Fms-related tyrosine kinase 3 ligand (FLT3LG) is a hematopoietic four helical bundle cytokine. It is structurally homologous to stem cell factor (SCF) and colony stimulating factor 1 (CSF-1). In synergy with other growth factors, such as IL-7 and IL-3, Flt-3 ligand promotes long-term expansion and differentiation of human pro-B-cells.1,2 Flt3 ligand is a cytokine capable of inducing large numbers of dendritic cells that dramatically enhances the sensitivity of antigen-specific B and T cell responses to systemic injection of a soluble protein. Through a CD40-CD40 ligand-dependent mechanism Flt-3 Ligand influences the class of antibody produced and enables productive immune responses.3
