Cilia and flagella are evolutionarily conserved, microtubule-based, hair-like organelles that protrude from the cell surface. They are the fundamental units of motion in cellular biology, and also ...

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 ...

In many cells of the human body, hair-like protrusions known as cilia act as antennae, allowing cells to receive signals from their environment and other cells. As cells grow and divide, each cilium ...

New research has unraveled the mystery of how microscopic cilia coordinate to move and propel marine creatures through water. Cilia are tiny, hair-like protrusions found in many organisms, including ...

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 ...

Many cells in our body have a single primary cilium, a micrometer-long, hair-like organelle protruding from the cell surface that transmits cellular signals. Cilia are important for regulating ...

Now, in a recently published Journal of Cell Biology paper, scientists used a newer electron microscopy technique, called volume electron microscopy (vEM), to examine how primary cilia on developing ...

In recent years, researchers have been learning more about why cellular antennas called cilia are so important. Cilia can act as sensors of the cell's environment and can send and receive signals.

You might know that our lungs are lined with hair-like projections called motile cilia. These are tiny microtubule structures that appear on the surface of some cells or tissues. They can be found ...

One tiny flick of a microscopic cellular hair, known as a cilium, can’t do much on its own. But together, these structures routinely pull off biological marvels within the body. Cilia remove inhaled ...

Flagella are composed of over 20 unique proteins and represent a complex set of molecular machinery, working in unison to provide motility to many Gram-negative and positive species of bacteria, as ...
