Microglial Upregulation of Progranulin as a Marker of Motor Neuron Degeneration

Abstract excerpt

Frontotemporal lobar degeneration (FTLD) and amyotrophic lateral sclerosis (ALS) are overlapping neurodegenerative disorders. Mutations in the growth factor progranulin (PGRN) gene cause FTLD, sometimes in conjunction with ALS; such mutations are also observed in some ALS patients. Most PGRN mutations underlying FTLD are null mutations that result in reduced PGRN levels. We investigated PGRN expression in human...
