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.

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 ...
In biological research, experiments or tests are often used to study predicted causal relationships between two phenomena. [1] These causal relationships may be described in terms of the logical concepts of necessity and sufficiency. Consider the statement that a phenomenon x causes a phenomenon y.
Whole-cell pertussis vaccine stimulates natural infection better than the acellular pertussis vaccine. [4] [5]Even though cell-mediated immunity persists in patients received with the acellular pertussis vaccine, stronger lymphocytic proliferation, specifically memory T helper 1 cell and T helper 17 cells and cytokine responses are observed in patients received with the whole cell pertussis ...
The premature expression of BLIMP-1 in primary B cells results in cell death, so only cells that are ready to initiate transcription driven by BLIMP-1 are able to survive and differentiate. [ 5 ] [ 13 ] However, without BLIMP-1, proliferating B cells are unable to differentiate to plasma cells, resulting in severe reduction in production of all ...
Parabiosis is a laboratory technique used in physiological research, derived from the Greek word meaning "living beside." The technique involves the surgical joining of two living organisms in such a way that they develop a single, shared physiological system.
ITAMs are important for signal transduction, mainly in immune cells. They are found in the cytoplasmic tails of non-catalytic tyrosine- phosphorylated receptors [ 7 ] such as the CD3 and ζ-chains of the T cell receptor complex, the CD79 -alpha and -beta chains of the B cell receptor complex, and certain Fc receptors .
