For immune cell differentiation, some reports show that CXCL9 lead to Th1 polarization through CXCR3. [17] In vivo model by Zohar et al. showed that CXCL9, drove increased transcription of T-bet and RORγ, leading to the polarization of Foxp3 − type 1 regulatory (Tr1) cells or T helper 17 (Th17) from naive T cells via STAT1, STAT4, and STAT5 phosphorylation.
The contribution of antibody-dependent cell-mediated cytotoxicity to tumor cell killing can be measured with a specific test that uses NK-92, an immortal line of NK-like cells licensed to NantKwest, Inc.: the response of NK-92 cells that have been transfected with a high-affinity Fc receptor are compared to that of the "wild type" NK-92 which ...
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 ...
The term "NK T cells" was first used in mice to define a subset of T cells that expressed the natural killer (NK) cell-associated marker NK1.1 (CD161). It is now generally accepted that the term "NKT cells" refers to CD1d-restricted T cells , present in mice and humans, some of which coexpress a heavily biased, semi-invariant T-cell receptor ...
Induced-self antigen is a marker of abnormal self, which can be recognized upon infected (in particular, virus-infected) and transformed cells. Therefore, the recognition of "induced self" is an important strategy for surveillance of infection or tumor transformation - it results in elimination of the affected cells by activated NK cells or other immunological mechanisms. [1]
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 ...

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.
