Results
We report 30 proteins with some relevance to disease, clinical subtype, or severity.
Strikingly, we observed widespread protein depletion in the disease CSF as compared to control.
We identified numerous markers of relapsing disease, including KLK6 (kallikrein 6, OR = 0.367, p < 0.05), which may be driven by active disease as defined by MRI enhancing lesions. Other oligodendrocyte-enriched proteins also appeared at reduced levels in relapsing disease, namely CNDP1 (carnosine dipeptidase 1), LINGO1 (leucine rich repeat and Immunoglobin-like domain-containing protein 1), MAG (myelin associated glycoprotein), and MOG (myelin oligodendrocyte glycoprotein).
Finally, we identified three proteins—CNDP1, APLP1 (amyloid beta precursor like protein 1), and OLFM1 (olfactomedin 1)—that were statistically different in relapsing vs. progressive disease raising the potential for use as an early biomarker to discriminate clinical subtype.
