbs hyperresponsiveness in experimental asthma
