IgG monoclonal proteins from patients with axonal peripheral neuropathies bind to different epitopes of the 68 kDa neurofilament protein
Abstract
We describe three patients with a sensorimotor axonal polyneuropathy and an IgG M-protein that binds to a 68 kDa axonal protein identified as the low molecular weight neurofilament protein (NF-L). The immunological studies revealed that the M-proteins have different target epitopes: one is phosphorylated and the other two are nonphosphorylated. One of the nonphosphorylated epitopes is common to other intermediate filaments, such as desmin and vimentin.
