Glycoengineering of the IgG glycan profile is important for the development of next-generation therapeutic antibodies with enhanced or silenced effector functions. TransGLYCIT translgycosylated antibodies with defined Fc glycoforms to generate agalactosylated, galactosylated or sialylated glycan profiles.
WebApr 3, 2013 · The anti-inflammatory role of α2,6-sialylated IgG was further confirmed using the recombinant form to mimic the protective effect mediated by IVIG . It is important to note that compared to Fc, Fab portion of human IgG is highly sialylated; 15–20% of human IgG has highly sialylated N-linked glycans on the Fab portion of human IgG . WebInteractions between the Fc segment of IgG and FcγRs on a variety of cells are likely to play an important role in the anti-HIV activity of Abs. Because the nature of the glycan structure on the Fc domain is a critical determinant of Fc–FcγR binding, proper Fc glycosylation may contribute to Ab-mediated protection.
