Synthesis and Application of 3,3-Difluoro Sialic Acid as a Sialyltransferase and Neuraminidase Inhibitor
Abstract. Sialic acid (Neu5Ac) is a monosaccharide terminating glycoconjugates, serving as ligands for lectins in health and disease. Tools to target sialy

@tommorelloofficial.bsky.social We are celebrating your former band mate and Nobel winner Carolyn Bertozzi’s 60th birthday in October. Over 300 people will be in attendance at Stanford. I am a former student of her’s, and a happy birthday message from you would be amazing to include.

Sharing our latest work on B cell Siglecs in regulating antibody production. Unlike our previous work (PMID: 35294874), where we found that CD22 (Siglec-2) positively impacts the germinal center (GC), our new work uncovers a regulatory role for Siglec-G in the GC: www.biorxiv.org/content/10.6...

When glycan recognition is linked to immune response, you need fine tuning! 😎 Here ⬇️ we show how human Siglecs act as molecular precision tools, recognising the glycan and also the biological environment (or context) these glycans are found in. A 1/5 #glycotime🧵 ⬇️ doi.org/10.1101/2025...
