Equipe da Universidade de Indiana foca na enzima IDOL para tratar o Alzheimer

Pesquisadores da Faculdade de Medicina da Universidade de Indiana identificaram a enzima IDOL como um possível novo alvo para o tratamento da doença de Alzheimer. Estudos laboratoriais mostraram que a remoção da enzima de neurônios reduziu as placas amiloides e melhorou a comunicação entre as células cerebrais.

As descobertas, publicadas na revista Alzheimer's & Dementia, são provenientes de experimentos que utilizaram modelos animais da doença. A deleção do gene IDOL em neurônios diminuiu os níveis de placas e reduziu a apolipoproteína E, uma proteína associada a um maior risco de Alzheimer. Os efeitos foram mais fortes nos neurônios do que na microglia, as células de defesa do cérebro, contrariando as expectativas iniciais.

Researchers in Spain and Switzerland report that an experimental molecule called OLE helped restore protective behavior in the brain’s immune cells in animal models of Alzheimer’s disease, reducing amyloid-related pathology and improving performance on memory and movement tests.

Scientists at the University of Southern California have found experimental compounds that may reduce harmful brain inflammation associated with Alzheimer’s disease. The work focuses on the enzyme cPLA2 and people who carry the high-risk APOE4 gene.

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 have identified a previously unknown mechanism called karyoptosis that appears to drive the death of brain cells in Alzheimer's disease and frontotemporal dementia. The discovery, based on analysis of human brain tissue, points to a potential new target for treatments aimed at slowing neuron loss.

Researchers at UCLA have identified senescent immune cells, dubbed 'zombie' cells, that accumulate in aging livers and contribute to fatty liver disease. By eliminating these cells in mice, the team reversed liver damage and reduced body weight, even on an unhealthy diet. The findings, published in Nature Aging, suggest similar mechanisms may drive human liver conditions.
