Exposure to ultrafine particles from traffic alters the expression of many genes in human olfactory mucosa cells, a new study shows. The study is the first to combine an analysis of emissions from ...

It is now widely known that COVID-19 is associated with the transient or long-term loss of olfaction (the sense of smell) but the mechanisms remain obscure. An unresolved question is whether the ...

An illustration of the olfactory bulb and epithelium. Top right: A pericyte (light orange) wraps around a blood vessel (red). Bottom right: Olfactory sensory neurons (light red, orange) surrounded by ...

While smell plays a considerable role in the social interactions of humans - for instance, signaling fear or generating closeness - for ants, it is vitally important. Researchers from New York ...

The signaling mechanisms underlying the transition from stem cells to olfactory neurons has been described. Cellular differentiation of stem cells into specialized cells requires many steps, including ...

Implanting olfactory ensheathing glial cells into the spinal cords of paralyzed adult rats recently has been shown to promote neuronal cell repair and restore function. After transplantation, the rats ...

Researchers have developed and characterized a new cell model for Alzheimer's disease that has wide utility for research and could prove useful in early diagnosis and testing of new therapies.

A research team led by scientists at Columbia’s Zuckerman Institute used techniques including single cell genomics, to describe a previously undetected RNA-mediated mechanism in mice that could ...

In a compost heap, the nematode Caenorhabditis elegans finds a richly laid table: at a length of just one millimeter, the worm feeds on bacteria that decompose organic material. It is essential that ...
