Abstract: TSLP Produits

Synonymes: TSLP Protein, thymic stromal lymphopoietin Protein, TSLP Protein, Tslp Protein

Sujet: TSLP is a hemopoietic protein that is expressed in the heart, liver and prostate. TSLP overlaps biological activities with IL-7 and binds with the heterodimeric receptor complex consisting of the IL-7R alpha chain (IL-7Rª) and the TSLP-specific chain (TSLPR). Like IL-7, TSLP induces phosphorylation of STAT3 and STAT5, but uses kinases other than the JAKs for activation. TSLP prohibited apoptosis and stimulated growth of the human acute myeloid leukemia (AML)-derived cell line MUTZ3. It induces the release of T cell-attracting chemokines TARC and MDC from monocytes and activates CD11c(+) dendritic cells (DCs). TSLP activated DCs primed naive T cells to produce the proallergic cytokines (IL-4, IL-5, IL-13, TNFª) while down-regulating IL-10 and IFN-γ suggesting a role in initiating allergic inflammation. Synonym: Thymic Stromal Lymphopoietin ( TSLP), Human. Formulation: Lyophilized from a 0.2µm filtered concentrated solution in 20mM PB, pH 7.4, 150mM NaCl.

Poids moléculaire: Approximately 15.0 KDa, a single non-glycosylated polypeptide chain containing 132 amino acids.
