Immune surveillance

The following session will cover immune surveillance, focusing on the mechanisms by which the immune system detects and eliminates abnormal or cancerous cells and the key immune cell types involved in this process. We will discuss the concept of immunoediting, including the phases of elimination, equilibrium, and escape that characterize the dynamic between tumors and immunity. Strategies cancer cells use to evade immune destruction, such as down regulating antigen presentation and creating an immunosuppressive environment will be highlighted. Finally, we will examine the clinical implications of immune surveillance, including increased cancer risk in immunodeficient individuals, and the development of immunotherapies, like checkpoint inhibitors and CRT cell therapy. Immune surveillance is the process by which the immune system continually monitors the body for abnormal cells, particularly cancerous ones. This ongoing patrolling allows early detection and elimination of cells that become malignant. A network of immune cells, including antigen presenting cells, natural killer cells, cytotoxic T lymphocytes, bee cells, and macrophages, works together to recognize and remove threats. While many transformed cells are eliminated, some evade detection and may eventually lead to cancer. Multiple cell types contribute to immune surveillance. Antigen presenting cells, such as dendritic cells and macrophages are essential for sampling proteins, processing them, and presenting fragments on
