Target note

Full name
Translocator protein (TSPO)
Nature
Outer mitochondrial membrane protein overexpressed by activated microglia and macrophages.
Normal expression
Low in healthy brain; high in kidneys, heart, lungs, adrenals.
Value
A marker of neuroinflammation and macrophage activation.
Approaches
[11C]PBR28, [18F]DPA-714, [11C]PK11195, [18F]GE-180, [18F]FEPPA.
Indications explored
Multiple sclerosis, neurodegenerative diseases, stroke, trauma; vascular and cardiac inflammation.
Points of caution
A genetic polymorphism (rs6971) changes the affinity of second-generation tracers and requires genotyping.
