Brain’s Energy Boost Mechanism Uncovered, Offers Hope for Late-Life Cognitive Health

Mutations in the presenilin gene, PSEN1, causes early onset of Alzheimer’s disease in humans and in fruit flies modified to have this gene. A new study led by researchers at Penn State revels that disrupting heparan sulfate–modified proteins in fruit flies suppressed neuronal death and corrected other cell deficits common in early stages of Alzheimer’s and other neurodegenerative diseases. Pictured here are full fruit fly brains, stained with a marker that indicates cell death—brighter colors indicate higher presence of cell death. Top: A fly with deficits in the presenilin gene—a model for Alzheimer’s disease—with high levels of cell death. Bottom: A fly rescued by disrupting heparan sulfate–modified proteins.

Inhibition of an ESI1 target promotes oligodendrocyte myelin production in mice, as shown as a dense curtain of green strands. This small molecule shows early promise as a potential treatment for MS, and to manage aging-related nerve sheath deterioration, according to study led by experts at Cincinnati Children's.

Lifelong RNA Molecules Hold the Key to Long-lived Brain Cells

Scientists at Washington University School of Medicine in St. Louis have shown that treating mice with an antibody that blocks the interaction between APOE proteins (white) sprinkled within Alzheimer’s disease plaques and the LILRB4 receptor on microglia cells (purple) activates them to clean up damaging plaques (blue) in the brain.
