An iPSC-cardiac myocyte (heart muscle cell) surrounded by cardiac myocyte-derived small extracellular vesicles (tiny dots; AKA cardiosomes) and two cardiac myocyte-derived large extracellular vesicles (thankfully just called that; I love descriptive names). #CellBiology

The authors of the "zombosome" paper should have read our blebbisome paper. We showed that blebbisomes do not just come from cancer cells, they are also made by fibroblasts and can be isolated from wild type mice. It is a general cellular phenomenon. #CellBiology

Wow! Someone is already trying to rename blebbisomes! That took less than a year!

Zombosomes are anucleated cell couriers that spread α-synuclein pathology
Astrocytes not only play a central role in orchestrating the brain’s microenvironment but also are tightly connected to neurodegenerative processes. H…

Check out this editorial in Circulation Research by Dr. Marie-Louise Bang about our paper on alpha-actinin-4 in the cardiac Z-disc. It both summarizes our findings really well (image gives a taste of it; there is more) and lays out future directions.

Did you know that human cardiomyopathy drugs targeting beta myosin II can be used in zebrafish embryos to study heart development? Beta myosin II is only in the ventricle (v) allowing tuning up or down of ventricular contractility. #CellBiology
