- psu.edu reports: Researchers have identified a microscopic skeleton within neurons that acts as a "gatekeeper," controlling the absorption of substances by brain cells.
- psu.edu reports: This protective structure, known as the membrane-associated periodic skeleton (MPS), was found by Penn State scientists to regulate nearly every major form of endocytosis, or cellular intake.
- scitechdaily.com reports: When this internal gatekeeper weakens, neurons rapidly take in harmful proteins associated with Alzheimer's disease, as detailed by SciTechDaily.
- Stabilizing this newly understood "gatekeeper" could offer a novel strategy for preventing brain cell damage.
- The Economic Times notes that maintaining the integrity of this cellular skeleton may also be crucial for slowing neurodegeneration.
Brain Cell 'Gatekeeper' Fights Alzheimer's

Scientists have uncovered a microscopic "gatekeeper" skeleton within brain cells, called the MPS, which critically controls what substances neurons absorb. This discovery is vital because a weakened MPS allows harmful proteins linked to Alzheimer's disease to enter, suggesting its stabilization could prevent neurodegeneration.
