Because pTDP43 is present in RVs [12], [30], [31] and GVD bodies [35], we therefore performed double immunofluorescence staining using anti-pTDP43 antibody together with antibodies for CHMP2B, caspase 3, CDK5, CK1δ, JNK, LRRK2, annexin 2 and flotillin-1 in s-IBM cases. Here, CASP3 is linked to inclusion body myositis.
