Sujet
Thymic Stromal Lymphopoietin (TSLP) was originally identified as an activity from the conditioned medium of a mouse thymic stromal cell line that promoted the development of B cells. Cytokine that induces the release of T-cell-attracting chemokines from monocytes and, in particular, enhances the maturation of CD11c dendritic cells. Can induce allergic inflammation by directly activating mast cells.
Poids moléculaire
17.8 kDa. Due to glycosylation, the protein migrates to 12 kDa&20-25 kDa based on Tris-Bis PAGE result.
