Primary cilia are sensory organelles present on the cell surface; however, their physical structure has not been defined due to technical reasons. A new PNAS study examined primary cilia in human ...

Cilia, the little "hairs" attached to almost all cells of the human body, play a role in various cellular functions and cause diseases called ciliopathies when they are defective. Researchers from the ...

Cilia are ubiquitous on cells, playing a variety of roles, Dr. Nicastro explained. While non-motile cilia serve as sensors for chemical and mechanical signals, motile cilia rhythmically beat to propel ...

These whip-like organelles help protect humans from disorders like hydrocephaly and epilepsy, but scientists are puzzled by their structure. Through an NIH-funded research project, Brian Bayless hopes ...

Tiny, solitary spikes that stick out of nearly every cell in the body play a central role in a type of skin cancer, new research has found. The discovery in mice shows that the microscopic structures ...

Paramecium and certain other microbes move through liquid by whipping back and forth hairlike appendages known as cilia. Scientists have now developed a new type of synthetic cilia, which could find ...

Tiny hairlike structures on pancreatic cells have long been considered static sensors. Now, researchers say they move and help regulate insulin secretion. Shafaq Zia is a freelance science journalist ...

A coronavirus infection can mow down the forests of hairlike cilia that coat our airways, destroying a crucial barrier to keeping the virus from lodging deep in the lungs. Normally, those cilia move ...

Beyond the diffraction limit (a) Pre-expansion image of human kidney tissue using a ×60 objective lens and processed with super-resolution optical fluctuation imaging (scale bar: 5 µm). (b) The same ...
