BIOBRIEF
SORLA, a sorting related receptor already known to defend against amyloid, also protects neurons from tau in a Sanford Burnham Prebys mouse study, pointing to a drug target in supporting brain cells.
A brain protein called SORLA (sorting-related receptor with A-type repeats) protects neurons from the toxic tau tangles that drive Alzheimer's and related dementias, according to a study published July 17, 2026 in Science Advances. The work, led by Timothy Huang at Sanford Burnham Prebys, is the first to extend SORLA's known protective role from amyloid-beta, the other hallmark of Alzheimer's, to the tau side of the disease.
Tau normally stabilizes the scaffolding inside neurons. When it detaches and clumps, the tangles disrupt circuits and accelerate cognitive decline. In mice engineered to overproduce SORLA, tau accumulation fell, brain atrophy eased, and connections between neurons stayed healthier. Mice lacking SORLA showed the opposite: worse tau-driven damage.
The team also identified a candidate drug target in glia, the brain's supporting cells, which appear to control how much SORLA neurons make. Existing Alzheimer's drugs only modestly slow decline, so any new mechanistic angle matters. The result is still preclinical, and translating a mouse target into a human treatment typically takes a decade and often fails.
