Discover how ETH Zurich researchers uncovered GRK2 enzyme aggregates as a novel Alzheimer's target, offering new hope for energy-restoring therapies.

Your brain consumes roughly 20% of your body's energy, meaning it relies on a massive network of blood vessels. To protect your central nervous system from harmful chemical swings and infections, the cells lining these blood vessels fit together like microscopic puzzle pieces sealed with airtight biological glue. This tight network is the Blood–Brain Barrier.

The recent study focuses on the hippocampus—the brain's primary center for memory and learning. Think of the hippocampus as a lush garden. For the first five decades of your life, this garden is tended by "resident immune cells.

There is a massive blind spot in the current landscape of neurodegenerative care, and it’s one that should keep every health-tech developer awake at night.
