Abstract
The growing recognition of abundance of oscillating functions in biological systems has motivated this brief overview, which narrows down on the microvasculature. Specifically, it encompasses self-sustained oscillations of blood flow, hematocrit, and viscosity at bifurcations; blood flow effects on the oscillations of endothelial glycocalyx, mechanotransduction, and its termination to prime endothelial cells for the subsequent mechanical signaling event; oscillating affinity of hyaluronan-CD44 binding domain; spontaneous contractility of actomyosin complexes in the cortical actin web and its effects on the tension of the plasma membrane; reversible effects of sirtuin-1 on endothelial glycocalyx; and effects of plasma membrane tension on endo- and exocytosis. Some potential interactions between those oscillators, and their coupling, are discussed together with their transition into chaotic movements. Future in-depth understanding of the oscillatory activities in the microvasculature could serve as a guide to its chronotherapy under pathological conditions.
