Microtubules in Signaling01:22

Microtubules in Signaling

2.3K
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

6.0K
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...

Exocytosis

10.6K
Exocytosis is a process that releases molecules outside the cell. Like other bulk transport mechanisms, exocytosis requires energy.
Exocytosis is the opposite of endocytosis, which brings molecules inside the cell. Sometimes, the released materials are signaling molecules. For example, neurons typically use exocytosis to release neurotransmitters. Cells also use exocytosis to insert proteins such as ion channels into their cell membranes, secrete proteins for use in the extracellular matrix, or...

Cell Motility through Blebbing

2.7K
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.

  • Biochemistry

Background:

  • Cilia are crucial cellular compartments involved in various cellular processes.
  • They function as sensory antennae, concentrating specific proteins for reception.
  • This specialized compartment is also involved in the regulated release of biological material.

Purpose of the Study:

  • To review emerging evidence on ciliary ectosomes.
  • To discuss their role in cellular communication and material emission.

Main Methods:

  • Literature review of studies on ciliary ectosomes.
  • Analysis of mechanisms for protein localization and vesicle release.

Main Results:

  • Cilia concentrate proteins for sensory reception and signal transduction.
  • Ciliary ectosomes are bioactive vesicles released from the cilium surface.
  • These vesicles represent a mechanism for regulated emission of biological material.
