Cytokines are important in health and disease, specifically in host immune responses to infection, inflammation, trauma, sepsis, cancer, and reproduction. The word comes from the ancient Greek language : cyto , from Greek κύτος, kytos , 'cavity, cell' + kines , from Greek κίνησις, kinēsis , 'movement'.
It has been found in both mice and humans that the signature cytokines for these cells are interferon gamma and lymphotoxin alpha. The main cytokine for differentiation into T H 1 cells is IL-12 which is produced by dendritic cells in response to the activation of pattern recognition receptors. T-bet is a distinctive transcription factor of T H ...
Antigen presentation stimulates T cells to become either "cytotoxic" CD8+ cells or "helper" CD4+ cells.. A cytotoxic T cell (also known as T C, cytotoxic T lymphocyte, CTL, T-killer cell, cytolytic T cell, CD8 + T-cell or killer T cell) is a T lymphocyte (a type of white blood cell) that kills cancer cells, cells that are infected by intracellular pathogens such as viruses or bacteria, or ...
Taken together, DAMPs can be useful therapeutic targets for various human diseases, including cancer and autoimmune diseases. [3] DAMPs can trigger re-epithelialization upon kidney injury, contributing to epithelial–mesenchymal transition, and potentially, to myofibroblast differentiation and proliferation. These discoveries suggest that ...
Lymphotoxin alpha, a member of the tumor necrosis factor superfamily, is a cytokine produced by lymphocytes. LT-α 1-β 2 can interact with receptors such as LT-β receptors. [12] Absence of LT-β on cell surfaces will diminish the ability of LT-α to form LT-α 1-β 2, thus decreasing its effective ability as a cytokine.
Tumor-associated immune cells in the tumor microenvironment (TME) of breast cancer models. Cancer immunology (immuno-oncology) is an interdisciplinary branch of biology and a sub-discipline of immunology that is concerned with understanding the role of the immune system in the progression and development of cancer; the most well known application is cancer immunotherapy, which utilises the ...
Also, one study indicates that JAK1 is needed to carry out signalling for receptors of the cytokines IFNγ, IL-2, IL-4 and IL-10. [22] The JAK-STAT pathway in cytokine receptor signalling can activate STATs, which can bind to DNA and allow the transcription of genes involved in immune cell division, survival, activation and recruitment.
An inflammatory cytokine is a type of cytokine (a signaling molecule) that is secreted from immune cells and certain other cell types that promotes inflammation. Inflammatory cytokines are predominantly produced by T helper cells ( T h ) and macrophages and involved in the upregulation of inflammatory reactions. [ 1 ]
