A healthy nose
File under Yet Another Microbiome — this one’s in your nose. Apparently (say University of Antwerp microbiologists), than those without it.
The bacteria have adapted to use tiny hairs to anchor themselves inside people’s noses, where they do a body good.
[Researcher Sarah] Lebeer thinks the microbes may also use the hairs to bind to receptors on skin cells inside the nose, prompting the cells to close like a trap door. With fewer cells open, allergens and harmful bacteria have a harder time getting inside them.
So yes, some day, if you have a persistent sinus infection, you could be looking at a mucus transplant.
