How Do Cancer Cells Use Proteins to Avoid Detection by the Immune System?
Cancer cells can manipulate proteins to evade the immune system. One common strategy involves the overexpression of proteins like PD-L1, which bind to PD-1 receptors on T cells and inhibit their activity. This allows cancer cells to avoid being attacked by the immune system. Immunotherapies, such as checkpoint inhibitors, are designed to block these interactions and enhance the immune response against cancer cells.
