By suppressing a single gene, scientists triggered the transformation of astrocytes into neurons in the mouse substantia nigra, where the converts released dopamine and connected with the striatum.
Many Alzheimer’s trials had minimal dosing interruptions, but recruitment stopped for a time. Others trials fared worse, with some scrapped altogether. One administered study drug in an ambulance.
As the SARS-Cov-2 infection peak passes in some areas, scientists are resuming lab work and clinical studies, albeit with new safety protocols in place. Regions differ greatly in how fast they can reopen.
A postmortem study found that people who had more aggregation-prone, hyperphosphorylated, oligomeric forms of tau in their brains also had a more aggressive form of Alzheimer’s disease during life. Will we personalize tauopathy care like cancer care?
New research suggests the R47H variant protects neurons from neurodegeneration, raising questions about staging and direction of future TREM2-based therapy.
