Australian researchers have shown that bacteria can travel through the olfactory nerve in the nose and into the brain of mice, where it creates markers that are a“We’re the first to show that Chlamydia pneumoniae can go directly up the nose and into the brain where it can set off pathologies that look like,” said James St John, who heads the Clem Jones Centre for Neurobiology and Stem Cell Research at Griffith University.
The cells in the brain then responded by depositing amyloid beta protein, which is a hallmark of Alzheimer’s disease. According to the researchers, the olfactory nerve in the nose is directly exposed to air and offers a short pathway to the brain, one which bypasses the blood-brain barrier. That makes it an easy pathway to the brain for viruses and bacteria.
Professor St John said further research was needed to see whether the pathway operated the same way in humans as mice.“What we do know is that these same bacteria are present in humans, but we haven’t worked out how they get there.”
