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.[6]
VEGF-B plays also an important role on several types of neurons. It is important for the protection of neurons in the
retina[7] and the
cerebral cortex during
stroke,[8] and of
motor neurons during
motor neuron diseases such as
amyotrophic lateral sclerosis.[9]
VEGF-B exerts its effects via the
FLT1 receptor.[10] But the role of
co-receptorNRP in VEGF-B-mediated effects is still unclear.[11]
VEGF-B has also been found to control
endothelial uptake and transport of fatty acids in heart and skeletal muscle.[12][13]
