Fig. 7From: Isolation and characterization of antibody fragments selective for human FTD brain derived TDP-43 variantsTherapeutic potential of anti-TDP scFvs. SH-SY5Y neuroblastoma cell line was treated with TDP-IP derived from human FTD and control brain tissue. The cells were further treated with a commercial anti-TDP antibody (ab190963, Abcam, 1 µg/mL) or anti TDP scFvs (FTD-TDP1, FTD-TDP2, FTD-TDP4 and FTD-TDP5) for 12 h. The cell damage and toxicity were tested by measuring lactate dehydrogenase (LDH). Neither the commercial TDP antibody or FTD-TDP4 significantly blocked toxicity of the FTD brain derived TDP IP at the concentration studied, while FTD-TDP1, FTD-TDP2, FTD-TDP3 and FTD-TDP5 all significantly inhibited the TDP induced toxicity.
