Tengrinews.kz - Scientists from Griffith University in Australia have discovered an unexpected mechanism in which bacteria, entering the brain through damaged nasal tissues, can trigger processes characteristic of Alzheimer's disease. The study was published in the journal Scientific Reports, according to Gazeta.Ru.
In experiments on mice, researchers found that the bacteria Chlamydia pneumoniae, which can cause pneumonia, enters the brain via the olfactory nerve. This process is intensified when the tissues in the nasal cavity are damaged.
In response to the infection, amyloid-beta proteins, which accumulate in Alzheimer's disease, began to form in the brains of the mice. Although the research was conducted on animals, its findings raise concerns about potential risks to humans.
"We have for the first time proven that Chlamydia pneumoniae can directly enter the brain through the nasal cavity, causing pathological changes similar to the signs of Alzheimer's disease," said Dr. James St. John, one of the authors of the study.
Despite the need for further research on humans, scientists are already advising people to avoid picking their noses and plucking nasal hairs, as these habits can damage the protective tissues in the nose.
According to the researchers, their discovery highlights the importance of studying the role of bacteria and viruses in the development of neurodegenerative diseases. Every step along this path brings humanity closer to understanding and preventing complex conditions like Alzheimer's disease.
