Immunofluorescent analysis of TDP-43 in control, mutant TDP-43 and mutant TDP-43+HDAC6 inhibitor after 12 h treatment. Presented immunofluorescent images of control (C2) and mutant TDP-43 (P2). Scale bar: 25µm. B Profile intensity plot of control, mutant TDP-43 and mutant TDP-43+HDAC6 inhibitor. C Quantification of nucleo-cytoplasmic ratio (N/C) fluorescent intensity of TDP-43 in motor neurons, each dot represents one analyzed cell, unpaired Mann-Whitney-test.
