Mechanism of Ciliary Motion01:05

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...

Accessory Structures of the Eye01:17

Accessory Structures of the Eye

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
Anatomy of the Eyeball01:20

Anatomy of the Eyeball

The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...
Determining the Plane of Cell Division02:13

Determining the Plane of Cell Division

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. 
Animal cells
In animal cells, the cleavage furrow forms along the plane of cell division starting...
Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Area of Science:

  • Cell Biology
  • Molecular Biology
  • Structural Biology

Background:

  • Cilia are crucial for cellular signaling and development.
  • Precise control over ciliary composition is essential for their function.
  • Mechanisms for ciliary compartmentalization remain incompletely understood.

Purpose of the Study:

  • To identify and characterize the structure responsible for ciliary base compartmentalization.
  • To elucidate the components and function of this newly described system.

Main Methods:

  • Structural analysis of the ciliary base.
  • Proteomics analysis of the periciliary membrane.
  • High-resolution imaging techniques.

Main Results:

  • A novel structure, the ciliary partitioning system (CPS), was identified at the ciliary base.
  • The CPS comprises a ciliary pore complex (CPC) and a membrane diffusion barrier (ciliary pocket).
  • Proteomics revealed vesicle trafficking involvement in the ciliary pocket, indicating active membrane transport.

Conclusions:

  • The CPS acts as a gatekeeper, controlling molecular entry and exit from cilia.
  • This system is vital for maintaining ciliary function and signaling pathway integrity.
  • The ciliary partitioning system (CPS) defines the ciliary boundary and regulates intraflagellar transport.
