Cytokine-induced killer cells (CIK) cells are a group of immune effector cells featuring a mixed T- and natural killer (NK) cell-like phenotype.They are generated by ex vivo incubation of human peripheral blood mononuclear cells (PBMC) or cord blood mononuclear cells with interferon-gamma (), anti-CD3 antibody, recombinant human interleukin (IL)-1 and recombinant human interleukin (IL)-2.
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 ...
It refers to cytokine storm syndromes (CSS) [4] and occurs when large numbers of white blood cells are activated and release inflammatory cytokines, which in turn activate yet more white blood cells. CRS is also an adverse effect of some monoclonal antibody medications, as well as adoptive T-cell therapies .
Natural killer T (NKT) cells are a heterogeneous group of T cells that share properties of both T cells and natural killer cells. Many of these cells recognize the non-polymorphic CD1d molecule, an antigen-presenting molecule that binds self and foreign lipids and glycolipids. They constitute only approximately 1% of all peripheral blood T ...
CCL2 is a small cytokine that belongs to the CC chemokine family. CCL2 tightly regulates cellular mechanics [ 5 ] and thereby recruits monocytes , memory T cells , and dendritic cells to the sites of inflammation produced by either tissue injury or infection .
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.

Short-term use of dexamethasone, a synthetic corticosteroid, has been demonstrated to reduce the severity of inflammation and lung damage induced by a cytokine storm by inhibiting the severe cytokine storm or the hyperinflammatory phase in patients with COVID-19. [34] Clinical trials continue to identify causes of cytokine storms in COVID-19 cases.
Cytokine-induced effector cytokine production [ edit ] IL-33 has a role in so called cytokine-induced effector cytokine production, which means that a production of effector cytokines by differentiated T helper lymphocytes is cytokine dependent and can happen without antigen stimulation by T-cell receptor of these cells.
