Cilia are microtubule-based organelles projected from most eukaryotic cell surfaces performing cell motility and signaling. Several previously recognized non-ciliary proteins play crucial roles in cilium formation and function. Here, we provide additiona
How does water movement in and out of a cell differ between plants and animals? In addition to their use in motility, flagella can also be used to sense when the bacterial cell comes in contact with a surface. How are flagella used in motility? How does a bacterium move toward a nutrien...
Here we report that the majority of astrocytes across the mouse brain possess a singular primary cilium localized to the cell soma. Comparative single-cell transcriptomics reveals that primary cilia mediate canonical SHH signaling to modulate astrocyte subtype-specific core features in synaptic regulation...
How do molecules move in and out of cells? In addition to their use in motility, flagella can also be used to sense when the bacterial cell comes in contact with a surface. How are flagella used in motility? How does a bacterium move toward a nutrient source using flagella? Select the ...
A bacterial cell may possess a single flagellum or a tuft of flagella at one or both poles and the flagella may be distributed more or less randomly over the cell surface. The occurrence of fibrils, possibly tubular but this has yet to be conclusively demonstrated, in many motile cellular ...
Originally, the term cilia was used when a cell had a large number of ciliary structures that were all relatively short, such as in Paramecium, and the term flagella was applied to the single long structure found on cells such as sperm cells, even though the underlying ultrastructure is the...
Motile cilia are found on the cell surface in larger numbers. These are also found in the respiratory epithelium of the human respiratory tract and help by clearing the mucus or the dust particles out of the lungs. 2.Non-motile Cilia ...
The SARS-CoV-2 Spike protein mediates docking of the virus onto cells prior to viral invasion. Several cellular receptors facilitate SARS-CoV-2 Spike docking at the cell surface, of which ACE2 plays a key role in many cell types. The intermediate filamen
