What biological mechanisms explain the distinct KFLC-Index patterns across MOGAD, NMOSD, and MS?

OPEN

The study shows dramatically different KFLC-Index levels (MOGAD: 0.60, NMOSD: 8.85, MS: 49.90) but doesn't explain why these demyelinating diseases produce such distinct intrathecal immune responses. Understanding these mechanisms could reveal fundamental differences in disease pathophysiology and guide targeted therapies.
