The American Journal of Pathology Special edition opens with an overview of nanomechanics; the connections between the luminal surface endothelial glycocalyx and the intra-endothelial cortex, largely composed of actin molecules, is emphasised. The sequelae of endothelial glycocalyx injury include enhanced vascular permeability, tissue oedema, augmented leukocyte adhesion, platelet aggregation, and

Precapillary sphincters maintain perfusion in the cerebral cortex.
A beautifully illustrated report on the cerebral microcirculation of mice provides many answers to the role of precapillary sphincters in cerebral perfusion autoregulation. Grubb, S., Cai, C., Hald, B.O. et al. Precapillary sphincters maintain perfusion in the cerebral cortex. Nat Commun 11, 395 (2020). In previous blogs we considered the
