Figure 4. Representative confocal immunofluorescence images from the right and left ventricular myocardium of the patient and a control heart. A - Normal immunoreactive signal for the non-desmosomal protein N-cadherin (control used to judge the quality of the sample); B - Severely depressed immunoreactive signal for plakoglobin; C - Reduced immunoreactive signal for desmoplakin; D - Normal immunoreactive signal for plakophilin-2. LV = left ventricle; RV = right ventricle.
