Mechanisms of ciliary movement: contributions from electron microscopy
1Department of Anatomy and Structural Biology, Albert Einstein College of Medicine, Bronx, NY 10461.
Summary
Electron microscopy revealed universal ciliary axonemal structure and the sliding microtubule model for ciliary motility. These studies unexpectedly highlighted cilia
Area of Science:
- Cell Biology
- Biophysics
Background:
- Ciliary motility is crucial for cellular function.
- Understanding the mechanisms of ciliary movement is a long-standing biological challenge.
Purpose of the Study:
- To review the significant contributions of electron microscopy to understanding ciliary motility.
- To highlight the development of key models explaining ciliary movement.
Main Methods:
- Review of electron microscopy studies on ciliary structure and function.
- Analysis of the development of the sliding microtubule model.
- Examination of the switch point hypothesis for bending dynamics.
Main Results:
- Electron microscopy demonstrated the conserved axonemal structure across diverse cilia.
- The sliding microtubule model was established as a fundamental mechanism for ciliary motility.
- The switch point hypothesis provided an explanation for the conversion of sliding to bending.
Conclusions:
- Electron microscopy has been instrumental in elucidating ciliary motility mechanisms.
- These investigations unexpectedly revealed the critical role of cilia in human health.
- Further research into ciliary function is warranted.

The Movement of Organelles and Vesicles
In eukaryotic cells, cytoskeletal filaments such as actin, microtubules, and intermediate filaments form a mesh-like cytoskeletal network. These filaments serve as tracks for transporting cellular cargo. Specialized motor proteins use the chemical energy stored in adenosine triphosphate (ATP) for this transport. During interphase, microtubules are polarized, with the plus-end towards the cell periphery and the minus-end towards the cell center. Two microtubule-associated motor proteins,...
Microtubules in Cell Motility
Microtubules are thick hollow cylindrical proteins that help form the cytoskeleton. Microtubules have varied roles in the cell. These filaments help form cellular appendages like cilia and flagella, which are responsible for locomotion. The cilia arise from basal bodies, separated from the main body by a membrane-like structure forming the transition zone. This zone is the gate for the entry of lipids and proteins, creating a unique composition of lipids and proteins in the ciliary membrane and...
Microtubules in Signaling
The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...
Mechanism of Ciliary Motion
The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...
