Covid long: virus persists brain,: This article explores the topic in depth.
However,
Covid long: virus persists brain. Furthermore, :
Research work is underway in the world to understand the causes of syndrome post-Covidalso called Covid longwhich affected 4% of the French adult population at the end of 2022, according to Public Health France. Meanwhile, This syndrome is manifested by a deep fatigueof the neurological disordersof the breathing difficultiesof the headache…
The study of the Institut Pasteur. Therefore, published in the journal “Nature Communications” on July 22, tends to show that the virus of the COVID-19 “Persists in the long term in the brainstem and disturb the activity of neurones“Summarize the researchers in a statement released on Tuesday.
These studied the effects of COVVI-19 infection “in the central nervous system” covid long: virus persists brain, of hamsters. Moreover, “up to 80 days after the acute phase of infection”.
They observed that the “genes linked to the metabolism. the activity of the neurons are deregulated in the brain of these animals, in a similar way to what is happening in Neurodegenerative diseases“, Like the disease of Parkinsonwith a “deregulation of the dopamine route”.
The virus thus seems to have an impact on the production of the dopamine“. Involved in” the regulation of emotions and memory “, explains one of the researchers, Anthony Coleonin the press release.
Analyzes have shown that. despite a low viral load, the virus could continue to infect new cells, seeming to indicate that it could persist “at low noise” in the cerebral trunk.
According to Guilherme Dias de Melothe main author of the study. this “highlights, for the first time in the animal model, the biological consequences long -term “of the COVID-19.
After having identified “a list covid long: virus persists brain, of long-term deregulated genes” by the virus. the researchers will continue their work “in order to understand how the infection induces the loss of function of dopamine neurons,” he said.
Researchers have already found “signs of the persistence of the virus” of the COVVI-19 in the body. “the alteration of the immune response and an autoimmune response”, recalls theWorld Health Organization (WHO)according to which the pandemic killed 20 million people around the world.
