WebFeb 1, 2024 · High mannose oligosaccharides are characteristic and essential for immune evasion of many viruses and cancer cells. They are potential targets for viral inhibition and cancer diagnosis/therapy. Particularly, high mannose-binding reagents may be a unique asset for fighting the ongoing and mutating SARS-CoV-2 virus. WebGlycans have an important role in immunity and self-recognition during common immune events and, ultimately, can impact the therapeutic efficacy of biopharmaceuticals (Gagneux & Varki, 1999; van Kooyk & Rabinovich, 2008). Therefore, controlling glycosylation in antibody biotherapeutics is of critical importance.
