Brains of MSA and probable iLBD cases contain pathogenic alpha-synuclein. Immunohistochemical staining with an antibody against phosphorylated alpha-synuclein (81A) revealed glial cytoplasmic inclusions in cortical brain tissue sections from the MSA1 patient a and in cerebellar brain tissue sections from the MSA2 patient b. Staining of cortical brain tissue sections with the same antibody also showed granular deposits of phosphorylated alpha-synuclein in the cytoplasma and in neurites of cortical neurons from the iLBD1 c and iLBD2 cases d, e.
