## Mechanistic Overview
Beta-Hydroxybutyrate Receptor (HCAR2) Signaling Links Ketone Deficiency to Neuroinflammation starts from the claim that modulating HCAR2 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "**Molecular Mechanism and Rationale** The hydroxycarboxylic acid receptor 2 (HCAR2/GPR109A) represents a critical mechanistic bridge between metabolic dysfunction and neuroinflammation in neurodegenerative diseases. H
## Mechanistic Overview
Integrated Biomarker Panel for Therapeutic Window Identification starts from the claim that modulating CHI3L1 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "**Molecular Mechanism and Rationale** The integrated biomarker panel leverages the temporal dynamics of neurodegeneration to identify a critical therapeutic window through the convergence of three distinct molecular pathways. CHI3L1 (Chitinase-
