Aging macaques bridge the translational gap in perivascular space biology

William A. Liguore, Daniel L. Schwartz, Juan A. Piantino…·Alison R. Weiss

This study shows that aging rhesus macaques exhibit age-dependent perivascular space burden, mirroring human patterns, and validates MRI-detected structures as perivascular spaces.

Astrocyte extracellular matrix modulates neuronal dendritic development

Joel G. Hashimoto, Nicholas Margolies, Xiaolu Zhang…·Marina Guizzetti

The paper shows that ethanol inhibits astrocyte translation of Chpf2 and Chsy1, reducing CS-GAGs and increasing dendritic arborization in hippocampal neurons.
