N-cadherin antagonism is bronchoprotective in severe asthma models.

Severe asthma induces substantial mortality and chronic disability due to intractable airway obstruction, which may become resistant to currently available therapies including corticosteroids and β-adrenergic agonist bronchodilators. A key effector of these changes is exaggerated airway smooth muscle (ASM) cell contraction to spasmogens. No drugs in clinical use effectively prevent ASM hyperresponsiveness in asthma across all severities.

Precision Cut Lung Slices: Emerging Tools for Preclinical and Translational Lung Research. An Official American Thoracic Society Workshop Report.

The urgent need for effective treatments for acute and chronic lung diseases underscores the significance of developing innovative preclinical human research tools. The 2023 ATS Workshop on Precision Cut Lung Slices (PCLS) brought together 35 experts to discuss and address the role of human tissue-derived PCLS as a unique tool for target and drug discovery and validation in pulmonary medicine. With increasing interest and usage, along with advancements in methods and technology, there is a growing need for consensus on PCLS methodology and readouts.

Editorial for special issue-human precision cut lung slices: an Ex vivo platform for therapeutic target discovery and drug testing in lung disease.

Publications utilizing precision cut lung slices (PCLS) steadily increased from the 1970's, with a significant increase in 2010, to tripling by 2023. PCLS have been used to study a vast array of pulmonary diseases and exposures to pathogens and toxicants to understand pathogenesis of disease but also to examine basic cellular mechanisms that underly lung biology. This Special Issue will highlight new, exciting, and novel research using PCLS, while acknowledging the substantial fund of knowledge that has been gained using this platform.
