Identifying latent classes of longitudinal change in picture naming in a population-based sample
Although cognitive changes may not become apparent until after age 65, many factors associated with late-life decline are already well-established in midlife. In particular, deficits in picture naming have been associated with early and accelerated cognitive change. A measure of picture vocabulary, requiring participants to name drawings of objects, was collected in 4 waves (each separated by 2 years) of the Understanding America Study, a nationally representative internet panel (mean follow-up...

Amyloid β-dependent neuronal silencing through synaptic decoupling
Amyloid β (Aβ)-dependent circuit dysfunction in Alzheimer's disease (AD) is determined by a puzzling mix of hyperactive and inactive ("silent") brain neurons. Recent studies identified excessive glutamate accumulation as a key Aβ-dependent determinant of hyperactivity. The cellular mechanisms underlying neuronal silence depend on both Aβ and tau protein pathologies, with an unknown role of Aβ. Here, by using single-cell-initiated rabies virus (RV) tracing in mouse models of β-amyloidosis, we...
PTMs as molecular encoders: reprogramming chaperones into epichaperomes for network control in disease
Recent discoveries reveal that post-translational modifications (PTMs) do more than regulate protein activity - they encode conformational states that transform chaperones into epichaperomes: multimeric scaffolds that rewire protein-protein interaction networks. This emerging paradigm expands the framework of chaperone biology in disease and provides a structural basis for systems-level dysfunction in disorders such as cancer and Alzheimer's disease. This review explores how PTMs within...
