Protein engineering

Focusing immune responses by immunogen hyperglycosylation

We engineer immunogens in silico to add glycans onto the surfaces we don't want antibodies to see — masking immunodominant but variable regions so the response focuses on the conserved, protective epitopes we choose. Our HyperImmunISE (Hyperglycosylating Immunogen through In Silico Engineering) workflow places glycosylation sites that maximize surface coverage while minimizing steric overlap, iterating against structural evaluation before experimental validation.

HyperImmunISE immunogen engineering workflow: define target residues, identify native glycosylation sites, maximize glycan coverage, minimize overlapping sites, evaluate surface coverage in an iterative loop, then experimental validation — designing hyperglycosylated antigens that mask off-target surfaces and focus the antibody response on conserved epitopes.
The HyperImmunISE workflow: from a defined target epitope, glycosylation sites are placed to maximize coverage of off-target surfaces while minimizing overlap — iterated against surface-coverage evaluation before experimental validation.

Glycan masking — hiding the distractions

Adding N-linked glycans to immunodominant, non-conserved surfaces dampens off-target responses and redirects B cells toward the conserved epitopes that confer broad protection.

In silico design — HyperImmunISE

An algorithm selects glycosylation sites that maximize surface coverage while minimizing steric clashes, iterating with structural evaluation to produce immunogen candidates for experimental validation.
