A study published by the University of Manchester in the United Kingdom showed that some of the wounds that are not easily healed may be associated with a receptor and a bacteria that is present on the skin. This result will help find better ways to improve wound healing in the future.
As you age, some people become difficult to heal after a wound, which can easily lead to worsening infection. In response to this phenomenon, researchers from the University of Manchester and the University of Hull in the United Kingdom used mouse experiments to analyze the reasons.
According to a report published in the American Journal of Dermatology Research, mice lacking a Nod2 receptor have more P. aeruginosa than normal mice, and the former has wound healing ability. Obviously not as good as the latter. This receptor recognizes the different bacterial components on the skin and regulates the body's response to these bacteria, so whether the receptors function properly can affect the bacterial community balance in mice.
The researchers explained that further observations indicate that the bacteria slow down the healing of wounds in normal mice, and in certain cases (such as the lack of Nod2 receptors), it can make wound healing more difficult. The team also said that the findings are equally applicable to humans.
One of the authors of the report, Hannah Krukshank, a scholar at the University of Manchester, said that it is important to find out why the wound is difficult to heal in the future. (Xinhua News Agency)
