Extended Data Fig. 7: The spike protein of SARS-CoV-2 cannot induce inflammation and damage in mouse lungs.
From: TLR2 senses the SARS-CoV-2 envelope protein to produce inflammatory cytokines
a, CD45 immuno-staining and TUNEL staining of lung samples obtained from mice 24 h after being intratracheally instilled with the spike (S) protein from SARS-CoV-2. Data are representative of two independent experiments. Scale bar, 100 μm (black) or 25 μm (red).
