## Mechanistic Overview
Hypothesis 1: MANF/CDNF Signaling as Primary Neuroprotective Effector starts from the claim that modulating MANF, CDNF within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "**Molecular Mechanism and Rationale** The mesencephalic astrocyte-derived neurotrophic factor (MANF) and cerebral dopamine neurotrophic factor (CDNF) represent a unique family of evolutionarily conserved proteins that function as endop
## Mechanistic Overview
The metabolic coupling between astrocytes and motor neurons represents a critical bioenergetic partnership that becomes compromised in neurodegeneration, particularly in diseases involving VCP mutations such as ALS and FTD. Under physiological conditions, astrocytes take up glucose via GLUT1 transporters and convert it to lactate through glycolysis, exporting it via MCT1 (SLC16A1) and MCT4 (SLC16A7) to provide energy substrates for neighboring motor neurons, which prefer
