    Patients with systemic sclerosis also display hypomethylation of the collagen genes COL23A1 and COL4A2. This overexpression of these collagen genes leads an overproduction of collagen characteristic to tissue fibrosis. The TGF-β signaling pathway and Wnt/β-catenin signaling pathway also play an important role in this disease.

    en.wikipedia.org/wiki/PI3K/AKT/mTOR_pathway

    The PI3K/AKT pathway is crucial in this decision making process. NSCs are able to sense and respond to changes in the brain or throughout the organism. When blood glucose levels are elevated acutely, insulin is released from the pancreas. Activation of insulin receptors activates the PI3K/AKT pathway, which promotes proliferation. [3]

    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 ...

    Anticentromere antibody is more common in the limited form (80–90%) than in the diffuse form (10%), and anti-scl70 is more common in the diffuse form (30–40%) and in African-American patients (who are more susceptible to the systemic form). [27] Other conditions may mimic systemic sclerosis by causing hardening of the skin.

    In cell biology, there are a multitude of signalling pathways. Cell signalling is part of the molecular biology system that controls and coordinates the actions of cells.. Akt/PKB signalling pathway

    Since this activity occurs in the nucleus of the cell ATA is a form of antinuclear antibody. Scleroderma results from the overproduction of collagen in affected tissues, one study claims that there is an increased density of Topoisomerase I sites in the collagen genes, and that the antibodies may be altering transcription at these loci. [ 7 ]

    Examples of feedback control in the PI3K-Akt Pathway. The PI3K-Akt pathway has many downstream effects and must be carefully regulated. One of the ways the pathway is negatively regulated is by reducing PIP 3 levels. Phosphatase and tensin homolog (PTEN) antagonises PI3K by converting PI(3,4,5)P 3 into PI(4,5)P 2.

  9. Autoimmunity - Wikipedia

    en.wikipedia.org/wiki/Autoimmunity

    In immunology, autoimmunity is the system of immune responses of an organism against its own healthy cells, tissues and other normal body constituents. [1] [2] Any disease resulting from this type of immune response is termed an "autoimmune disease".
