Researchers may have found out why some children thought to have asthma do not respond to treatment. They think it is due to the activation of a protein, transient receptor potential vanilloid 1 (TRPV1), that increases mucus production, stimulates the cough reflex and narrows the airways, which can suggest asthma even if no allergen is present. The protein is thought to be activated by respiratory syncytial virus (RSV).
