Abstract:
Stimulation of the innate immune system has been implicated in ALS and particularly in distinct monogenic forms of ALS. To address whether this is of diagnostic value, we performed a proof-of concept study using qPCR to assess the Interferon score in blood samples of genetic ALS.
Abstract:
56.5% of genetic ALS patients showed significant IFN activation, highest in C9orf72HRE patients (77.3%). About half of FUS-ALS (52.2%), but none of SOD1-ALS patients demonstrated pathological IFN scores. The IFN score significantly correlated with the ALSFRS-R slope and inversely with the time to severe event as a survival surrogate in this genetic ALS cohort. IFN + patients were more likely to be male, showed more rapid disease progression and higher neurofilament levels.
Abstract:
The IFN score might have the potential as a stratification and readout tool for biomarker-guided individualized therapy in ALS.
