The hope was that the Math1 gene would be activated in the infected cells, which would then grow cilia, thus becoming hair cells. |
|
Normally, there is a thin layer of mucous and thousands of these cilia lining the insides of your breathing tubes. |
|
If the cilia are covered in tar, they can't do their job properly, and germs, chemicals and dirt can stay in your lungs and cause diseases. |

This thin mucous is swept up towards the windpipe by tiny beating hairs called cilia, where it can be coughed up or swallowed. |
|
Here, we cover progress in this field, focusing on the mechanisms of centriole and cilia assembly. |
|
Centrioles also give rise to basal bodies that control the origin of cilia and flagella in motile cells of protists. |
|

|
|
The velum and associated cilia are retracted in all the veliger larvae illustrated histologically in this report. |
|
The epithelia of ctenophores have two layers of cells rather than one, and some of the cells in the upper layer have several cilia per cell. |
|
The statocyst is protected by a transparent dome made of long, immobile cilia. |
|
This forms a mechanical system for transmitting the beat rhythm from the combs to the balancers, via water disturbances created by the cilia. |
|
Oysters are filter feeders, drawing water in over their gills through the beating of cilia. |
|
When there is underwater noise, the vibrations in the water damage the cilia hairs in the Coelenterates. |
|
Because the cilia either completely cover, as in ciliate protozoans, or are arranged in bands or clumps, the movement of each cilium must be closely coordinated with the movements of all other cilia. |
|
Each sensory cell, or hair cell, bears several small cilia, and each cilium may be stimulated by water movement or pressure from a single direction. |
|
We are also using other model organisms such as the multiciliated Paramecium to investigate the role of centriole replication components in basal body duplication and cilia assembly. |

|
The cilia help to clean out dirt and germs from your lungs. |
|
Ciliostasis, destruction of the cilia and failure of the mucociliary clearance mechanism together facilitate further colonisation, persistence, and transmission of bacteria. |
|
These nerve cells, which are known as hair cells because they have hair-like protrusions called cilia on their surfaces, fire off electrical signals when the cilia bend in response to the passage of water. |

Genome-engineered cells homozygous for these mutations have largely normal centriole numbers but show reduced CEP120 levels, compromised recruitment of distal centriole markers, and deficient cilia formation. |
