ACADL (Acyl-CoA Dehydrogenase Long Chain, mitochondrial flavoenzyme), ARG1 (Arginase 1), CD80, ELAVL4 (ELAV Like RNA Binding Protein 4), LYNX1 (Ly6/Neurotoxin 1), NOX4 (NADPH Oxidase 4), PPARGC1A (PPARG Coactivator 1 Alpha), TNF (Tumor Necrosis Factor) were absent from consensus PD-microglia and ABCA6 (ATP Binding Cassette Subfamily A Member 6) was not expressed in non-consensus PD-microglia. Here, TNF is linked to Parkinson disease.
