Natural Killer Cells are an incredible component of the immune system due to their versatility and wide range of functions. Besides their ability to directly kill infected or cancerous cells, NK cells also participate in regulating immune responses. They can produce various cytokines and chemokines that influence the behavior of other immune cells, orchestrating a coordinated defense against pathogens. NK cells are not confined to a specific tissue or organ. They circulate throughout the body, patrolling tissues and organs, ready to respond to any threat.

Furthermore, Natural Killer Cells exhibit adaptability, as they can adjust their response according to the specific context and signals received from the surrounding environment. In addition to their pivotal role in immune surveillance and cancer immunosurveillance, research has highlighted the potential of NK cells in immunotherapy. Scientists are exploring strategies to enhance the effectiveness of NK cell responses against tumors, such as adoptive cell transfer and engineering NK cells to express specific receptors.
