  2. Macrophage - Wikipedia

    en.wikipedia.org/wiki/Macrophage

    In humans, dysfunctional macrophages cause severe diseases such as chronic granulomatous disease that result in frequent infections. Beyond increasing inflammation and stimulating the immune system, macrophages also play an important anti-inflammatory role and can decrease immune reactions through the release of cytokines.

  3. Alveolar macrophage - Wikipedia

    en.wikipedia.org/wiki/Alveolar_macrophage

    Micrograph showing hemosiderin-laden alveolar macrophages, as seen in a pulmonary hemorrhage. H&E stain. An alveolar macrophage, pulmonary macrophage, (or dust cell) is a type of macrophage, a professional phagocyte, found in the airways and at the level of the alveoli in the lungs, but separated from their walls. [1]

  4. 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 ...

  5. Legionella pneumophila - Wikipedia

    en.wikipedia.org/wiki/Legionella_pneumophila

    Upon entry to the human respiratory tract, L. pneumophila is able to infect and reproduce within human alveolar macrophages. [4] This causes the onset of Legionnaires' disease, also known as legionellosis. [4] Infected humans may display symptoms such as fever, delirium, diarrhea, and decreased liver and kidney function. [6]

  6. Mononuclear phagocyte system - Wikipedia

    en.wikipedia.org/wiki/Mononuclear_phagocyte_system

    Macrophages are diffusely scattered in the connective tissue and in liver (Kupffer cells), spleen and lymph nodes (sinus histiocytes), lungs (alveolar macrophages), and central nervous system (microglia). The half-life of blood monocytes is about 1 day, whereas the life span of tissue macrophages is several months or years.

  7. Foreign-body giant cell - Wikipedia

    en.wikipedia.org/wiki/Foreign-body_giant_cell

    Through the release of Interleukin 4 (IL-4) and Interleukin 13 (IL-13) by TH2, or T helper cells, and mast cells, these macrophages can fuse to form foreign body giant cells. [1] [4] The macrophages are initially attracted to the injury/infection site through a variety of chemoattractants like growth factors, platelet factors, and interleukins. [4]

    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]
