Mouse olfactory organoids revealed stem cells that preserve smell, offering clues to treat age- and disease-related smell ...

The blue staining shows the presence of SARS-CoV-2, the Covid virus, in a goblet-shaped sustentacular cell, a type of cell that supports the olfactory receptor cells in the epithelium.

Here, each developing cell’s myriad olfactory receptor genes vie with each other in a process that winnows them down, in stages, first to handful of potentials and then to a single winner.

In olfactory neurons, the DNA is arranged like a fried egg: the center of the nucleus is filled with tightly wound DNA, while key genes for smell, like those for olfactory receptors, are spread ...

Once these receptor cells are triggered, they send a signal up to a meeting point where multiple olfactory neurons converge before collectively sending a message for your brain to decipher.

Yep, vacation scents can really do that, here’s how: “When we come into contact with an odor, the olfactory receptor cells in your nose send a signal to a part of your brain called the ...

These receptors send messages to other cells in what’s called the olfactory bulb, which acts like a relay station that transmits these messages down the long nerves of the olfactory tract.

By attaching human olfactory receptors to a graphene-based sensor, researchers have created a bioelectronic nose platform for detecting a nerve agent to address biosecurity risks and support ...
