Every hole in your face is a walled garden

Your skin is home to thousands of bacteria, and the ways in which it contributes to skin health are still very mysterious. This mystery may be getting more complicated by the fact that it was published on Thursday in an article published in the journal Cell host and microbes, Researchers study many types Cutibacterium acnes In 16 human volunteers, the bacteria found that each hole was for its own world. Each hole contains only one type C. Acne.

C. Acne It is found naturally, and has a lot of bacteria on the skin. Tammy Liberman, a professor at Massachusetts Institute of Technology and author of the new paper, says the link between acne and skin disease is unclear. If biologists want to open up the relationship between the people in front of you and their health, it is important to understand the different types of species. C. Acne They have their own talents or secrets and how the stress spreads through your skin.

To collect their specimens, Liberman and colleagues used comedian extractors and old-fashioned compresses. Then, in each of the holes in Petri’s plates, he painted a small sample of ice cubes. Samples from toothpaste were sprayed on participants’ foreheads, cheeks, and back, collecting bacteria that lived on the surface of the skin rather than in the pores. They allow the bacteria to grow, then take their DNA in order to identify them.

Each person’s skin had a unique combination of species, but the researchers were surprised to find that each hole contained the same species. C. Acne. The holes were also different from their neighbors – for example, there was no clear design that unites the left cheek or forehead on volunteers.

Moreover, according to chronological data, the bacteria in each hole are basically the same.

“There is a difference of more than 1 square centimeter in your face,” said post-doctoral researcher and lead author Arolline Conwell. But there is a general lack of diversity in one of your holes.

Each hole that scientists think is being created contains the seeds of an individual. According to Liberman, the holes have deep, narrow cracks in the underlying oil glands. if so C. Acne The cell can go down there, it can expand until it fills the hole with its own copies.

This explains why stress, which does not grow rapidly, does not compete with the immediate stress of the same person. They do not compete with each other; They live side by side in their own backyards.

Surprisingly, these gardens are not very old, scientists think. They estimate that the cells that formed the hole in the study began only a year ago.

What happened to the bacteria that once lived there? Researchers do not know – the immune system may have been destroyed, infected with viruses, or improperly removed from the nose to pave the way for new founders.

Liberman said the discovery had implications for broader microbiological research. The slight swaying of a person’s skin does not indicate any complications not covered in this study, e.g. And when scientists consider the possibility of using our microbes to treat disease, the patterns described in this study point to the need for information not only about the environment and identity of microbes but also about the organization of microbes. In the future, doctors may need to clean their pores first if they hope to replace the skin.

How does the bacteria in each hole come and go? Does another resident play a role on our face?

“We have termites on our faces, which live in pores and eat bacteria,” says Liberman. What role do they play in this ecosystem, as far as the protection of gardens is concerned C. Acne, Not yet determined.
