Age-Related Memory Loss Reversed In Mice

Reconstituting the amount of chondroitin 6-sulphate to perineuronal nets completely restored memory and brain plasticity in aging mice to a similar level as seen in younger animals, a new study reports. The findings could lead to new therapies to restore age-related memory loss in older humans.

The Brain Can Induce Diabetes Remission in Rodents, but How?

Researchers demonstrate how a single injection of fibroblast growth factor 1 (FGF1) can restore blood sugar levels to normal for extended periods in rodent models of type 2 diabetes. Studies show how FGF1 affects specific neurons and perineuronal nets to help restore blood sugar levels to normal, thus sending diabetes into remission.

Bad diets making for bad memories

Perineuronal nets (PNNs) and the neurons they enmesh can be damaged by poor diets. Excessive consumption of foods high in saturated fats and refined sugars cause inflammation and oxidative stress, resulting in cognitive decline and poor memory.
