SNCA and neuroblastoma: We probed for the presence of both the D5 and 10H reactive toxic α-synuclein aggregates in different mammalian cell lines expressing endogenous levels of α-synuclein including non-differentiated and differentiated human neuroblastoma cells (SH-SY5Y), Chinese hamster ovary (CHO) cells and human embryonic kidney (HEK) cells.
