From: Complement activation in the Parkinson's disease substantia nigra: an immunocytochemical study
Percentages of iC3b-positive melanized neurons in different groups of substantia nigra specimens. The percentage of iC3b+ melanized neurons was significantly increased in PD vs. both aged normal and AD specimens, and in young normal vs. aged normal specimens. Data are expressed as means ± SEM. (ap < 0.05 vs. PD; bp < 0.05 vs. young normal specimens; abbreviations: AD, Alzheimer's disease; AN, aged normal; DLB, dementia with Lewy bodies; PD, Parkinson's disease; YN, young normal)
