Active surface flows accelerate the coarsening of lipid membrane domains

This study shows active surface flows accelerate lipid membrane domain coarsening from t1/3 to t2/3 growth rates.

Antibody binding reports spatial heterogeneities in cell membrane organization

This study quantifies spatial heterogeneities in membrane crowding on live cells using antibody binding, revealing sharp gradients near crowded regions and supporting raft-like domain exclusion of large proteins.

Molecular machines stimulate intercellular calcium waves and cause muscle contraction

This study shows light-activated molecular machines can remotely stimulate intercellular calcium waves, controlling muscle contraction in vitro and animal behavior in vivo.

Alterations in platelet proteome signature and impaired platelet integrin αIIbβ3 activation in patients with COVID-19

This study identifies altered platelet proteome and impaired integrin αIIbβ3 activation in COVID-19 patients, linked to increased platelet-neutrophil aggregates and thromboinflammation.

The SARS-CoV-2 Spike protein disrupts human cardiac pericytes function through CD147-receptor-mediated signalling: a potential non-infective mechanism of COVID-19 microvascular disease

This paper shows that SARS-CoV-2 Spike protein causes cardiac pericyte dysfunction through CD147-mediated signaling, without infecting the cells.
