retinal cells

A cross-section of the retinal pigment epithelium in an ACE2-expressing mouse infected with SARS-CoV-2. Top image: Bright-field view with immunofluorescence showing SARS-CoV-2 N-protein (green) and complement component C3b (magenta). Bottom image: Immunofluorescence of C3b alone. Widespread C3b accumulation is visible, even though N-protein expression is limited to two small regions. Scale bars: 50 µm.
