WebFeb 16, 2014 · The carbohydrate antigens that have been found to be tumor-associated include the mucin related Tn, Sialyl Tn, and Thomsen–Friedenreich antigens, the blood group Lewis related LewisY, Sialyl ... WebThe GL7 antigen has an epitope containing non-sulfated α2-6-sialyl-LacNAc recognized by the GL7 antibody. The GL7 antigen is expressed by pre-B and immature B cells, activated T and B cells, and about 20% of TCR-bright thymocytes. It is upregulated on mouse splenocytes following activation. It may play a role in regulation or adhesion.
WebApr 6, 2024 · The heavily shortened glycans induce a collapse of the peptide backbone and enable accessibility of the latter to immune cells, rendering it a tumor-associated antigen. Synthetic vaccines based on MUC1 tandem repeat motifs, comprising tumor-associated 2,3-sialyl-T antigen, conjugated to the immunostimulating tetanus toxoid, are reported herein. WebMar 13, 2008 · The Tn antigen (GalNAcα-Ser/Thr) is a biosynthetic intermediate in the formation of normal mucin-type O-glycans and is typically extended by the action of the enzyme core 1 β3 galactosyltransferase (core 1 β3Gal-T, T-synthase; ref. 11).Thus, Tn antigen expression results from lack of T-synthase activity.
WebBackground: The Sialyl-Thomsen-nouveau antigen (STn) is abundantly produced on many types of human epithelial cancers including epithelial ovarian cancer (EOC). We previously developed an EOC-specific lectin sandwich immunoassay (CA125MGL) using a human macrophage galactose-binding lectin coated on fluorescent europium nanoparticles … WebOct 7, 2009 · The T antigen is a tumor-associated structure whose sialylated form (the sialyl-T antigen) involves the altered expression of sialyltransferases and has been related with worse prognosis. Since little or no information is available on this subject, we investigated the regulation of the sialyltransferases, able to sialylate the T antigen, in …
