Abstract Cell-based immunotherapies have tremendous potential Rabbit polyclonal to AURKA interacting to treat many diseases, such NAMI-A as activating immunity in cancer or suppressing it in autoimmune diseases. Most cell-based cancer immunotherapies in the clinic provide adjuvant signals through genetic engineering to enhance T cell functions. However, genetically encoded signals have minimal control over dosing and persist for the life of a cell lineage. These properties make it difficult to balance increasing.
