This month on JHLT: The Podcast, the JHLT Digital Media Editors review two studies from the February issue of The Journal of Heart and Lung Transplantation—and bring in a couple of experts to help them make sense of some new technology.


First, the editors explore a pre-clinical study entitled “The dynamic cellular landscape of grafts with acute rejection after heart transplantation,” which comes from Kong and colleagues at Zhejiang University in Hangzhou, China.


Single cell technologies are emerging as non-biased techniques to discover novel biological pathways in a variety of pre-clinical models and in human tissue both in health and disease. To help the editors—and you!—understand single cell approaches and this study, JHLT editors Ben Kopecky, MD, PhD and Kory Lavine, MD, PhD, from the Washington University St. Louis, appear in the episode to explore the methodology and what the study tells us.


Second, the editors welcome author Sam Rayner, MD from the University of Washington in Seattle, USA, to discuss the paper by Hirsch and colleagues, “Circulating markers of inflammation and angiogenesis and clinical outcomes across subtypes of pulmonary arterial hypertension.”


When considering differences in pathophysiology of the subtypes of PAH, changes in biomarkers in angiogenesis and inflammation may provide useful insights and potential therapeutic targets. The authors of this study prospectively looked at 33 biomarkers of angiogenesis and inflammation in a cohort of patients across various PAH etiologies, and made correlations to clinical outcomes.
