"Surprise Find in COVID-19 Brain Capillaries
— Could this contribute to COVID brain fog?"

I understand megakaryocytes make platelets, but why are cells usually found in bone marrow being found in cortical capillaries? Do they relate to RANTES in some way? Would they relate to leronlimab's role in platelet activation?

Thanks!
