Covalent modification of cell surfaces with TLR agonists improves & directs immune stimulation

We present a primary example of a cell surface modified with a synergistic combination of agonists to tune immune stimulation. A model cell line, Lewis Lung Carcinoma, was covalently modified with CpG-oligonucleotides and lipoteichoic acid, both Toll-like receptor (TLR) agonists. The immune-stimulat...

description We present a primary example of a cell surface modified with a synergistic combination of agonists to tune immune stimulation. A model cell line, Lewis Lung Carcinoma, was covalently modified with CpG-oligonucleotides and lipoteichoic acid, both Toll-like receptor (TLR) agonists. The immune-stimulating constructs provided greater stimulation of NF-κB in a model cell line and bone marrow-derived dendritic cells than the components unconjugated in solution.
