Lectins assumed mechanism of action against SARS-CoV-2. A) ACE-2 recognition of by the viral S-protein and interference of plant lectin. B) Action of plant lectin on exposing of the virus epitope determinant site. The Virus N-glycan shield the virus epitope determinant and prevent the antibodies recognition. Upon lectin binding, conformational changes occur and lead to exposing the epitope site.
