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

5.8K
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...

Cystic Fibrosis: Pathogenesis

1.1K
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Microtubules in Cell Motility

5.1K
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...

Purpose of the Study:

  • To review the genetics of BBS.
  • To explore the function of BBS proteins in cilia and potential extra-ciliary roles.
  • To highlight BBS's contribution to understanding ciliopathies.

Main Methods:

  • Genetic analysis of BBS patients.
  • Functional characterization of BBS proteins.
  • Review of existing literature on BBS and cilia biology.

Main Results:

  • BBS genetics involves complex mutational burdens.
  • BBS proteins are crucial for primary cilium function.
  • Extra-ciliary roles of BBS proteins may contribute to BBS etiology.

Conclusions:

  • The study of BBS has significantly advanced the understanding of primary cilia.
  • Knowledge of cilia biology informs the cellular basis of BBS clinical manifestations.
  • BBS research provides insights into the broader group of ciliopathies.
