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.

Subsequently, the primed cells will differentiate either into effector cells or into memory cells that can mount stronger and faster response to second and upcoming immune challenges. [2] T and B cell priming occurs in the secondary lymphoid organs (lymph nodes and spleen). Priming of naïve T cells requires dendritic cell antigen presentation.
Haruko Obokata claimed that STAP cells were produced by exposing CD45 + murine spleen cells to certain stresses including an acidic medium with a pH of 5.7 for half an hour. [6] [7] Following this treatment, the cells were verified to be pluripotent by observing increasing levels of Oct-4 (a transcription factor expressed in embryonic stem cells) over the following week using an Oct4-GFP ...
Additional populations of memory T cells are now known to exist. These include tissue-resident memory T (Trm) cells and virtual memory T cells. [35] The single unifying theme for all memory T cell subtypes is that they are long-lived and can expand quickly to large numbers of effector T cells upon encountering their cognate antigen.
The theory accounts for the ability of T cells to have regulatory roles in both helping and suppressing immune responses. In 1976 Murphy et al. and Tada et al. independently reported a phenomenon in mice called I-J. [17] [18] From the perspective of the symmetrical network theory, I-J is one of the most important phenomena in immunology, while for many immunologists who are not familiar with ...
A Time Reversal Mirror (TRM) is a device that can focus waves using the time reversal method. TRMs are also known as time reversal mirror arrays since they are usually arrays of transducers. TRM are well-known and have been used for decades in the optical domain. They are also used in the ultrasonic domain.
Serial passage is the process of growing bacteria or a virus in iterations. For instance, a virus may be grown in one environment, and then a portion of that virus population can be removed and put into a new environment.
