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 ...

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 ...

Existence of cellular structures with specific size raises a fundamental question in biology: How do cells measure length? One conceptual answer to this question is by a molecular ruler, but examples ...

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 ...

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 ...

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 ...

One essential component of each eukaryotic cell is the cytoskeleton. Microtubules, tiny tubes consisting of a protein called tubulin, are part of this skeleton of cells. Cilia and flagella, which are ...

Although the cilium has been known to scientists for more than 100 years, it is only recently that it has been acknowledged to play important roles in physiology. Virtually every cell has a primary ...

The rhythmic motions of hair-like cilia move liquids around cells or propel the cells themselves. In nature, cilia flap independently, and mimicking these movements with artificial materials requires ...

Loss of primary cilia results in the downregulation of PD-L1 expression, which contributes to unrestrained local T cell proliferation and activation. Ciliopathies are multisystem disorders ...

Primary cilia are microscopic sensory antennae that transmit extracellular signals into intracellular biochemical responses. Growing evidence indicates that primary cilia are implicated in brain ...
