FIGURE 1.

Schematic diagram showing the role of mucins in susceptibility toward COVID‐19. Different glycosylation patterns on mucins may aid or prevent the entry of SARS‐CoV2 into the target cells. Different glycosylation patterns on mucins may (1) prevent the binding of the S protein to its receptors (ACE2 and NRP1) on the target cell by steric hindrance and (2) modulate entry of the SARS‐CoV2 into the target cells by regulating the expression of co‐receptors (for example, MUC1 regulates expression of NRP1). The diagram was created with Biorender and Autocad
