The Irvine laboratory works at the interface of materials science and immunology. They use synthetic model systems to study immune cell biology and synthesize new materials for vaccines/immunotherapy, using a mechanistic understanding of the immune system to guide the design of these materials. They have pioneered the use of patterned surfaces as tools to dissect T-cell activation, using the ability to control the density, placement, and mobility of T-cell ligands, supported membranes, or entire cells on surfaces to dissect the functions of the immunological synapse in T-cell triggering. In a second focus, they study leukocyte chemotaxis/chemokinesis; they have discovered novel mechanisms for chemokine-mediated control of naïve lymphocyte migration, and shown that both T-cell and B cell migration in secondary lymphoid organs may be regulated by a complex interplay of chemokinesis and chemotaxis. Building on these fundamental findings, they have developed chemokine-releasing microparticles and hydrogels as tools to study immune cell migration and adjuvants to modulate cell migration in vaccines and immunotherapy. Finally, they have developed nanoparticles that can address key challenges in immunotherapy: (i) vaccine particles that co-deliver high doses of antigen in concert with immunostimulatory ligands, (ii) nanoparticles that deliver proteins or oligonucleotides to the cytosol of dendritic cells without cytotoxicity, and (iii) synthetic particles with surfaces structurally mimicking the envelope of pathogens.
