  2. Macrophage - Wikipedia

    en.wikipedia.org/wiki/Macrophage

    The activation of T H 1 and M1 macrophage is a positive feedback loop, with IFN-γ from T H 1 cells upregulating CD40 expression on macrophages; the interaction between CD40 on the macrophages and CD40L on T cells activate macrophages to secrete IL-12; and IL-12 promotes more IFN-γ secretion from T H 1 cells.

  3. Phagocyte - Wikipedia

    en.wikipedia.org/wiki/Phagocyte

    A macrophage's location can determine its size and appearance. Macrophages cause inflammation through the production of interleukin-1, interleukin-6, and TNF-alpha. [75] Macrophages are usually only found in tissue and are rarely seen in blood circulation. The life-span of tissue macrophages has been estimated to range from four to fifteen days ...

  4. Macrophage polarization - Wikipedia

    en.wikipedia.org/wiki/Macrophage_polarization

    Macrophage polarization is a process by which macrophages adopt different functional programs in response to the signals from their microenvironment. This ability is connected to their multiple roles in the organism: they are powerful effector cells of the innate immune system, but also important in removal of cellular debris, embryonic development and tissue repair.

  5. Regulatory macrophages - Wikipedia

    en.wikipedia.org/wiki/Regulatory_macrophages

    Regulatory macrophages (Mregs) represent a subset of anti-inflammatory macrophages. In general, macrophages are a very dynamic and plastic cell type and can be divided into two main groups: classically activated macrophages (M1) and alternatively activated macrophages (M2). [1] M2 group can further be divided into sub-groups M2a, M2b, M2c, and ...

  6. Cell fusion - Wikipedia

    en.wikipedia.org/wiki/Cell_fusion

    Cell fusion is an important cellular process in which several uninucleate cells (cells with a single nucleus) combine to form a multinucleate cell, known as a syncytium.Cell fusion occurs during differentiation of myoblasts, osteoclasts and trophoblasts, during embryogenesis, and morphogenesis.

  8. Dermal macrophage - Wikipedia

    en.wikipedia.org/wiki/Dermal_macrophage

    An electron micrograph of a macrophage. This is the general morphology of macrophages. The anatomy of human skin. Dermal macrophages are usually present in the dermis and around hair follicles. Dermal macrophages are macrophages in the skin that facilitate skin homeostasis by mediating wound repair, hair growth, and salt balance. [1]

  9. Monocyte - Wikipedia

    en.wikipedia.org/wiki/Monocyte

    In general, monocytes and their macrophage and dendritic cell progeny serve three main functions in the immune system. These are phagocytosis , antigen presentation, and cytokine production. Phagocytosis is the process of uptake of microbes and particles followed by digestion and destruction of this material.
