could be SARS-CoV-2 infection receptors as well as well-know ACE2.<br \/>\nHarvard Medical School, July 30, 2020<br \/>\n<a

(Dec. 22, 2020) in addition to the above paper, let me introduce two kinds of interesting data for your reference.<br \/>\n<a href=\"https:\/\/www.mdpi.com\/2079-7737\/10\/1\/1\">https:\/\/www.mdpi.com\/2079-7737\/10\/1\/1<\/a><\/p>\n<p>Although ACE2 is a really important virus receptor, the expression level of ACE in lung is very low, however, CD209 and CD209L are more broadly expressed in human tissues rather than the ACE2.<br \/>\nA result of infection experiments using SAR-CoV-2 pseudotyped lentivirus and HEK293 cells overly expressing CD209L, CD209, and ACE2 is also shown below.<br \/>\nTaking these things into consideration, it would be clear that CD209 and CD209L could mediate SARS-CoV-2 entry as infection receptors even for tissues lacking ACE2 expression.<br \/>\nThe CRDs of C-type Lectins (DC-SIGN, L-SIGN) recognize strongly high mannose type glycans.<\/p>\n<p><a
