Les lymphocytes Th9

Inflammed skin harbours Th9 cells.

Various effector CD4 + T-lymphocyte subsets have been characterized, such as T-helper (Th)1, Th2, regulatory CD4 + T cells (Treg), Th17, and Th22, which show distinct patterns of cytokine release. Specifically, the cytokine interleukin (IL)-9 has been regarded largely as an exclusive Th2 cytokine. However, a new subset of the Th population, named " Th9 " , which is separate from Th2, producing ...

Th9 cells: differentiation and disease.

CD4(+) T-helper cells regulate immunity and inflammation through the acquisition of potential to secrete specific cytokines. The acquisition of cytokine-secreting potential, in a process termed T-helper cell differentiation, is a response to multiple environmental signals including the cytokine milieu. The most recently defined subset of T-helper cells are termed Th9 and are identified by the ...

STAT6-dependent regulation of Th9 development.

Th cell effector subsets develop in response to specific cytokine environments. The development of a particular cytokine-secreting pattern requires an integration of signals that may promote the development of opposing pathways. A recent example of this paradigm is the IL-9-secreting Th9 cell that develops in response to TGF-β and IL-4, cytokines that, in isolation, promote the development of i...

Les Rotations Et Les Quaternions

La construction du corps non commutatif H de quaternions est une variante plus compliquée de la construction du corps commutatif C de nombres complexes. Donc on commence en rappelant la construction de C à partir de R. Les nombres complexes s’écrivent a+ bi avec a, b ∈ R. Donc C est un espace vectoriel sur R de dimension 2 avec base {1, i}. La loi d’addition de C est celle que C possède en tant...
