The basal forebrain cholinergic system comprises several interconnected nuclei:
NBM neurons project widely to:
Medial septum cholinergic neurons project to:
Muscarinic receptors (GPCR):
Nicotinic receptors (ligand-gated):
The cholinergic anti-inflammatory pathway modulates neuroinflammation:
This pathway is relevant to AD where neuroinflammation contributes to pathology.
| Marker | Change in AD | Clinical Impact |
|---|---|---|
| ChAT activity | -40 to -70% | Reduced ACh synthesis |
| VAChT | -50% | Impaired vesicular filling |
| Muscarinic M1 | -30% | Signal transduction deficits |
| Nicotinic α4β2 | -40% | Receptor loss |
| Acetylcholine | -25 to -50% | Synaptic transmission failure |
