Deciphering proteins in Alzheimer's disease: A new Mendelian randomization method integrated with AlphaFold3 for 3D structure prediction

7 months ago
Hidden confounding biases hinder identifying causal protein biomarkers for Alzheimer's disease in non-randomized studies. While Mendelian randomization (MR) can mitigate these biases using protein quantitative trait loci (pQTLs) as instrumental variables, some pQTLs violate core assumptions, leading to biased conclusions. To address this, we propose MR-SPI, a novel MR method that selects valid pQTL instruments using Leo Tolstoy's Anna Karenina principle and performs robust post-selection...

Monoclonal therapy with lecanemab in the treatment of mild Alzheimer's disease: A systematic review and meta-analysis

7 months ago
Alzheimer's disease, a progressive neurodegenerative pathology, is characterized by the accumulation of Amyloid-β plaques in the brain. Lecanemab (BAN2401), a humanized IgG1 monoclonal antibody, binds with high affinity to Amyloid-β protofibrils. It is the first monoclonal antibody for Alzheimer's disease to receive full FDA approval. This systematic review, conducted meticulously, examines the current use and safety of Lecanemab in treating Alzheimer's disease. We screened literature from...

Multifaceted roles of DLG3/SAP102 in neurophysiology, neurological disorders and tumorigenesis

7 months ago
DLG3, also known as Synapse-associated protein 102 (SAP102), is essential for the organization and plasticity of excitatory synapses within the central nervous system (CNS). It plays a critical role in clustering and moving key components necessary for learning and memory processes. Mutations in the DLG3 gene, which result in truncated SAP102 proteins, have been associated with a range of neurological disorders, including X-linked intellectual disability (XLID), autism spectrum disorders (ASD),...
