- Artificial antigen presenting cells (aAPCs) are engineered platforms for T-cell activation. aAPCs are used as a new technology and approach to cancer immunotherapy. Immunotherapy aims to utilize the body's own defense mechanism—the immune system—to recognize mutated cancer cells and to kill them the way the immune system would recognize and kill a virus or other micro-organisms causing infectious diseases. Antigen presenting cells are the sentinels of the immune system and patrol the body for pathogens . When they encounter foreign pathogens, the antigen presenting cells activate the T cells—“the soldiers of the immune system”— by delivering stimulatory signals that alert there is foreign material in the body with specific cell surface molecules (epitopes). aAPCs are synthetic versions of these sentinel cells and are made by attaching the specific T-cell stimulating signals to various macro and micro biocompatible surfaces like micron-sized beads. This can potentially reduce the cost while allowing control over generating large numbers of functional pathogen-specific T cells for therapy. Activated and stimulated T cells can be studied in this biomimetic contex and used for adoptive transfer as an immunotherapy. (en)
