21-in rescues desmosome structures during CVB3 infection.

<p>HL-1 cells were transfected and infected as indicated. “Sham” and “CVB3” are plain HL-1 cells infected with PBS or CVB3 at 10 MOI for 24 h, respectively. “CL-in-CVB3” and “21-in-CVB3” are HL-1 cells transfected with CL-in or 21-in and then infected with CVB3 at 10 MOI for 24 h. Desmosomes were analyzed by EM and indicated with black arrow. For each sample, 100 cells were analyzed and the numbers of desmosomes observed were indicated. Magnification: 37000×. Bar: 0.5 µm.
