Flt-3 Ligand is an alpha-helical cytokine that promotes the differentiation of multiple hematopoietic cell lineages. Flt-3 Ligand is expressed as a noncovalently-linked dimer by T cells and bone marrow and thymic fibroblasts. It is an endogenous small molecule that functions as a cytokine and growth factor that increases the number of immune cells (lymphocytes (B cells and T cells)) by activating the hematopoietic progenitors. It acts by binding to and activating FLT3 (CD135) which is found on what (in mice) are called multipotent progenitor (MPP) and common lymphoid progenitor (CLP) cells. It also induces the mobilization of the hematopoietic progenitors and stem cells in vivo which may help the system to kill cancer cells. FLT3L is crucial for steady-state plasmacytoid dendritic cell (pDC) and classical dendritic cell (cDC) development. A lack of FLT3L results in low levels of dendritic cells.
