Cells are constantly exposed to mechanical forces that play a role in modulating
cellular structure and function. The cardiovascular system experiences physical
forces in the form of shear stress and stretch associated with blood flow and
contraction, respectively. These forces are sensed by endothelial cells and
cardiomyocytes and lead to responses that control vascular and cardiac
homeostasis. This was highlighted at the Pan American Physiological Society
meeting at Iguassu Falls, Brazil, in a symposium titled "Mechanosignaling in the
Vasculature." This symposium presented recent research that showed the existence
of a vital link between mechanosensing and downstream redox sensitive signaling
cascades. This link helps to transduce and transmit the physical force into an
observable physiological response. The speakers showcased how mechanosensors such
as ion channels, membrane receptor kinases, adhesion molecules, and other
cellular components transduce the force via redox signals (such as reactive
oxygen species and nitric oxide) to receptors (transcription factors, growth
factors, etc.). Receptor activated pathways then lead to cellular responses
including cellular proliferation, contraction, and remodeling. These responses
have major relevance to the physiology and pathophysiology of various
cardiovascular diseases. Thus an understanding of the complex series of events,
from the initial sensing through the final response, is essential for progress in
this field. Overall, this symposium addressed some important emerging concepts in
the field of mechanosignaling and the eventual pathophysiological responses.
