Mannose-Binding Lectins as Potent Antivirals against SARS-CoV-2 [PDF]

Viruses, 2023
The SARS-CoV-2 entry into host cells is mainly mediated by the interactions between the viral spike protein (S) and the ACE-2 cell receptor, which are highly glycosylated.

Bioinformatic Selection of Mannose-Specific Lectins from Allium genus as SARS-CoV-2 Inhibitors Analysing Protein–Protein Interaction [PDF]

Life
Mannose-specific lectins are carbohydrate-binding proteins known for their antiviral potential. This study uses a bioinformatic approach to investigate the possibility of lectins from Allium sativum (garlic) and Allium ursinum (wild garlic) as inhibitors

Antibodies disrupt bacterial adhesion by ligand mimicry and allosteric interference [PDF]

Nature Communications
A critical step in infections is the attachment of microorganisms to host cells using lectins that bind glycans, making lectins promising antimicrobial targets. Upon binding mannosylated glycans, FimH, an adhesin in E.

Man-Specific Lectins from Plants, Fungi, Algae and Cyanobacteria, as Potential Blockers for SARS-CoV, MERS-CoV and SARS-CoV-2 (COVID-19) Coronaviruses: Biomedical Perspectives

Cells, 2021
Betacoronaviruses, responsible for the “Severe Acute Respiratory Syndrome” (SARS) and the “Middle East Respiratory Syndrome” (MERS), use the spikes protruding from the virion envelope to attach and subsequently infect the host cells.

Heterogeneity in glycan composition on the surface of HIV-1 envelope determines virus sensitivity to lectins. [PDF]

PLoS ONE, 2018
Lectins that target N-glycans on the surface of HIV-1 envelope (Env) glycoprotein have the potential for use as antiviral agents. Although progress has been made in deciphering the molecular details of lectin and Env glycan interaction, further studies ...

Viral Evasion of Innate Immune Defense: The Case of Resistance of Pandemic H1N1 Influenza A Virus to Human Mannose-Binding Proteins

Frontiers in Microbiology, 2021
Mannose-binding lectins effectively inhibit most seasonal strains of influenza A virus and contribute to the innate host defense vs. these viruses. In contrast, pandemic IAV strains are largely resistant to these lectins, likely contributing to increased
