Antigen-presenting Cells
Antigen-presenting cells (APCs) are an essential part of the immune system. APCs are specialized cells that identify and process foreign substances, known as antigens, and present them to other immune cells, thus activating the immune response. This process helps the body to recognize and destroy pathogens, such as bacteria and viruses. APCs play a key role in the development of immunity and in the regulation of autoimmunity, as well as in the efficacy of vaccines and other medical treatments. They are also studied in cancer research, as their components are involved in cancer immunotherapy.
