  2. Kallikrein - Wikipedia

    en.wikipedia.org/wiki/Kallikrein

    Distinct from plasma kallikrein, tissue kallikreins (KLKs) are expressed throughout the human body and perform various physiological roles. As some kallikreins are able to catalyse the activation of other kallikreins, several cascades involving these proteases have been implicated in the regulation of homeostatic functions.

  3. Systemic scleroderma - Wikipedia

    en.wikipedia.org/wiki/Systemic_scleroderma

    Systemic scleroderma, or systemic sclerosis, is an autoimmune rheumatic disease characterised by excessive production and accumulation of collagen, called fibrosis, in the skin and internal organs and by injuries to small arteries. There are two major subgroups of systemic sclerosis based on the extent of skin involvement: limited and diffuse ...

  4. Immunologic checkpoint - Wikipedia

    en.wikipedia.org/wiki/Immunologic_checkpoint

    An immune checkpoint regulator is a modulator of the immune system, that allows initiation of a productive immune response and prevents the onset of autoimmunity. Examples of such a molecule are cytotoxic T-lymphocyte antigen 4 (CTLA-4 or CD152), which is an inhibitory receptor found on immune cells and programmed cell death 1 (CD279), which has an important role in down-regulating the immune ...

  5. mTOR - Wikipedia

    en.wikipedia.org/wiki/MTOR

    Scleroderma, also known as systemic sclerosis, is a chronic systemic autoimmune disease characterised by hardening (sclero) of the skin (derma) that affects internal organs in its more severe forms. [ 159 ] [ 160 ] mTOR plays a role in fibrotic diseases and autoimmunity, and blockade of the mTORC pathway is under investigation as a treatment ...

  6. 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.

  7. Immunological synapse - Wikipedia

    en.wikipedia.org/wiki/Immunological_synapse

    The process of formation begins when the T-cell receptor binds to the peptide:MHC complex on the antigen-presenting cell and initiates signaling activation through formation of microclusters/lipid rafts. Specific signaling pathways lead to polarization of the T-cell by orienting its centrosome toward the site of the immunological synapse. The ...

  8. Anti-topoisomerase antibodies - Wikipedia

    en.wikipedia.org/wiki/Anti-topoisomerase_antibodies

    Anti Scl-70 antibodies (also called anti-topoisomerase I after the type I topoisomerase target [1]) is a type of antinuclear autoantibody seen mainly in diffuse systemic scleroderma, but is also seen the more limited form of systemic scleroderma called CREST syndrome. [2]

  9. Scleroderma - Wikipedia

    en.wikipedia.org/wiki/Scleroderma

    As of 2012, the five-year survival rate for systemic scleroderma was about 85%, whereas the 10-year survival rate was just under 70%. [43] This varies according to the subtype; while localized scleroderma rarely results in death, the systemic form can, and the diffuse systemic form carries a worse prognosis than the limited form.
