Should you scratch that itchy? Science has a surprising answer

“Happiness is scratching for every scab”, itching often worsens the skin’s condition. So why is instinct so strong?

In a study with the mice, researchers of Pittsburgh University can be developed to fill in the so-called inflammation and puffiness and why people and other animals will be the so-called “Itching period”. According to yieldIt was published today ScienceTo trigger anchuring antibacterial inflammation, creates a surprising finding with potential significant effects for the treatment of inflammatory skin conditions.

“First, these findings introduced a paradox: If it’s bad for us to scratch a sheet, why does it feel so good?” Daniel Kaplan, University of Pittsburgh, said he lived in a university statement. “Scroll is often pleasant, it should also provide a kind of benefit to develop. Our research helps resolve this paradox, proving that this paradox protects against bacterial skin infections.”

The University of Pittsburgh was led by Andrew Liu, researchers aggravate the situation, which causes allergen or skin irritants to itching rashes and leaping. They caused symptoms in normal mice, as well as the mice, as well as neurons that feel itching.

When normal mice scratch their ears, the supplements are filled with swollen and filled with neutrophils (inflammatory immune cells). Some normal mice are like a dog’s scratch and their ears with mice “a dog’s” silly inflammation and swelling “in the consequences, unfortunately, your parents are justified: scratches it worse .

Cells, which are known as the cells, which are known as the cells in the mast cells to trigger the mast cells in the mast cells to trigger the mast cells of researchers, pains that are pain-feeling.

“In the contact dermatitis, the mast cells are directly active by allergens who drive small inflammation and itching,” Kaplan said. “In response, the release of the substance activates the first road mast cells, so the reason for scratching is to trigger more inflammation in the skin, because mast cells consist of two ways (collective).”

Mast cells are behind various undesirable skin conditions, but they are involved to protect us from pathogens. In fact, researchers have caused a decrease in scratch Staphylococci aureus (Preliminary bacteria in charge of skin infections in skin).

“Finding the charm improves protection Staphylococcus aureus Some contexts suggest that it can be useful, “Kaplan.” But the damage to scratch damage is probably chronic of it, it benefits this benefit. “

Through the role of mast cells inside the curved era, the education may have a strong impact on future treatment for inflammatory skin conditions. Also, he also reminds you that there is no worse than you have itchy …
