Um estudo de 2023 descobriu que a queda nos níveis da proteína menina no hipotálamo impulsiona múltiplos sinais de envelhecimento em camundongos. Restaurar a proteína ou suplementar com o aminoácido D-serina melhorou a memória e outros indicadores.

Pesquisadores da Universidade de Xiamen, na China, mostraram que os níveis de menina caem drasticamente em uma parte específica do hipotálamo conforme os camundongos envelhecem. Quando reduziram a menina em animais mais jovens, os camundongos desenvolveram inflamação cerebral, ossos mais frágeis, pele mais fina, pior equilíbrio, perda de memória e expectativa de vida mais curta.

UCSF study links iron-associated protein FTL1 to age-related memory decline in mice

Researchers at the University of California, San Francisco report that higher levels of the iron-associated protein FTL1 in the hippocampus of older mice are tied to weaker neural connections and worse performance on cognitive tests. In the experiments, reducing FTL1 in older mice was associated with increased neuronal connectivity and improved memory performance, findings published in Nature Aging.

Scientists call for multi-pronged strategies against Alzheimer's

A team of researchers led by Professor Yan-Jiang Wang has published a review arguing that Alzheimer's disease requires integrated treatments targeting multiple factors, not single causes. New drugs like lecanemab and donanemab offer modest benefits by slowing decline, but fall short of reversal. The paper, in Science China Life Sciences, emphasizes genetics, aging, and systemic health alongside amyloid-beta and tau proteins.

Scientists restore memory in Alzheimer's mice by blocking PTP1B

30 de abril de 2026 Reportado por IA

Researchers at Cold Spring Harbor Laboratory have found that blocking the protein PTP1B improves memory and boosts plaque clearance in mouse models of Alzheimer's disease. The discovery links the protein to brain immune function and metabolic risks like diabetes and obesity. The team aims to develop inhibitors for potential human treatments.

Researchers at Texas Children’s Hospital’s Duncan Neurological Research Institute and Baylor College of Medicine report an experimental gene-targeting approach designed to increase levels of the MeCP2 protein disrupted in Rett syndrome. In mouse experiments and neurons derived from patient cells, the strategy boosted MeCP2 and partially restored cellular structure, electrical activity and gene-expression patterns, according to findings published in Science Translational Medicine.

Strategies to Reduce Peripheral Inflammation and Alzheimer's Risk

06 de março de 2026 Reportado por IA

Building on genomic research linking Alzheimer's origins to inflammation in peripheral tissues like the gut, lungs, or skin, practical lifestyle measures can help curb chronic inflammation. These include vaccination, oral hygiene, diet, exercise, weight control, and stress management, offering benefits for overall health amid evolving science.
