  1. The presence/absence of each protein’s expression within GCIs and NCIs in MSA brains, and within LBs in PD brains is displayed. The lists of proteins and their profiles described above are modified from [72, 95, 96].
  2. +, positive; +/−, partially or weakly positive; −, negative; ND, not described. *, described as +, or +/− when the positivity was recognized in either brainstem-type or cortical LBs; **, proteins other than iron-related proteins; ***, amino-terminal 17 kDa fragment of Apolipoprotein E
