Natural Killer Cells: The Tumor Killers

The video tutorial explains the role of natural killer (NK) cells in the immune system, highlighting their development, maturation, and functional diversity. NK cells are part of the innate immune system but share features with adaptive immunity. They develop from common lymphoid progenitor cells and mature through various stages. NK cells have diverse roles, including cytotoxic responses and cytokine production. Their activation depends on receptor signaling, balancing activating and inhibitory signals. NK cells can also develop memory and are involved in various diseases, including cancer and autoimmune disorders.
