Zusammenfassung der Projektergebnisse

The main conclusions from the present comprehensive study are: 1) TMEM16 proteins (anoctamins) are proinflammatory, prosecretory and proproliferative in airways, intestine, and other tissues. 2) Inhibitors of TMEM16 reduce inflammation, bronchoconstriction, and mucus secretion in airways and intestine while activators of TMEM16 show opposite effects. 3) Inhibitors of TMEM16A are beneficial in the treatment of inflammatory airway diseases such as asthma, COPD, CF, and COVID-19 in mouse and human. 4) We propose low dose systemic application of niclosamide or benzbromarone, or high topical aerosol application of either compound to reduce inflammation along with mucus hypersecretion, bronchospasm, and pulmonary arterial hypertension in asthma, COPD and CF. Niclosamide is proposed as a treatment in severe COVID-19 and other highly inflammatory airway diseases.
