  2. Tissue-resident memory T cell - Wikipedia

    en.wikipedia.org/wiki/Tissue-resident_memory_T_cell

    T RM cells have tissue residency-promoting transcriptional signature with features specific to individual tissues and features necessary for long-term survival in these tissues. [9] Skin T RM: T RM cells in the skin express cutaneous lymphocyte antigen (CLA) and CCR8 which are skin homing antigens. They have also higher expression of markers ...

  3. T cell - Wikipedia

    en.wikipedia.org/wiki/T_cell

    T cells are grouped into a series of subsets based on their function. CD4 and CD8 T cells are selected in the thymus, but undergo further differentiation in the periphery to specialized cells which have different functions. T cell subsets were initially defined by function, but also have associated gene or protein expression patterns.

  4. Memory T cell - Wikipedia

    en.wikipedia.org/wiki/Memory_T_cell

    Tissue-resident memory T cells (T RM) occupy tissues (skin, lung, gastrointestinal tract, etc.) without recirculating. Some cell surface markers that have been associated with T RM are CD69 and integrin αeβ7 (CD103). [20] However, it is worth noticing that T RM cells found in different tissues express different sets of cell surface markers. [20]

  5. Insulin receptor - Wikipedia

    en.wikipedia.org/wiki/Insulin_receptor

    The insulin receptor (IR) is a transmembrane receptor that is activated by insulin, IGF-I, IGF-II and belongs to the large class of receptor tyrosine kinase. [5] Metabolically, the insulin receptor plays a key role in the regulation of glucose homeostasis; a functional process that under degenerate conditions may result in a range of clinical manifestations including diabetes and cancer.

  6. Insulin signal transduction pathway - Wikipedia

    en.wikipedia.org/wiki/Insulin_signal...

    The effects of insulin vary depending on the tissue involved, e.g., insulin is most important in the uptake of glucose by muscle and adipose tissue. [2] This insulin signal transduction pathway is composed of trigger mechanisms (e.g., autophosphorylation mechanisms) that serve as signals throughout the cell. There is also a counter mechanism in ...

  7. Autoimmune regulator - Wikipedia

    en.wikipedia.org/wiki/Autoimmune_regulator

    Through the action of AIRE, medullary thymic epithelial cells (mTEC) express major proteins from elsewhere in the body (so called "tissue-restricted antigens" - TRA) and T cells that respond to those proteins are eliminated through cell death . Thus AIRE drives negative selection of self-recognizing T cells. [7]

  8. Thymus - Wikipedia

    en.wikipedia.org/wiki/Thymus

    Once mature, T cells emigrate from the thymus to provide vital functions in the immune system. [11] [12] Each T cell has a distinct T cell receptor, suited to a specific substance, called an antigen. [12] Most T cell receptors bind to the major histocompatibility complex on cells of the body.

  9. Mucosal immunology - Wikipedia

    en.wikipedia.org/wiki/Mucosal_immunology

    A large number of immune system cells in the intestines are found in dome-like structures called Peyer’s patches and in small mucosal lymphoid aggregates called cryptopatches. [14] Above the Peyer’s patches is a layer of epithelial cells , which together with the mucus form a barrier against microbial invasion into the underlying tissue.
