Distribution of SARS-CoV-2 in the OB. (a) Sagittal sections of the whole brain stained by SARS-CoV-2 in mock and 2 dpi. Planes A and B are shown as coronal sections in Fig. 2b,c. The asterisk indicates the frontal cortex. Scale bar, 1 cm. (b) Representative image of the coronal section of the OB. Right panels are high-magnification images of the GL in NAD(P)H quinone oxido-reductase 1 (NQO1)-positive (upper) and –negative (lower) regions. White dashed circles indicate glomeruli. Scale bars, 1 mm (left), 100 μm (right). (c) Left panel shows a representative image of the coronal section of the cerebral hemisphere. The white box indicates hippocampal formation (HPF). Right panel is a high-magnification image of the HPF; CA1, CA3, and DG. Scale bar, 1 mm.
