#Glycan
the HIV envelope protein, the V3-glycan epitope. Many prior attempts to target the V3-glycan epitope of Env have worked under the assumption that antibodies must interact with a specific sugar, the Asn332 glycan, to neutralize HIV. As a result, immunogens were designed to preserve this glycan.

By deep characterisation of 186 N-glycan standards, we @thencfg.bsky.social have made the most comprehensive targeted LC-MS glycomic assay to date.
Non-reduced native glycan analysis is key.
We hope this enables anyone with QqQ and interest in #glycotime to measure specific N-glycan structures.

animal models showing that the Asn332 glycan is underrepresented in transmitted or founder viruses, and infection with Asn332-glycan-deficient viruses has been associated with the later development of Asn332-dependent bNAbs in humans. In addition, two human V3-glycan bNAbs, EPTC112 and 007, were

An interesting fact that some may not know is that viruses, including SARS-CoV-2, use sugar molecules on their surfaces to hide from the immune system, much like a protective coating (sugar coatings aren't only for candies). Now, researchers have developed a UNIVERSAL coronavirus

found to neutralize HIV without contacting the Asn332 glycan. This provided evidence that Asn332-glycan-independent bNAbs COULD develop in humans. To test their hypothesis, researchers designed WIN332 as an Asn332-glycan-deficient priming immunogen and evaluated it in nonhuman primates. Their data

Analysis of these responses showed that WIN332 elicited antibodies closely resembling potent human V3-glycan bNAbs. The data also found two distinct classes of antibodies: type-I antibodies that depend on the Asn332 glycan, AND a new type-II class of antibodies that remain glycan independent.

details how researchers engineered a protein that removes the N332-glycan completely to produce their candidate WIN332, an unprecedented approach to current vaccine efforts that have focused on preserving N332-glycan. The development of WIN332 potentially addresses one of the big challenges in HIV
May 14, 2026 at 4:04 PM
Researchers, however, deliberately removed the Asn332 glycan completely to create WIN332, thinking that early antibody precursors may not require it and that glycan dependence could develop later through somatic hypermutation. This line of thinking is supported by earlier studies in both humans and

Our new paper in print describes a new approach: release and analysis of N-glycans in less than 24 hours. A perfect approach for those that are glycan-curious as it does not require changing any of your proteomics buffers! 1/5

Enzyme extracts of our favourite mucin glycan degraders cleave different bonds that occur in mucins. 🍬

Expression of glycoside hydrolases also differs per species. ✂️
