Comparing 2 hypotheses side-by-side
## Mechanistic Overview Hippocampal CA3-CA1 circuit rescue via neurogenesis and synaptic preservation starts from the claim that modulating BDNF within the disease context of Alzheimer's disease can redirect a disease-relevant process. The original description reads: "**Molecular Mechanism and Rationale** The CA3-CA1 hippocampal circuit represents a fundamental neural pathway essential for episodic memory formation and consolidation, making it a critical target for Alzheimer's disease (AD) thera
## 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. The original description reads: "## 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
