Next, the scientists plan to examine where in the brain these pathways converge, and then explore the parts of the brain that receive signals that determine the decision of whether to scratch an itch.

We found that if you sensitize one pathway, you can stimulate a pathological itch state, and vice versa,” says Han. “This indicates that these two pathways act together to drive chronic itch.” Next, ...

A class of spinothalamic tract neurons is selectively excited by stimuli that cause itch, suggesting that this sensation is mediated by distinct peripheral and central pathways.

Not all itches are the same, according to the brain Discovery that distinct brain pathways underlie itch-scratch responses and chronic itch conditions in mice paves the way for new therapeutic targets ...

However, they further noted, “Whereas IL-31–dependent itch-sensory pathways have been well characterized, the contributions of IL-31 to cutaneous inflammation remain unclear.” ...

But whether this pathway explains contagious itching in humans has yet to be seen, says Gil Yosipovitch at the University of Miami Miller School of Medicine in Florida.

Then, they performed additional experiments in mouse models and found removal of IL-3 or GD3 cells, as well as blocking its ...

“We could block itch, by blocking this pathway,” Chiu said. Until now, researchers thought the link between bacteria and itch was indirect. “We thought it was A to B to C, ...

Scientists found a molecular pathway that triggers allergic itching from pollen, dust mites, and more. By Laura Baisas. Published Sep 4, 2024 11:00 AM EDT.

Itch is a protective signal that animals use to prevent parasites from introducing potentially hazardous pathogens into the body. If a mosquito lands on a person’s arm, they sense its presence on ...
