Newly mapped #brain networks link far-flung regions
#Astrocyte networks in #mice link distant brain regions in ways nerve cell wiring does not.
This system, made of star-shaped cells called #astrocytes, is no relic, a new study reports. It’s operational, linking locales near and far in flexible, mysterious ways.
What’s more, astrocyte networks may also have roles in disorders such as #Alzheimer’s disease, traumatic brain injuries and stroke.

To capture this local heterogeneity, the authors developed a #multiphoton #FLIM approach with the Na⁺ indicator ING-2 and #astrocyte labeling, enabling quantitative Na⁺ measurements in individual #astrocytes and their processes. This is important because astrocytic Na⁺ is not just a bulk somatic variable. It varies locally across branches and subdomains, where K⁺ uptake and #glutamate-linked Na⁺ influx are regulated.

🧠🎨 New paper by Meyer et al: #astrocytic #sodium #homeostasis is not uniform. Using multiphoton #FLIM in #mouse #brain slices and #invivo, they show strong #cellular and #subcellular heterogeneity in astrocytic Na⁺ levels.
Processes contain more Na⁺ than somata, Na⁺ varies between #astrocyte branches, and distinct Na⁺/K⁺-ATPase subunit patterns help tune local K⁺ uptake and #glutamate-linked Na⁺ influx.

🧠 New paper by Cooper et al., who introduce a method to trace #astrocyte #gapjunction networks in vivo and show that astrocytes form selective, plastic networks linking specific #brain regions rather than one diffuse brain-wide syncytium. These networks can span long distances, differ from known #neuronal projections, and reorganize after sensory deprivation:

i've seen a few papers in the last 10 years demonstrating direct #astrocyte involvement in a variety of brain functions normally associated with #neurons... does this mean that the definition of the #connectome should be somehow augmented with astrocyte topologies, relative to the neuronal ones?

Alzheimer’s Drug Lecanemab Shields Brain from Free-Roaming Amyloid Fibrils
Amyloid beta protein forms small aggregates that disrupt brain function in Alzheimer’s disease.

A new study has revealed that astrocytes, a type of brain cell, can turn into neurons and restore memory in mice with Alzheimer’s disease. Astrocytes are star-shaped glial cells that support and protect neurons. The study found that activating a gene called Ascl1 in astrocytes can reprogram them into functional neurons and reverse cognitive decline. The study offers a potential new strategy for treating Alzheimer’s disease.

Imaging Study Implicates Reactive Astrocyte-Neuron Interaction in Alzheimer’s Cognitive Decline
PET imaging with 11C-acetate and 18F-FDG was used to visualize the reactive astrocyte-induced acetate hypermetabolism and associated neuronal glucose hypometabolism in brains with neuroinflammation and Alzheimer’s Disease.
