In contrast to VEGF-A, VEGF-B plays a less pronounced role in the vascular system: Whereas VEGF-A is important for the formation of blood vessels, such as during development or in pathological conditions, VEGF-B seems to play a role only in the maintenance of newly formed blood vessels during pathological conditions.[2]
VEGF-B plays also an important role on several types of neurons. It is important for the protection of neurons in the retina[3] and the cerebral cortex during stroke[4] and of motoneurons during motor neuron diseases such as amyotrophic lateral sclerosis.[5]
VEGF-B exerts its effects via the FLT1 receptor.[6]
VEGF-B has also been found to control endothelial uptake and transport of fatty acids in heart and skeletal muscle.[7][8]
Interactions
Vascular endothelial growth factor B has been shown to interact with FLT1.[9][10]
