Figure 3

EV capsid protein VP1/TLR4 double staining of serial sections of myocardial tissue obtained from patients with DCM and controls. (a) Immunostainings of EV capsid protein VP1 (arrow, blue coloring) and TLR4 (arrow head, brown coloring) were positive in cardiac myocytes in biopsy samples obtained from DCM patients. VP1/TLR4 double staining showed colocalization of VP1 and TLR4 proteins in cardiac myocytes. (b) Immunostainings of VP1 and TLR4 in myocardial tissue obtained from control subjects. Neither VP1 nor TLR4 immunostaining was present in any specimens. Magnification: × 250.
