Kechuanting Acupoint Sticking Therapy Alleviates Type 2 Airway Inflammation in Mice with Allergic Asthma by Modulating the Number of ILC2s

ILC2s and total ILC2s in the lungs and exacerbated type 2 airway inflammation. Conversely, intranasal BIBN-4096 decreased pulmonary ILC2s and mitigated type 2 airway inflammation. KAST reduces airway inflammation in allergic asthma, which is closely associated with downregulation of the CGRP/RAMP1 pathway and subsequent suppression of pulmonary ILC2s, as supported by pharmacologic inhibition.
