Il 23. It is produced by antigen presenting cells and has been shown to promote the production and survival of a distinct lineage of T-cells called TH17 cells. IL-23 and IL-12 have different receptors and different effects. IL-23 binds to a heterodimeric receptor complex composed of IL12RB1 and IL23R, activates the Jak-Stat signaling cascade, stimulates memory rather than naive T-cells and promotes.

When IL-23 binds to IL-23 Bioassay Cells, the receptor transduces intracellular signals resulting in luminescence. These cells derive from the human embryonic kidney HEK293 cell line. IL-23 is secreted by dendritic cells and macrophages, is involved in TH17 cell differentiation in a pro-inflammatory setting, and induces proliferation of memory T-cells.

In this study, we show that a deficiency of the p19 component of IL-23 in the autoimmune BXD2 (BXD2-p19-/-) mouse leads to a shift of the follicular T helper cell program from follicular T helper (Tfh)-IL-17 to Tfh-IFN-γ.Although the germinal center (GC) size and the number of GC B cells.
