Activity summary

The Flt3 ligand (Flt3L) also known as Flt3-L Flt3 ligand protein or flt-3 ligand protein is a small cytokine with a molecular mass of approximately 18 to 19 kDa. It acts as a growth factor by binding to the Flt3 receptor tyrosine kinase on the surface of hematopoietic progenitor cells. Flt3L is expressed in various tissues including the bone marrow where it plays a significant role in hematopoiesis. It is critical in dendritic cell and B cell development impacting the immune response mechanism.

Biological function summary

The Flt3 ligand plays an essential role in the immune system. It is a monomeric cytokine that induces proliferation of early lineage cells within the hematopoietic system. Flt3L does not function as part of a complex but acts independently to stimulate the proliferation differentiation and survival of hematopoietic cells. By interacting directly with its receptor it significantly influences the innate and adaptive immune systems through the maturation of dendritic and B cells.

Pathways

The Flt3 ligand is involved in hematopoietic signaling pathways primarily the PI3K-Akt signaling pathway. This pathway is essential for cell survival and growth where Flt3L aids in transmitting growth signals necessary for hematopoietic cells. Flt3L also interacts with proteins such as FLT3 receptor and influences the downstream signaling cascade affecting cell fate decisions in hematopoiesis and immune cell maturation.

Associated diseases and disorders

Flt3 ligand is connected to leukemia particularly acute myeloid leukemia (AML) due to dysregulation of the FLT3 signaling pathway. Mutations in the FLT3 receptor can lead to uncontrolled cell proliferation contributing to tumorigenesis. Additionally Flt3L plays a role in autoimmune disorders by influencing immune cell development. It is closely connected with the FLT3 receptor and other tyrosine kinases which when mutated can exacerbate disease pathology through abnormal cell signaling and proliferation.
