Compared with steady flow with similar time-averaged magnitudes, pulsatile flow stimulates Erk activity more strongly Kadohama et al. Comparison of proinflammatory oscillatory flow with anti-inflammatory pulsatile-flow patterns at atherosclerosis-prone versus atherosclerosis-resistant sites in the human carotid artery identified specific frequency components that exerted pro- or anti-inflammatory effects Feaver et al. Of clinical interest, left ventricle assist devices for heart failure patients generate nonpulsatile flow that induces arterial-venous malformations Islam et al. Erk may mediate these effects, since it is strongly linked to arterial specification Deng et al.
These results imply that endothelial mechanosensors must decode subsecond-frequency characteristics, which necessitates rapid rates of both activation and inactivation. These kinetics, particularly the required inactivation rates, exclude even G protein signaling; however, ion channels can have very rapid activation and inactivation kinetics. Mechanosensitive Piezo channels have very rapid activation and inactivation rates Coste et al. The correlation between atherosclerosis-prone regions of arteries and disturbed flow led to the idea that oscillatory shear, where flow reverses during part of the cardiac cycle, promotes plaque formation Ku et al.
But how ECs sense flow direction is very poorly understood.
Interestingly, ECs in athero-prone regions fail to elongate and align in the direction of flow, and cells therefore experience flow at many angles, including perpendicular, whereas in athero-resistant regions of blood vessels, flow is parallel to the cell axis. In fact, recent studies suggest that plaque localization correlates more strongly with the perpendicular or transverse wall shear stress component than with oscillations Peiffer et al. These effects correlate with the ability of steady laminar or unidirectional pulsatile FSS to induce cell elongation and alignment in the flow direction in conjunction with suppression of inflammation, whereas low or oscillatory flow fails to induce alignment and promotes inflammatory pathways Mohan et al.
The fortuitous observation that the proteoglycan syndecan 4 Sdc4 is required for EC alignment in flow provided a way to test this idea. Yet in vitro, Sdc4 was not required for other flow responses, and thus appears to be specifically required for sensing flow direction, which is separable from sensing flow magnitude. Together, these results demonstrate that loss of alignment is causal for athero-susceptibility and that Sdc4 is a component of the flow direction sensor.
Hemodynamic forces control vessel specification and maturation during development and continue to regulate vessel remodeling during postnatal and adult life. The exquisite ability of ECs to sense multiple aspects of fluid shear stress patterns allows them to coordinate the complex ballet of events involving different cell types and signaling pathways, to constantly adjust vessel structure and function.
Identifying molecular mechanosensors behind the distinct sensing of FSS magnitude, direction, and pulsatility are major directions for future research. Further, characterizing how downstream signaling pathways and gene regulation events are integrated in the context of growth and disease is required to better understand the amazing plasticity of our blood vessels.
The finely tuned biomechanical responses discussed here govern health and disease in nearly every tissue from our first to our last heartbeat.
