Cell density remains constant as brain shrinks with age

New, ultra-high-field magnetic resonance images (MRI) of the brain by researchers at the University of Illinois at Chicago provide the most detailed images to date to show that while the brain shrinks with age, brain cell density remains constant. The images provide the first evidence that in normal aging, cell density is preserved throughout the brain, not just in specific regions, as previous studies on human brain tissue have shown.


Autoimmunity: New immunoregulation and biomarker


Clinicians at Ludwig-Maximilians-Universitaet (LMU) in Munich have elucidated a mechanism involved in determining the lifespan of antibody-producing cells, and identified a promising new biomarker for monitoring autoimmune diseases like multiple sclerosis and lupus erythematosus.
