Our previous results revealed that Igs in lesions and single chain variable fragment Abs (scFv-Abs) generated from clonal B cells in the cerebrospinal fluid (CSF) from patients with multiple sclerosis (MS) bind to axons in MS brains. To study the axonal Ags involved in MS, we identified the glycolytic enzymes, triosephosphate isomerase (TPI) and GAPDH, using Igs from the CSF and scFv-Abs generated from clonal B cells in the CSF and in lesions from MS patients. Elevated levels of CSF-Abs to TPI were observed in patients with MS (46%), clinically isolated syndrome (CIS) suggestive of MS (40%), other inflammatory neurological diseases (OIND; 29%), and other noninflammatory neurological diseases (ONIND; 31%). Levels of GAPDH-reactive Abs were elevated in MS patients (60%), in patients with CIS (10%), OIND (14%), and ONIND (8%). The coexistence of both autoantibodies was detected in 10 MS patients (29%), and 1 CIS patient (3%), but not in patients with OIND/ONIND. Two scFv-Abs generated from the CSF and from lesions of a MS brain showed immunoreactivity to TPI and GAPDH, respectively. The findings suggest that TPI and GAPDH may be candidate Ags for an autoimmune response to neurons and axons in MS.

D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D009103 Multiple Sclerosis An autoimmune disorder mainly affecting young adults and characterized by destruction of myelin in the central nervous system. Pathologic findings include multiple sharply demarcated areas of demyelination throughout the white matter of the central nervous system. Clinical manifestations include visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia, and bladder dysfunction. The usual pattern is one of recurrent attacks followed by partial recovery (see MULTIPLE SCLEROSIS, RELAPSING-REMITTING), but acute fulminating and chronic progressive forms (see MULTIPLE SCLEROSIS, CHRONIC PROGRESSIVE) also occur.
