Venuloarteriolar signaling plays a key role in regulating capillary exchange and is impaired by cardiovascular risk factors, contributing to microvascular complications.
Venuloarteriolar signaling helps mediate microvascular function and dysfunction. Mediators produced at venular sites of inflammation appear to constrict arterioles and increase capillary permeability. In contrast, venules beneficially dilate arterioles to enhance capillary flow according to metabolic demand. These mechanisms are altered with cardiovascular risk factors, contributing to microvascular complications.
