[Articles] The presynaptic protein bassoon is a biofluid biomarker of synaptic pathology in multiple sclerosis

In conclusion, the presynaptic protein BSN can be quantified in plasma and CSF to assess synaptic pathologies. BSN elevation was already detectable at the earliest disease stages and persisted in progressive MS, underscoring continuous neurodegeneration in MS. Measuring synaptic proteins may complement established biomarkers of neuronal injury to enhance our understanding of neurodegeneration in MS.
