Figure Lengend Snippet: TBA immunofluorescence patterns of autoantibodies against astrocytes, neurons, or oligodendrocyte in double negative atypical IDD patients. (A) An immunofluorescence pattern of antibodies from patients with double negative atypical IDD binding to astrocytes at rat cerebral cortex (green), similar to commercial AQP4‐IgG (red). (B) An immunofluorescence pattern of antibodies from patients with double negative atypical IDD binding to astrocytes at rat cerebral cortex (green), similar to commercial GFAP‐IgG (red). (C) An immunofluorescence pattern of antibodies from patients with double negative atypical IDD binding to neurons at rat cerebral cortex (green), similar to commercial NeuN‐IgG (red). (D) An immunofluorescence pattern of antibodies from patients with double negative atypical IDD binding to oligodendrocytes at rat cerebellum (green), similar to commercial MOG‐IgG (red). (E) Seronegative immunofluorescence pattern. Nuclei were counterstained with 4′,6‐diamidino‐2‐phenylindole (DAPI) (blue). Scale bars: 100 μm. AQP4, aquaporin‐4; GFAP, glial fibrillary acidic protein; MOG, myelin oligodendrocyte glycoprotein; NeuN, neuronal nucleus.
Article Snippet: Serum GFAP of double negative atypical IDD patients was quantified using commercial Human GFAP DuoSet ELISA (R&D Systems Minneapolis, MN, USA) by an independent investigator who was blinded to the result of TBA.
Techniques: Immunofluorescence, Binding Assay
