After shutting down a Phase 3 program last March, Biogen now says the futility analysis it did was incorrect, and that a new analysis of a larger dataset in fact supports filing for FDA marketing approval next year.
The resource boasts 56 stem cell lines derived from tau mutation carriers, patients with sporadic disease, healthy controls, and engineered isogenic lines, including some that have their mutation corrected by CRISPR.
The transcriptional repressor quiets neural activity and lengthens lifespan in worms. It is abundant in the brains of cognitively healthy centenarians.
Using chemical cross-linkers to map contacts among amino acids, structural biologists predict that soluble tau is, in fact, a compact globule containing β-sheets poised to snap into a pathological formation.
The protein helps internalize neuronal interleukin receptors. It also promotes microglial phagocytosis. Does its absence worsen neuroinflammation and Aβ burden?
Researchers induced cortical organoids to grow their own vasculature and even form a blood-“brain” barrier, making the little blobs more useful for studying disease.
