Brain Cells That Drive Anxiety in Mice Reveal Targets
What the new mouse study shows In a recent line of experiments with mice, researchers mapped specific brain cells that either amplify or suppress anxiety-like behaviors. By observing how these neurons activate during stressful situations, and how their activity shifts when anxiety is reduced, scientists are painting a more nuanced picture of the brain’s emotional…

Newly Identified Microglia Subtype Offers Protection Against Alzheimer’s Disease
Groundbreaking discovery: a protective microglia subtype In the ongoing effort to understand Alzheimer’s disease, researchers are turning the spotlight onto the brain’s immune sentinels: microglia. A newly identified subtype of these cells appears to play a protective role in the brain, potentially slowing the progression of Alzheimer’s disease. The finding, emerging from collaborations led by…

Medicine Nobel Winners Map Immune System’s Security Guards
What the Nobel Prize Recognizes The Nobel Prize in Physiology or Medicine has been awarded to a US-Japanese trio for breakthroughs in understanding how the immune system remains balanced. The laureates—Mary Brunkow and Fred Ramsdell from the United States and Shimon Sakaguchi of Japan—identified the immune system’s “security guards,” known as regulatory T-cells. This discovery…
