Enhancing diagnosis of mild cognitive impairment through brain-heart-gut metabolic networks in whole-body PET imaging

3 weeks 6 days ago
Mild cognitive impairment (MCI) is the prodromal stage of dementia involving complex interactions between the brain and peripheral organs. Emerging evidence indicates that heart dysfunction and gut microbiota dysbiosis contribute to MCI pathogenesis. Here, we present a framework integrating brain-heart-gut interactions using whole-body positron emission tomography (PET) to enhance brain-only diagnostic performance. Our brain-only model achieves diagnostic performance comparable to that of...

Hallucinogenic Therapy in Alzheimer's Disease targeting Mitochondria-Associated Membranes

3 weeks 6 days ago
Mitochondrial dysfunction is increasingly recognized as a central driver of Alzheimer's disease (AD), contributing to neuroinflammation, synaptic failure, and energy collapse.Emerging preclinical evidence suggests that classic hallucinogens, such as psilocybin, lysergic acid diethylamide (LSD), N,N-dimethyltryptamine (DMT), mescaline, may restore mitochondrial integrity by activating Serotonin 2A (5-HT2A) and sigma-1(Sig-1R) receptors. In experimental models, these pathways are associated with...

Structural defects in amyloid-β fibrils drive secondary nucleation

3 weeks 6 days ago
Formation of new amyloid fibrils and oligomers from monomeric protein on the surfaces of existing fibrils is an important driver of many disorders such as Alzheimer's and Parkinson's diseases. The structural basis of this secondary nucleation process, however, is poorly understood. Here, we ask whether secondary nucleation sites are found predominantly at rare growth defects: irregularities in the fibril core structure incorporated during their original assembly. We first demonstrate using the...
