T RM cells develop from circulating effector memory T cell precursors in response to antigen. The main role in formation of T RM cells has CD103 and expression of this integrin is dependent on the cytokine TGF-β. CD8 + effector T cells that lack TGF-β fail to upregulate CD103, and subsequently do not differentiate into T RM cells.

TRM can be much larger than it would be if exposed to the same field at room temperature (see isothermal remanence). This remanence can also be very stable, lasting without significant change for millions of years. TRM is the main reason that paleomagnetists are able to deduce the direction and magnitude of the ancient Earth's field. [1]
This glossary of geography terms is a list of definitions of terms and concepts used in geography and related fields, including Earth science, oceanography, cartography, and human geography, as well as those describing spatial dimension, topographical features, natural resources, and the collection, analysis, and visualization of geographic ...
Sentinel cells refer to cells in the body's first line of defense, which embed themselves in tissues such as skin. [1] Sentinel cells represent diverse array of cell types with the capability to monitor the presence of exogenous or potentially harmful particles and play a crucial role in recognizing and sampling signs of infection or abnormal cellular activity and/or death.
In immunology, an immunological synapse (or immune synapse) is the interface between an antigen-presenting cell or target cell and a lymphocyte such as a T cell, B cell, or natural killer cell. The interface was originally named after the neuronal synapse , with which it shares the main structural pattern. [ 1 ]
Most of these members are cell-surface proteins that are characterized by the presence of four hydrophobic domains. The proteins mediate signal transduction events that play a role in the regulation of cell development, activation, growth, and motility. This encoded protein is a cell surface glycoprotein that is known to complex with integrins.
Promiscuous gene expression (PGE), formerly referred to as ectopic expression, is a process specific to the thymus that plays a pivotal role in the establishment of central tolerance.
