SEOUL, South Korea, July 26, 2023 /PRNewswire/ -- Our respiratory system is lined with a thin fluid layer called mucus on the inside. The mucus protects us from inhaling harmful and unwanted airborne agents from germs to pollutants; it achieves this feat due to its unique gel-like texture imparted by proteins called mucins. By extension, over- or under-secretion of mucins can lead to abnormal respiratory mucus—a pathological manifestation in many respiratory diseases like chronic bronchitis, cystic fibrosis, and asthma, among others. Although multiple clinically approved drugs are available that can combat abnormal respiratory mucus, many of them cause unwanted and potentially serious side effects. This calls for an alternative solution to provide relief to patients having respiratory diseases.
