  2. Adaptive immune system - Wikipedia

    en.wikipedia.org/wiki/Adaptive_immune_system

    Cytokines produced during innate immune responses are among the activators of adaptive immune responses. [33] Antibodies exert additive or synergistic effects with mechanisms of innate immunity. Unstable HbS clusters Band-3, a major integral red cell protein; [34] antibodies recognize these clusters and accelerate their removal by phagocytic ...

  3. Immune system - Wikipedia

    en.wikipedia.org/wiki/Immune_system

    Helper T cells regulate both the innate and adaptive immune responses and help determine which immune responses the body makes to a particular pathogen. [66] [67] These cells have no cytotoxic activity and do not kill infected cells or clear pathogens directly. They instead control the immune response by directing other cells to perform these ...

  4. Innate immune system - Wikipedia

    en.wikipedia.org/wiki/Innate_immune_system

    The innate immune system or nonspecific immune system [1] is one of the two main immunity strategies in vertebrates (the other being the adaptive immune system). The innate immune system is an alternate defense strategy and is the dominant immune system response found in plants, fungi, prokaryotes, and invertebrates (see Beyond vertebrates). [2 ...

  5. Immunopathology - Wikipedia

    en.wikipedia.org/wiki/Immunopathology

    The immune response to cancer can be categorized into the two main categories as discussed above: innate immunity and adaptive immunity. Innate immunity is the first line of defense against cancer. It consists of non-specific immune cells that can recognize and destroy abnormal cells, including cancer cells. Natural killer (NK) cells, dendritic ...

  6. Immunity (medicine) - Wikipedia

    en.wikipedia.org/wiki/Immunity_(medicine)

    The immune system has innate and adaptive components. Innate immunity is present in all metazoans, [1] immune responses: inflammatory responses and phagocytosis. [2] The adaptive component, on the other hand, involves more advanced lymphatic cells that can distinguish between specific "non-self" substances in the presence of "self".

  7. Nonspecific immune cell - Wikipedia

    en.wikipedia.org/wiki/Nonspecific_immune_cell

    There are two categories to which parts of the immune system are assigned: the non-specific, or innate immune system and the adaptive immune system. The non-specific response is a generalized response to pathogen infections involving the use of several white blood cells and plasma proteins. Non-specific immunity, or innate immunity, is the ...

  8. Pattern recognition receptor - Wikipedia

    en.wikipedia.org/wiki/Pattern_recognition_receptor

    Toll-like receptors were first discovered in Drosophila and trigger the synthesis and secretion of cytokines and activation of other host defense programs that are necessary for both innate or adaptive immune responses. 10 functional members of the TLR family have been described in humans so far. [5]

  9. Immune response - Wikipedia

    en.wikipedia.org/wiki/Immune_response

    In general, there are two branches of the immune response, the innate and the adaptive, which work together to protect against pathogens. Both branches engage humoral and cellular components. The innate branch—the body's first reaction to an invader—is known to be a non-specific and quick response to any sort of pathogen .
