Comparing 2 hypotheses side-by-side
The debate supports carrying forward BDNF-mediated hippocampal synaptic rescue as a modifier of CA3-CA1 vulnerability only if a proximal endpoint changes before the late outcome. The decisive validation path is: deliver BDNF-pathway activation in hippocampal circuit models and test synaptic function before tau-mediated degeneration.
## Mechanistic Overview Hippocampal CA3-CA1 synaptic rescue via DHHC2-mediated PSD95 palmitoylation stabilization starts from the claim that modulating BDNF within the disease context of Alzheimer's disease can redirect a disease-relevant process.
