Figure 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).
