Article Abstract

Lung diseases affect pulmonary and respiratory function and are caused by bacterial viral and fungal infection as well as environmental factors. Unfortunately, symptom overlap between various pulmonary diseases often prevents clear differentiation and uncertain diagnosis. Accordingly, identification of specific markers of inflammatory activity in early disease stage could potential unveil the intrinsic molecular mechanisms of the underlying pathology. Proteomic studies aimed at understanding the genetic/environmental contributions to the development and progression of lung diseases represent a promising approach for diagnosis and treatment. The fluid phase of sputum represents a rich protein source and is frequently used in these studies. This chapter addresses causes of lung disorders, sputum composition, collection and processing as well as the clinical significance and challenges associated with the presence of interfering factors. Basics of proteomics and mass spectrometry are also described, together with the analytical approaches to investigate the sputum proteome. Finally, we explore the application of sputum proteomics in severe lung disorders including COVID-19 infection, chronic obstructive pulmonary disease, asthma, cystic fibrosis, lung cancer and tuberculosis.
