Additional uses of nanotechnology for immunotherapy include immune depots placed in or near tumors for in situ vaccination and artificial antigen presenting cells. These and other approaches will advance and be refined as our understanding of cancer immunotherapy deepens.
What is immunotherapy for cancer?
Immunotherapy is a promising new front in cancer treatment encompassing a number of approaches, including checkpoint inhibition and cellular therapies. Although results for some patients have been spectacular, only a minority of patients being treated for just a subset of cancers experience durable responses to these therapies. Expanding the benefits of immunotherapy requires a greater understanding of tumor-host immune system interactions. New technologies for molecular and functional analysis of single cells are being used to interrogate tumor and immune cells and elucidate molecular indicators and functional immune responses to therapy. To this end, nano-enabled devices and materials are being leveraged to sort, image, and characterize T cells in the Alliance’s NanoSystems Biology Cancer Center.
