Astrocyte Subtypes Drive Synapse Formation and Memory

Astrocytes are not a uniform support crew. A breakthrough study in Nature reveals that CD51-positive astrocyte subtypes specialize in building synapses via glypican 6, tuning hippocampal memory circuits, and repairing damaged connections after a stroke.

Macrophages Settle in the Brain After Sepsis, Driving Memory Loss

Surviving sepsis often leaves patients with lasting memory deficits. Researchers discovered that peripheral macrophages infiltrate the hippocampus during acute infection, establish lifelong residency, and signal microglia to devour protective myelin.
