Found bacteria that the human immune system has never encountered before

A joint study by scientists has shown that there are some bacteria that are so foreign to

human that immune cells cannotregister. The new discovery at least casts doubt on the long-standing theory of universal immunity. According to her, human cells can recognize, if necessary, any bacteria with which they interact. However, research has shown that some bacteria are determined solely by their environment or local habitat. The results of a new study published in the journal Science Immunology.

A group of scientists had to look deeper than3,000 m below the surface of the Earth to find such alien bacteria for humans. They will help scientists better understand how the human immune system reacts to completely foreign organisms.

“Our team has discovered and cultivated newbacteria that are completely immune to the human immune system, ”said Randy Rotian, assistant professor of biology at the New York State College of Arts and Sciences and co-author of the article. He stresses that the bacteria have not elicited any reaction from the human innate immune system. According to Rotian, this discovery was unexpected for scientists.

This study is the culmination of a five-yearresearch carried out over 3,704 km (2,000 nautical miles) in the central Pacific Ocean. Scientists have sequenced thousands of genes, doing most of the work in the floating laboratory.
