A study from the Monell Chemical Senses Center reports that, calorie for calorie, fructose and glucose engage different gut–brain pathways in mice. The researchers found glucose more strongly suppresses activity in hunger-related AgRP neurons, while fructose produces a weaker effect through a pathway involving the gut hormone PYY and signaling via the vagus nerve.

Researchers at Baylor College of Medicine report that tubulin—the building block of microtubules—can shift Tau and alpha-synuclein inside cellular condensates away from disease-linked aggregation and toward roles that support healthy neurons.

A study in mice has found that transplanting gut microbes from young animals into older ones can restore youthful levels of brain plasticity. The research points to potential new ways of treating conditions that are normally only reversible in childhood.
