Discovery of the fact that 44% of people were infected with "head-bad virus"

When infected the brainHippocampusThe existence of a virus that affects human's ability to recognize has been reported. According to the survey, 44% of the subjects were infected, the infection route of this virus is unknown, it is "harmless" to the human body.

Chlorovirus ATCV-1 is part of the human oropharyngeal virome and is associated with changes in cognitive functions in humans and mice

Scientists Discover a Virus That Subtly Changes the Brain to 'Makes Humans More Stupid'

This virus was discovered by chance by a joint research between Nebraska University and Johns Hopkins Medical University. Researchers originally had been conducting research for another purpose, but the discovery of DNA matching with the ATCV-1 virus from the throat of a healthy person reported the "virus that makes human's head worse" It led to.

Although ATCV - 1 has been found to be infected with green algae in lakes and ponds, it has been thought that it is not infected by humans, but this time the discovery of "ATCV - 1 infects humans" In addition, it became clear that "infection causes a decrease in cognitive ability".

Since the survey was targeted to 92 healthy subjects, ATCV-1 was taken from the throat of 44% of them, so researchers were able to analyze the processing speed and accuracy of their brain visual information, Measure the span of. As a result, those who collected ATCV - 1 from the throat seemed to have scored 7 to 9 points compared to those who were not collected.

After that, further study was continued, and this time, ATCV-1 was injected into the digestive tract of Mus musculus to observe the influence of the virus. When I injected the ATCV-1 injected mice and the other mouse in a maze, the mice injected with ATCV-1 took time to find the way and at the same time noticed new obstacles and newly made paths The result that it does not pay is observed. It was found that ATCV-1 affected mouse hippocampus, rewriting genes related to memory and learning ability, synaptic plasticity, people infected with ATCV-1 became distracted, spatial recognition ability was also obvious It is considered to decrease.

It was the first time that the existence of microorganisms that affected the human body without attacking the immune system was proved. Professor Robert Yolken who conducted the research said, "This is a remarkable example that 'harmless' microorganisms affect human's behavior and cognitive abilities.Many people are distinguished by genes inherited from parents, but some Changes in the genes are brought about by microorganisms. "

Furthermore, the infection route of ATCV-1 has not been confirmed yet, there is a possibility that infection can not be prevented by the means "Since ATCV-1 exists in the pond, it is not possible to stop swimming". "The discovery of this time is only the beginning.Evola It is a virus that deals damage to the body like leukemia and influenza and leaves, but viruses affecting without damaging the human body in addition to ATCV-1 There should be there, "Yolken says.
