WebN-glycans are classified into three types, based on the sugar structure attached to the common core sugar structure of three mannoses (Man) and two N-acetyl-glucosamines (GlucNAc) linked to the asparagine residue: (a) high mannose: only mannoses are attached to the core; (b) hybrid: the Manα1-6 arm is attached to only mannoses, and the Manα1 ... 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).
