Summary
Coordinated beating of motile cilia in multi-ciliated cells is crucial for directed fluid and cell movement. This review explores how planar cell polarity and cytoskeleton mechanisms enable this essential cilia coordination.
Area of Science:
- Cell Biology
- Biophysics
- Developmental Biology
Background:
- Multi-ciliated cells (MCCs) line organs like the oviduct, trachea, and brain ventricles.
- Motile cilia on MCCs beat unidirectionally, driving the movement of oocytes, mucus, and cerebrospinal fluid.
- Temporal coordination of neighboring cilia is essential for efficient directional transport.
Purpose of the Study:
- To review the mechanisms coordinating motile cilia beating in MCCs.
- To elucidate the roles of planar cell polarity and the cytoskeleton in cilia coordination.
- To identify future research directions in cilia coordination.
Main Methods:
- Literature review focusing on cellular mechanisms of cilia coordination.
- Analysis of studies investigating planar cell polarity in MCCs.
- Examination of cytoskeletal involvement in regulating ciliary beat patterns.
Main Results:
- Cilia coordination relies on sensing cues like organ orientation and neighboring cilia movement.
- Planar cell polarity pathways establish the directional axis for ciliary beating.
- Cytoskeletal components are critical for translating polarity cues into coordinated ciliary motion.
Conclusions:
- Coordinated ciliary beating is a complex process involving intricate cellular signaling.
- Planar cell polarity and cytoskeleton dynamics are key regulators of MCC function.
- Further research is needed to fully understand the molecular mechanisms governing cilia coordination.

3.8K
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...

01:32Cytoskeletal Coordination in Cell Migration
4.8K
A migrating cell changes its shape during the cyclic events of attachment and detachment from the substratum and repositions the cell organelles correspondingly. These complex events are orchestrated by the dynamic cytoskeletal network comprising actin filaments, intermediate filaments, and microtubules. Cytoskeletal crosstalk — the direct and indirect communication between the different components — is crucial for this coordination. Direct communication involves various linker...

01:24Microtubules in Cell Motility
3.4K
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...

01:22Microtubules in Signaling
1.8K
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...

01:16Cell Motility through Blebbing
2.0K
Blebs are a type of membrane protrusion formed by the internal hydrostatic pressure of the cytoplasm. Blebs are observed in several cell types, including fibroblasts, immune cells, and single-celled organisms like the amoeba. The primary function of blebs is cell locomotion and apoptosis, but they are also found during necrosis and cell division. The life cycle of a bleb comprises an initiation phase followed by the expansion and retraction phases.

02:13Determining the Plane of Cell Division
3.4K
Positioning the cell division plane is a critical step during development and cell differentiation, particularly during mitosis when the plane is essential for determining the size of the two daughter cells. The cell division plane is perpendicular to the plane of chromosome segregation, but different types of organisms have different cell division mechanisms to suit their morphology and function.
