Spatial map of the lung reveals cellular mechanisms driving damage and fibrosis in severe COVID-19

A lung affected by deadly forms of COVID-19 not only loses essential cells for breathing but also undergoes profound changes in its internal organization and the way its cells communicate with each other. A study involving the Sant Pau Research Institute (IR Sant Pau), published in Nature Communications, has created a spatial map of this transformation and identified some of the molecular mechanisms that accompany the progression of lung damage and fibrosis.
