Adherens Junctions01:24

Adherens Junctions

4.8K
Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types –  adherens junctions and desmosomes. Adherens junctions are abundant in tissues such as  epithelium and endothelium, forming a continuous zone of adhesion called the adhesion belt. In other tissues, such as  heart muscle, they appear as clusters, linking the cells to produce coordinated heart muscle contraction.

Surface Appendages of Archaea01:23

Surface Appendages of Archaea

27
Archaeal surface appendages are highly specialized structures essential for environmental adaptation, encompassing roles in adhesion, biofilm formation, and motility. Among these appendages, pili and archaella stand out for their distinct morphologies and functionalities, enabling archaea to thrive in diverse and often extreme environments.Pili: Adhesion and Biofilm FormationPili are filamentous structures assembled from pilin protein subunits, primarily contributing to adhesion and biofilm...

Intracellular Signaling Affects Focal Adhesions01:17

Intracellular Signaling Affects Focal Adhesions

2.7K
Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

Fimbriae, Pili, and Axial Filaments01:28

Fimbriae, Pili, and Axial Filaments

29
Fimbriae and pili are specialized bacterial surface structures that play pivotal roles in adhesion, genetic exchange, and motility. Composed primarily of pilin protein, these hairlike appendages are crucial for bacterial survival and pathogenicity in various environments.Fimbriae: Adhesion and PathogenicityFimbriae are fine, filamentous structures measuring 2–10 nanometers in diameter and are densely distributed on the bacterial cell surface. They facilitate bacterial adhesion to abiotic...

Structure of Cadherins01:25

Structure of Cadherins

3.4K
The cadherins were one of the first cell adhesion molecules discovered; the term “cadherins”   is based on their calcium-dependent adhering properties. The first cadherins discovered on the epithelial, neuronal, and placental cells were named E-cadherin, P-cadherin, and N-cadherin, respectively. These classical cadherins share sequence and structural similarities. Other cadherins, including those involved in cell signaling, are grouped into non-classical cadherins. This...

Area of Science:

  • Mycology
  • Infectious Diseases
  • Microbiology

Background:

  • Candida auris is a rapidly emerging fungal pathogen causing widespread invasive infections.
  • Understanding the mechanisms of C. auris colonization and virulence is critical for controlling outbreaks.

Purpose of the Study:

  • To identify novel factors mediating Candida auris colonization.
  • To investigate the role of identified factors in fungal adhesion and pathogenicity.

Main Methods:

  • Utilized genetic screening and molecular biology techniques.
  • Assessed fungal colonization on abiotic surfaces, host skin models, and in vivo virulence models.

Main Results:

  • A novel surface colonization factor (SCF1) was identified.
  • The conserved adhesin Iff4109 was shown to mediate C. auris colonization.
  • SCF1 and Iff4109 facilitate adhesion to abiotic surfaces and host skin.
  • These factors contribute to the overall virulence of C. auris in vivo.

Conclusions:

  • SCF1 and Iff4109 are key mediators of Candida auris colonization and virulence.
  • Targeting these factors may offer new strategies for preventing and treating C. auris infections.
