A quantitative neuropathological assessment of translocator protein expression in multiple sclerosis

Abstract

Radioligands targeting the 18 kDa translocator protein (TSPO) are increasingly used to visualise inflammation in the brain. Nutma et al. report that TSPO expression in multiple sclerosis lesions originates mainly from astrocytes and microglia, but is not restricted to cells with a specific pro-inflammatory phenotype.
