To differentiate NK cells, membrane receptors can be analyzed
The proteins that can be found on their membrane are CD16 and CD56
They act on tumor cells, virus-transformed cells, and cells infected with bacteria and other pathogens.
Recognition of target cells
Contact with target cells and the formation of an immunological synapse
Death of the target cell induced by NK cells
Cytokine secretion function
The ability to secrete various types of cytokines
Regulatory proteins, tumor necrosis factor alpha (TNF-α), gamma interferon (IFN-γ)
Granulocyte-macrophage colony-stimulating factor (GM-CSF)
Proliferation, differentiation, and activation of the immune response
Detecting cells that have undergone malignant transformation
