Understanding the basic science of heart and muscle function could open the door to new treatments. The study examined the electrical impulses that coordinate contraction in heart ... pathway for ...

Further investigation revealed that stimulating the receptors triggers a cascade of molecular events within the heart cells, ...

University of Maryland School of Medicine researchers have uncovered a previously unknown molecular pathway that is critical to understanding cardiac arrhythmia and other heart muscle problems.

Cardiac muscle tissue is only found in your heart. It performs involuntary, coordinated contractions that allow your heart to pump blood through your circulatory system. Cardiac muscle tissue is ...

New pathway to treat heart failure ... The researchers had demonstrated for the first time that contraction of heart muscle cells could be triggered via the beta2-adrenergic receptor, ...

Sweet Taste Receptors in the Heart: A New Pathway for Cardiac Regulation ... they observed a significant increase in the force of heart muscle contraction and accelerated calcium handling ...

PAG influences the force of heart muscle contractions by interacting with beta-2 adrenergic receptors, which may contribute to heart failure. Mutations in parts of these receptors, previously ...

The heart contains "sweet taste" receptors, TAS1R2 and TAS1R3, which, when stimulated by sweet substances like aspartame, enhance heart muscle contraction and calcium handling.

Sweet taste receptors in the heart: A new pathway for cardiac regulation New research shows that the heart can sense sweeteners and can increase the force of heart muscle contraction in response ...
