Summary
Primary cilia are vital microtubule organelles. Aberrant ciliogenesis causes ciliopathies, including retinal dysfunction, highlighting the need for new therapies targeting key protein networks.
Area of Science:
- Cell Biology
- Genetics
- Ophthalmology
Background:
- Primary cilia are ubiquitous microtubule-based organelles crucial for sensing the environment and modulating signaling pathways.
- Defects in ciliogenesis or ciliary transport result in ciliopathies, a group of disorders with diverse phenotypes, including sensory defects and multi-organ pathologies.
- Photoreceptors in the retina possess a specialized cilium (outer segment) essential for light detection; retinal dysfunction is a common feature of ciliopathies.
Purpose of the Study:
- To review primary cilia biogenesis and ciliopathies, with a specific focus on retinal manifestations.
- To elucidate the role of the CP110-CEP290-CC2D2A protein network in cilia formation and function.
- To explore how emerging technologies can enhance understanding of cilia biology and inform therapeutic strategies for retinal ciliopathies.
Main Methods:
- This is a review article, synthesizing existing research on primary cilia, ciliogenesis, and ciliopathies.
- Focuses on the molecular mechanisms involving the CP110-CEP290-CC2D2A network.
- Discusses the application of recent technological advancements in studying cilia biology.
Main Results:
- Primary cilia biogenesis is a complex process involving numerous components.
- Ciliopathies, particularly those affecting the retina, are linked to defects in cilia structure and function.
- The CP110-CEP290-CC2D2A network plays a critical role in ciliogenesis.
Conclusions:
- Understanding primary cilia biogenesis and the CP110-CEP290-CC2D2A network is crucial for deciphering ciliopathies.
- Retinal ciliopathies represent a significant clinical challenge requiring further investigation.
- New technologies and therapeutic approaches hold promise for treating retinal ciliopathies.

2.0K
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...

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...

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
