SIGLEC1 and infection: Recently, it was demonstrated that attachment to such receptors as CLRs, DC-SIGN, L-SIGN, and sialic-acid-binding immunoglobulin-like lectin 1 (SIGLEC1) enhances ACE2-mediated infection and modulates the neutralizing activity of distinct types of spike-specific antibodies (Rahimi, 2020; Amraei et al., 2021; Lempp et al., 2021).
