  2. Natural killer cell - Wikipedia

    en.wikipedia.org/wiki/Natural_killer_cell

    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. [3]

  3. KLRC2 - Wikipedia

    en.wikipedia.org/wiki/KLRC2

    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.

    MICA rather functions as a stress-induced ligand (as a danger signal) for integral membrane protein receptor NKG2D ("natural-killer group 2, member D"). MICA is broadly recognized by NK cells, γδ T cells, and CD8 + αβ T cells which carry NKG2D receptor on their cell surface and which are activated via this interaction. [7]

  5. List of human cell types - Wikipedia

    en.wikipedia.org/wiki/List_of_human_cell_types

    The Human Cell Atlas project, which started in 2016, had as one of its goals to "catalog all cell types (for example, immune cells or brain cells) and sub-types in the human body". [13] By 2018, the Human Cell Atlas description based the project on the assumption that "our characterization of the hundreds of types and subtypes of cells in the ...

  6. Killer-cell immunoglobulin-like receptor - Wikipedia

    en.wikipedia.org/wiki/Killer-cell_immunoglobulin...

    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 ...

  7. Adaptive NK cell - Wikipedia

    en.wikipedia.org/wiki/Adaptive_NK_cell

    An adaptive natural killer (NK) cell or memory-like NK cell is a specialized natural killer cell that has the potential to form immunological memory. [ 1 ] [ 2 ] They can be distinguished from cytotoxic NK (cNK) cells by their receptor expression profile and epigenome. [ 3 ]

  9. Natural killer T cell - Wikipedia

    en.wikipedia.org/wiki/Natural_killer_T_cell

    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 ...
