Abstract
Long-term display of exogenous proteins on the cell surface may have important research and therapeutic implications. We report a novel method for the cell-surface display of proteins that involves generation of a chimeric protein with core streptavidin, biotinylation of cells, and "decoration" with the protein. A chimeric protein with the extracellular portions of FasL (SA-FasL) was efficiently displayed on the cell surface within 2 hr without detectable cellular toxicity. Biotin and SA-FasL persisted on the cell surface for weeks in vitro and in vivo. Immunomodulation with SA-FasL-decorated splenocytes effectively blocked alloreactive responses in naive and presensitized rodents and prevented the rejection of allogeneic pancreatic islets. This approach may serve as an alternative to gene transfer-based expression with broad research and therapeutic applicationsKeywords
