What is the role of the immune system in cancer cell interactions?
The immune system is both a barrier to and a facilitator of cancer progression. Immune cells, including T cells, macrophages, and natural killer (NK) cells, can recognize and destroy cancer cells. However, cancer cells can evade immune detection through various mechanisms, such as downregulating antigen presentation and secreting immunosuppressive molecules. The interplay between cancer cells and immune cells is a crucial area of research for developing immunotherapies.
