We built a whole-body computational model to study the role of the poorly understood vascular endothelial growth factor (VEGF)
165b
splice isoform in peripheral artery disease (PAD). This model was built and validated using published and new experimental data from cells, mice, and humans, and explicitly accounts for known properties of VEGF
165b
: lack of extracellular matrix (ECM)-binding and weak phosphorylation of vascular endothelial growth factor receptor-2 (VEGFR2) in vitro. The resulting model captures all known information about VEGF
165b
distribution and signaling in human PAD, and provides novel, nonintuitive insight into VEGF
165b
mechanism of action in vivo. Although VEGF
165a
and VEGF
165b
compete for VEGFR2 in vitro, simulations show that these isoforms do not compete for VEGFR2 at much lower physiological concentrations. Instead, reduced VEGF
165a
may drive impaired VEGFR2 signaling. The model predicts that VEGF
165b
does compete for binding to
VEGFR1
, supporting a
VEGFR1
-mediated response to anti-VEGF
165b
. The model predicts a key role for VEGF
165b
in PAD, but in a different way than previously hypothesized.
