Discovery of ‘hot pepper’ receptor in heart may explain chest pain, lead to new treatments
The secret to heart attack chest pain may be on the tip of your tongue.
Although they may seem unlikely bedfellows, Penn State College of Medicine researchers found evidence to suggest that the same type of nerve receptors that register the burning sensation from hot peppers in the mouth may cause the sensation of chest pain from a heart attack.
"Our study is the first to demonstrate that the hot pepper receptor exists on the heart and may be responsible for triggering heart attack chest pain," said Hui-Lin Pan, M.D., Ph.D., professor of anesthesiology, Penn State College of Medicine. "Until now, the capsaicin, or hot pepper receptor, was only known for sensing heat and pain from the skin. Our data suggest that the hot pepper receptors could become a new target for treatment of some types of chronic chest pain, such as angina pectoris, that are resistant to other treatments." The study, titled "Cardiac vanilloid receptor 1-expressing afferent nerves and their role in the cardiogenic sympathetic reflex in rats," was published today (Sept. 1) in the Journal of Physiology, accompanied by an editorial article discussing the importance of the study.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
