Endothelial glycocalyx is damaged in diabetic cardiomyopathy: angiopoietin 1 restores glycocalyx and improves diastolic function in mice (2022)
Journal Article
Qiu, Y., Buffonge, S., Ramnath, R., Jenner, S., Fawaz, S., Arkill, K. P., …Satchell, S. C. (2022). Endothelial glycocalyx is damaged in diabetic cardiomyopathy: angiopoietin 1 restores glycocalyx and improves diastolic function in mice. Diabetologia, 65(5), 879-894. https://doi.org/10.1007/s00125-022-05650-4

Aims/hypothesis

Diabetic cardiomyopathy (DCM) is a serious and under-recognised complication of diabetes. The first sign is diastolic dysfunction, which progresses to heart failure. The pathophysiology of DCM is incompletely understood but microci...

Hypertrophic cardiomyopathy (HCM) is characterised by increased left ventricular wall thickness that can lead to devastating conditions such as heart failure and sudden cardiac death. Despite extensive study, the mechanisms mediating many of the asso...

A Reinterpretation of Evidence for the Endothelial Glycocalyx Filtration Structure (2021)
Journal Article
Arkill, K. P. (2021). A Reinterpretation of Evidence for the Endothelial Glycocalyx Filtration Structure. Frontiers in Cell and Developmental Biology, 9, Article 734661. https://doi.org/10.3389/fcell.2021.734661

The endothelial glycocalyx is thought to be the primary macromolecular filter for fluid flux out of the vasculature. This filter maintains the higher protein concentration within the vessel lumen relative to the tissue. Whilst the arguments for the e...

Although macula densa (MD) cells are chief regulatory cells in the nephron with unique microanatomical features, they have been difficult to study in full detail due to their inaccessibility and limitations in earlier microscopy techniques. The prese... Read More about A new view of macula densa cell microanatomy.

Non‐invasive measurement of retinal permeability in a diabetic rat model (2020)
