Consistent with our previous single-cell studies showing expression of relevant entry receptors ACE2 and TMPRSS2, in approximately 6.6% of conjunctival epithelial cells ex vivo (Collin et al., 2021b), SARS-CoV-2 infection of this ALI conjunctival epithelial model indicated broad but relatively inefficient infection of the various cell types by SARS-COV-2. The gene discussed is ACE2; the disease is infection.
