Glial Therapeutics for Neurodegeneration
Overview
Glial therapeutics represent a promising frontier in neurodegenerative disease drug development for Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, targeting the non-neuronal cells of the brain (microglia, astrocytes, oligodendrocytes) that play critical roles in neurodegeneration. This analysis covers microglial modulators, TREM2 agonists/antagonists, complement inhibitors, astrocyte-targeted therapies, CSF1R inhibitors, and NLRP3 inhibitors.[@microglial2023]
Rationale
Glial cells—particularly microglia and astrocytes—are increasingly recognized as key drivers of neurodegeneration:
Microglia: The brain's resident immune cells; drive neuroinflammation via TREM2, complement, and cytokine signaling[@nlrp2024]
Astrocytes: Support neuronal metabolism; dysfunction leads to potassium buffering failure (AQP4) and neurotransmitter dysregulation
Oligodendrocytes: Myelin-producing cells; dysfunction contributes to axonal degeneration

Glial therapeutic investments have increased significantly from $500M in 2019 to over $2.1B in 2024, representing a 4x increase in venture funding and pharma partnerships.
Gap Analysis
Unmet Needs
Blood-brain barrier penetration - Many glial targets require CNS-penetrant compounds
Biomarker development - TREM2 and microglial biomarkers needed for patient selection
