flexiVent featured in recent Nature publication


Congratulations to Dr. Ravichandran’s1 team at the University of Virginia, who recently published in Nature!

Their publication found that during phagocytosis, macrophages release insulin-like growth factor 1 (IGF-1) and microvesicles. Once bound to its receptor, IGF-1 promotes uptake of these microvesicles by the epithelial cells, leading to a decreased inflammatory response. This was verified through classic airway hyperresponsiveness (AHR) markers including increased eosinophils in the BAL fluid and increased airway resistance after methacholine challenges.
In vivo AHR was assessed using the flexiVent to both deliver aerosol challenges to the subject’s lungs and follow the developing bronchoconstriction through automated data collection. The data generated can be further partitioned to describe the contribution from the central airways and tissues, which often offers additional insight into the mechanisms and disease.
