Cracking the Glycan Shield

A dense coat of sugar molecules is the reason HIV evades antibodies better than almost any other virus. This computational program uses an AI-driven pipeline to map where six antibodies can and cannot get through it, and to model how the virus mutates its way out from under the ones that do.

Virion Portrait

A mature HIV particle, cut in half and drawn to scale

Shows how few Env spikes sit on a virion and how far apart they are, alongside the real 5FYJ spike with a full sugar coat and an antibody for scale.

Coverage Explorer

Which of 525 real viruses does an antibody set reach?

Switch antibodies on and off and see how many viruses the set still neutralizes, with a check against the project's standing rule for choosing combinations.

Full-Density Glycan Shield

Complete Man9 glycans built onto every site of the 5FYJ trimer

A crystal structure shows only the first few sugars of each glycan. This 3D viewer builds the full shield so you can see how much of each antibody footprint it hides. It is a snapshot ensemble of a dense case, not a measurement of the real shield.

The Sampling Blind Spot

Why sequencing depth hides most independent escape events

Watch a virus population evolve resistance under antibody pressure, then see most of that resistance disappear once realistic sequencing depth is applied. The page uses a simplified illustrative model and gives the real-scale reference numbers beside it.

Origin Network

One participant's escape lineages, drawn out

Takes one participant from the 10-1074 monotherapy cohort through the source paper's own ancestor-matching code and draws each viral haplotype and each independent origin of escape, next to a simulated replicate.

About This Project

This is independent computational work, separate from my postdoctoral research. The report and companions are self-contained pages: each states its data sources, methods, and caveats, and cites the primary literature it draws on.

The reports were developed with AI-assisted tooling. The analyses are computational and exploratory; they are not experimental results and should not be read as clinical guidance.
