  "account": "A new study employing subcellular proteomics across the spectrum of Alzheimer's disease-resilience reveals significant intracellular remodeling. Traditional proteomics have limited insight into protein localisation, a critical functional aspect of the proteome. In Alzheimer's disease, amyloid-beta and tau proteins display abnormal localisation, but their impact on the entire proteome has been challenging to assess.\n\nTo address this, researchers developed a comparative subcellular proteomics technique applied to dorsolateral prefrontal cortex tissue from 75 individuals representing the spectrum of Alzheimer's disease and resilience. This approach enabled the modeling of protein localisation patterns across disease progression. The analysis identified 217 localisation shifts associated with disease, with a notable enrichment in endolysosomal function, intracellular trafficking, and RNA processing. Among these, several tau proteoforms were resolved within insoluble aggregates.\n\nThe strongest localisation candidates showed only minor differences in abundance when considering whole tissue, indicating disease-related biological changes that remain undetectable through conventional proteomics methods. One of the most significant findings was the co-localisation of CSNK1A1 with pathological tau, providing new insights into the interaction between these proteins in Alzheimer's disease.\n\nAnother surprising discovery from this study was the identification of a previously uncharacterized neuronal localisation pattern for SCAI, a protein typically associated with cancer. This unexpected finding underscores the potential of subcellular proteomics to uncover novel biological insights within tissue samples.",
  "summary": "Proteome-wide analyses of human tissue have transformed our understanding of disease, but provide limited insight into protein localisation, a functionally informative dimension of the proteome. In Alzheimer's disease, amyloid-{beta} and tau exhibit aberrant localisation, yet whether spatial reorganisation extends proteome-wide has remained inaccessible to abundance-based proteomics. Here, we…",
