不要抠鼻子

New research suggests that picking your nose could increase your risk of developing Alzheimer’s disease and related dementia.

Bacteria can travel through the nasal cavity’s olfactory nerve — streamlined through a pick — reach the brain and create markers that are “a tell-tale sign of Alzheimer’s disease,” according to scientists from Australia’s Griffith University.

Specifically, their study, published in Scientific Reports, observed the bacteria Chlamydia pneumoniae — a germ linked to respiratory infections including pneumonia — use the olfactory nerve as “an invasion path to assault the central nervous system.” Cells in the brain then responded to the attack by depositing amyloid beta protein, a hallmark of Alzheimer’s.

“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 Alzheimer’s disease,” professor James St. John, the study’s co-author and head of the Clem Jones Center for Neurobiology and Stem Cell Research, said in a press release.

While the study was conducted on mice, St. John said “the evidence is potentially scary for humans as well.”

The olfactory nerve serves as an express route for bacteria to reach the brain as it bypasses the blood-brain barrier, according to the researchers. Their next phase of research, they said, is aimed at proving the same pathway exists in humans.

“We need to do this study in humans and confirm whether the same pathway operates in the same way. It’s research that has been proposed by many people, but not yet completed,” St. John said.

要勤抠鼻子，顺便还能把大脑里的细菌也抠出来，一举两得，一石二鸟。
