Abstract:
Chronic respiratory diseases affect over 450 million people worldwide and result in 4 million deaths per year. The majority of lung diseases are treated with drugs delivered directly to the lungs. However, there is bidirectional crosstalk between the lung and other organs/tissues in health and disease. This crosstalk supports targeting of extrapulmonary sites in addition to the lung to improve the comorbidities associated with lung disease. However, new preclinical in vivo and in vitro assays that model the human pathophysiology are required. In this review, we showcase the latest knowledge of the bidirectional relationship between the respiratory system and organs affected by comorbidities such as obesity and atherosclerosis. We also discuss the impact of new cell culture systems, including complex 3D culture models that may be used as platforms to generate disease insights and for drug discovery. This review highlights work presented by Respiratory and Inflammation Special Interest Group researchers as part of the Australasian Society of Clinical and Experimental Pharmacologists and Toxicologists (ASCEPT) annual scientific meeting in 2023.

Common Respiratory Disorders
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...
