1: Presence of soluble SARS-CoV-2 host cell entry associated molecules
in amniotic fluid (AF) and breast milk (BM) at 2- and 6-weeks
postpartum. (A) Soluble molecules (ACE2, CD26, CD147 and NRP-1)
were measured in AF and BM using ELISAs. (B) The presence of
these soluble molecules was confirmed with Western Blotting and isoforms
were identified. (C) The presence of these soluble molecules in
AF and BM which the baby ingests and in the case of amniotic fluid also
aspirates may confer resistance to SARS-CoV-2 infection and/or severe
COVID-19. (The images in (C) were created with BioRender).
