Which cells express IL7R?
The IL7R is expressed on naïve T cells and is downregulated following TCR engagement (8, 9, 13-21). T cells then have the capacity to upregulate the IL7R for their continued maintenance (22-24). However, when T cells are continuously stimulated, they fail to re-express the IL7R (15).
What is the function of IL-7?
IL-7 promotes T-cell survival by up-regulating the expression of anti-apoptotic genes; the anti-apoptotic genes Bcl-2 and Mcl-1 (myeloid-cell-leukemia sequence-1) are the major targets in naïve T-cells. The protein products encoded by these genes inhibit the pro-apoptotic proteins Bax and Bak.
What is IL7R marker?
The IL7R gene provides instructions for making a protein called interleukin 7 (IL-7) receptor alpha chain. This protein is one piece of both the IL-7 receptor and the thymic stromal lymphopoietin (TSLP) receptor. These receptors are embedded in the cell membrane of immune system cells.
Do NK cells express IL7R?
Natural killer (NK) cells are similar to ILC1s but are not considered part of the helper ILC subset and generally do not express the IL-7Rα (45).
What is IL-2 and its role in T cell activation after an encounter with the target antigen?
IL-2 enhances activation-induced cell death (AICD). IL-2 also promotes the differentiation of T cells into effector T cells and into memory T cells when the initial T cell is also stimulated by an antigen, thus helping the body fight off infections.
Do NK cells express il7r?
How do I lower my IL-8?
Interestingly, elevated levels of IL-8 in the sputum of cystic fibrosis patients is reduced by either antibiotic therapy or gene therapy with AAVCFTR 6, 7. In certain gene therapy applications inflammation due to the therapy is a problem 8, and addition of an anti-IL-8 treatment may be helpful.
Which interleukin suppresses the activity of IL-2?
Interleukin-10
Interleukin-10, originally identified as an inhibitor of interferon gamma (IFN-γ) and IL-2 synthesis in Th2 cells (26), efficiently inhibits proliferative and cytokine responses in T cells (1) and was shown to mediate both immunological unresponsiveness and the suppression of immune reactions (27).
What is CD27 a marker for?
CD27+ B cells are larger cells with abundant cytoplasm carrying somatic hypermutation, and have an ability to produce immunoglobulin, indicating that CD27 is a memory marker of B cells. The ligation of CD27 yields crucial signals that positively control the entry of B cells into the pathway to plasma cells.
