GSTM1 and synucleinopathy: BAR-Serine 129-phosphorylated (Pser129) α-synuclein identifies enriched protein HBB localized to LP in synucleinopathy samples when BAR-SYN1 (total α-synuclein) in brain tissues of synucleinopathies and non-synucleinopathies have similar protein abundance patterns [5], which further confirms the interaction between α-synuclein and neuronal Hb and suggests a potential influence of Hb in α-synuclein pathology.
