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 ...
T cells are one of the important types of white blood cells of the immune system and play a central role in the adaptive immune response. T cells can be distinguished from other lymphocytes by the presence of a T-cell receptor (TCR) on their cell surface. T cells are born from hematopoietic stem cells, [1] found in the bone marrow.
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]
Skeletal muscle regeneration in the site of injury accumulates T-reg cells as a response to IL-33. T-reg cells directly induce M1/M2 phenotype of macrophages so they change the outcome and manage the processes in time. Another important function od T-regs is their activation of muscle cells precursors and proliferation of these cells by growth ...
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.
Smooth muscle cells are spindle-shaped with wide middles, and tapering ends. They have a single nucleus and range from 30 to 200 micrometers in length. This is thousands of times shorter than skeletal muscle fibers. The diameter of their cells is also much smaller which removes the need for T-tubules found in striated muscle cells. Although ...

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]
