Spending great days with the 🇫🇷 glyco community of GFG. Honored to receive and share the Verbert-Fournet Award 2026 with my chem alter ego (and also roommate 😄), Ahmed El Rhaz. Congrats to @rebekkawild.bsky.social for the GFG 2026 Award, and to everyone for the quality of discussions. #glycotime

New piece from our lab: alpha-Gal syndrome from a glycobiologist's point of view. How glycans in ticks' saliva immunize us, and how our immune system responds to similar glycans present in red meat. Glycoproteins/glycolipids discussed. @alphagal-info.bsky.social tinyurl.com/55762ewu #glycotime
Day 2 of #CGS2026 was packed with 21 presenters and an engaging poster session, showcasing the incredible breadth of research happening in #glycomics and #glycoscience. The evening banquet was also a great opportunity to connect and continue conversations. #glycotime
My student Lena Nuschy giving her flash presentation about anionic glycan arrays at #CGS2026, organised by @glyconet_nce, in Canmore, Alberta
Yesterday we kicked off #CGS2026! It's fantastic to see strong engagement from the #glycomics community with over 190 attendees gathered from across Canada and internationally. Looking forward to a great few days of science, discussion, and new ideas! #glycotime #glycoscience
A great paper, with multiple approaches to characterise ST8Sia IV. #glycotime Polysialylation of HEK N-glycans, O-glycans, and even plant polysialylation. It would have been nice to see a little mass spec, but I'm biased :) pubs.acs.org/doi/full/10....
Polysialic Acid Synthesis on the N- and O-Glycans of Salmonid Polysialyltransferase ST8Sia IV
Extension of N- and O-glycans with linear sialic acid polymers (polySias) was described on a limited number of mammalian glycoproteins, including the α2,8-polysialyltransferases ST8Sia II and ST8Sia IV. Previous in vitro analyses have shown that ST8Sia IV from the salmonid fish Coregonus maraena (Cma) had high polysialylation activity and broader donor substrate specificity compared to its human counterpart. In this study, we investigated whether the fish ST8Sia IV was able to polysialylate N- and O-glycans of glycoproteins with a focus on its autopolysialylation capacity. Using a combination of strategies, including plant-based glycoengineering, we found that the Cma ST8Sia IV is able to use both types of acceptors for the formation of long polySia chains with a degree of polymerization of >40 consisting of N-acetylneuraminic acid and N-glycolylneuraminic acid. Given the importance of polySias in multiple health and disease states, the Cma ST8Sia IV represents a useful biocatalyst with applications in the fields of biosafe therapeutics and glycobiology.

Wee thread 🧵⬇️ on our new #glycotime with @siglecdude.bsky.social John Klassen and @glycocode.bsky.social 🥳 where we show Siglecs as molecular precision tools, able to recognise sialylated glycans with surgical precision in their natural environment, not bad for a lectin! 😎 doi.org/10.1038/s420...

Silvia's simulations showed that while all epitopes expose Sia for binding, Siglec-6 recognises and binds only GM1 because of a key interaction with the membrane through W127 and K126, which orientates the V-set domain to bind the Sia through Arg122 and the terminal Gal to the C-C' loop 😎
