Figure 1. 2-DE results. A representative two-dimensional electrophoresis (2-DE) gel images of cerebrospinal fluid proteins of neuromyelitis optica (NMO; A) and control (B). Numbers indicate proteins that were expressed differentially in the two groups. Protein spots 2, 6, 8, 11, and 12 were upregulated, whereas the other spots were downregulated in the NMO group (A) compared to the control group (B).
