Mechanistic description
Aβ initially perturbs tau localization, but persistence depends on BIN1-regulated membrane and endocytic trafficking that prevents tau re-entry into the axon and stabilizes dendritic retention. This is a useful genetic-modifier hypothesis, but currently the least supported as a primary mechanism.
Mechanism / pathway
- BIN1,MAPT
- neurodegeneration
Evidence for (6)
BIN1 is a strong AD risk locus with links to tau biology and trafficking, supporting modifier-level relevance.
Dyadic Plasticity in Cardiomyocytes.
BIN1 regulates dynamic t-tubule membrane.
BIN1 is reduced and Cav1.2 trafficking is impaired in human failing cardiomyocytes.
Bend it like BIN1: how a membrane-curving adaptor protein shapes cardiac physiology.
Multilayered regulation of cardiac ion channels.
Evidence against (2)
The BIN1-tau relationship is complex and not straightforward, with sparse evidence that BIN1 controls post-Aβ persistence of missorting specifically.
Isoform- and cell-type-specific BIN1 biology makes simple causal interpretations in iPSC neurons uncertain.
