FMS-like tyrosine kinase 3 ligand

The Flt3l is a small molecule that acts as a growth factor that increases the number of immune cells by activating the hematopoietic progenitors. 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 pDC and cDC development. A lack of FLT3L results in low levels of DCs.
