Cilia and mucus are integral components of the first line of defense, particularly in the respiratory tract. They work ...

In many cells of the human body, hair-like protrusions known as cilia act as antennae, allowing cells to receive signals from ...

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 ...

Attached to nearly every human cell is an antenna-like structure known as the primary cilium, which senses the cell's environment and controls how it responds to signals from its surroundings. New ...

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 ...

Left-right asymmetry is known to be established during early embryogenesis by a small cluster of cells termed the left-right organizer. Within this organizer, motile cilia beat rapidly to create a ...

Scientists have found the most efficient length for cilia, the tiny hair-like structures designed to sweep out the body's fluids, cells and microbes to stay healthy. Human bodies have some built-in ...

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 ...

Although the human body is externally symmetric across the left-right axis, there are remarkable left-right asymmetries in the shape and positioning of most internal organs including the heart, lungs, ...

Magnetic cilia -- artificial hairs whose movement is powered by embedded magnetic particles -- have been around for a while, and are of interest for applications in soft robotics, transporting objects ...
