Co‐pathologies and biological processes beyond amyloid‐beta and tau in people with Alzheimer's disease: Evidence from clinical cohort studies

Journal of Internal Medicine, Volume 299, Issue 6, Page 694-710, June 2026.
Abstract Alzheimer's disease (AD) is neuropathologically defined by amyloid‐beta (Aβ) plaques and tau neurofibrillary tangles. However, co‐pathologies and other pathobiological processes are involved in the pathogenesis of AD, contributing to neurodegeneration and clinical symptoms.

Dehnel's Phenomenon in Mammals

Mammal Review, Volume 56, Issue 2, June 2026.
Some small mammals, which remain active year‐round, undergo reversible reductions in body size, braincase height, and the mass of internal organs, including the brain, from summer to winter. It is called Dehnel's phenomenon. In this review, we summarise knowledge of the mechanisms, adaptive value, and genetic basis of the phenomenon, and show how new ...

Asymptomatic Versus Symptomatic Alzheimer's Disease Neuropathology: A Systematic Review of Differences Reported in Post‐Mortem Studies

Neuropathology and Applied Neurobiology, Volume 52, Issue 3, June 2026.
Graphical summary of post‐mortem brain tissue findings that differ between symptomatic and asymptomatic AD. Current evidence suggests reduced accumulation of Aβ and p‐tau oligomers, particularly at synapses, preserved neuronal and synaptic integrity and metabolic activity and a dynamic profile of glial and immune responses in ASYMAD.

Polycystin‐1 Controls Cell Cycle Kinetics, Cell Cycle Exit, and Differentiation of Neural Progenitor Cells

The FASEB Journal, Volume 40, Issue 9, 15 May 2026.
Earlier in neurogenesis, knockdown of polycystin‐1 (PC1) expression increases the cell cycle length of neural progenitor cells (NPCs) by extending the S‐phase and probably lengthening the G1‐phase. Subsequently, reduced PC1 expression causes delayed cell cycle exit and delayed neuronal differentiation of NPCs.

Copper Overload Affects α‐Synuclein Clearance Mechanisms in a Parkinson's Disease In Vitro Model

Advanced Biology, Volume 10, Issue 5, May 2026.
This study reveals that copper overload disrupts neuronal protein clearance, leading to the accumulation of α‐synuclein and its phosphorylated form (p‐S129). By blocking autophagy and impairing the ubiquitin–proteasome system, copper promotes toxic aggregation in dopaminergic cells.
