In cell biology, a lymphokine-activated killer cell (also known as a LAK cell) is a white blood cell, consisting mostly of natural killer, natural killer T, and T cells that has been stimulated to kill tumor cells, but because of the function in which they activate, and the cells they can successfully target, they are classified as different than the classical natural killer and T lymphocyte ...
Natural killer (NK) cells are a type of lymphocyte cell involved in the innate immune system's response to viral infection and tumor transformation of host cells. [20] [7] Like T cells, NK cells have many qualities characteristic of the adaptive immune system, including the production of “memory” cells that persist following encounter with antigens and the ability to create a secondary ...
Natural killer cells, also known as NK cells, are a type of cytotoxic lymphocyte critical to the innate immune system.They are a kind of large granular lymphocytes [1] [2] (LGL), and belong to the rapidly expanding family of known innate lymphoid cells (ILC) and represent 5–20% of all circulating lymphocytes in humans.

KLRC2 has been shown to interact and form dimers with CD94. [5] [6] The CD94/NKG2C heterodimer can bind to HLA-E [7] [8] and this binding leads to NK cells activation.During infection with human cytomegalovirus, peptides derived from the virus are presented on HLA-E and natural killer cells that express the CD94/NKG2C receptor can specifically recognise the virus peptides.
In cancers, a Killer Activation Receptor (KAR), located on the surface of the NK cell, binds to certain molecules which only appear on cells that are undergoing stress situations. In humans, this KAR is called NKG2D and the molecules it recognizes MICA and MICB. This binding provides a signal which induces the NK cell to kill the target cell. [9]

Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
