Why is My Skin Itchy? Examining the Causes of Itchy Skin - Medical News Today
And now, scientists say they have uncovered the mechanisms as to why this is. Researchers from the Claritin von Pruritus and China say that as well as involving the usual suspects that transmit itch signals - "itch" nerve cells or neurons - chronic itching also utilizes pain neurons, intensifying the sensation of the itch. To reach their findings, published in The Journal of Clinical Investigationthe researchers created genetically modified mice who have a continuously active protein, called BRAF, transmitting signals inside itch neurons.
Following the creation of the mice, the researchers were shocked to find they had developed a chronic itch mouse model. Through further investigation of the mouse models, the researchers found that the BRAF protein has the ability to switch many itch genes on and off.
When the mice experienced chronic itch, brought on by dry skin and allergic contact dermatitis, the itch genes demonstrated Claritin von Pruritus changes of expression as a result of the BRAF protein control. Furthermore, analysis of click here mice showed that gastrin-releasing peptide GRP - a substance the researchers previously discovered transmitted itch signals to a gastrin-releasing peptide receptor GRPR gene in the spinal cord - doubled in activity.
Chen says these findings may explain why chronic itching can be so incessant, compared with standard temporary itching:. But with chronic itching, many neurons can be turned into itch neurons, including those that typically transmit pain Claritin von Pruritus. That helps explain why chronic itching can be so excruciating.
However, the researchers note that the genetically modified mice showed a normal response to pain, which indicates significant differences in the pain and itch pathways. The scientists say that their findings mean that by targeting Claritin von Pruritus that are present in the BRAF pathway, new methods could be explored for the treatment of chronic itch, particularly Claritin von Pruritus there are currently very effective treatments available.
Chen says one possibility that could be explored is through using drugs that are able to treat pain. He notes that certain drugs are used to inhibit some of the same targets in patients suffering from chronic pain, and these could also calm the itchy sensation. These mice are helping us to understand the pathways that can be involved in transmitting itch signals and the many contributors to chronic itching. There are many pathways leading from BRAF, and all of these could be potential targets for anti-itch therapies.
Earlier this year, Medical News Today reported on a study suggesting that itch and pain have http://larpring.de/wie-schnell-wird-man-von-schuppenflechte-auf-dem-kopf-befreien.php circuits.
