For the first time, the scientists visualised the molecular ‘nano-machinery’ that causes cilia to beat, visible as identical structures dotted every 96 nanometres along the cilia length. These ...

In healthy airways, this complex structure is tightly controlled, with molecules precisely arranged to make cilia beat in a rhythmic, wave-like motion, around a million times a day. In people with PCD ...

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 ...

The first image of the structures that power human cilia -- the tiny, hairlike projections that line our airways -- has now been produced and it could lead to much-needed treatments for people with ...
