New in @natureportfolio.nature.com on microglial regulation in Alzheimer’s disease. The study shows that microglia with low PU.1 expression and surface CD28 reduce amyloid pathology and inflammation. It highlights immune co-stimulatory pathways as potential targets in AD. Very interesting!

Great work 👏 mapping how brain endothelial cells communicate with astrocyte endfeet at the blood–brain barrier in @natureportfolio.nature.com The study identifies ligand–receptor pairs conserved in humans and altered in MS and Alzheimer’s. Makes me also wonder how many could be druggable targets.

Interesting new work @natureportfolio.nature.com showing that a small molecule identified through in silico transcriptome matching (thiorphan) enhances corticospinal regeneration after spinal cord injury. Combined with neural stem cell grafts, it improved forelimb recovery and axonal growth.

Let’s stop treating "leaving academia" as negative. Scientists train for academia, industry, or what suits them. Industry isn’t an alternative; it’s a choice. In fields like engineering, most PhDs go to industry, and no one calls it "leaving academia." We should train scientists for diverse paths.
