Cell-Cell Interactions
Molécules d’adhésion cellulaire - Types et fonctions
Cell adhesion molecules (CAMs) are pivotal to multicellularity and the coordinated functioning of tissues and organ systems. They enable physical ...
Structure des cadhérines
The cadherins were one of the first cell adhesion molecules discovered; the term “cadherins” is based on their calcium-dependent ...
Les cadhérines dans l’organisation tissulaire
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of ...
Catenines
Catenins are characterized by multiple binding domains and dynamic structures that allow them to function as linker proteins in cell junction complexes. ...
Sélectines
Cell adhesion is an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient ...
Molécules d’adhésion cellulaire de type immunoglobuline
Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein ...
Vue d’ensemble des jonctions cellule-cellule
The complex three-dimensional arrangement of cells in any multicellular organism is defined and maintained by interactions of cells with each other and ...
Jonctions adhérentes
Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types – adherens ...
Réponse à la tension aux jonctions adhérentes
The adherens junctions that anchor cells together are multi-protein complexes that dynamically adapt to mechanical stimuli such as tensile forces and ...
Desmosomes
The term desmosome derives from the Greek words "desmo" and "soma" meaning "adhesion bodies." This structure was first observed ...
Jonctions serrées
Tight junctions are molecular seals between cells that prevent the leaking of fluids, ions, and other small solutes across cavities and compartments in ...
Jonctions d’espace
The cytoplasm of adjacent animal cells can exchange small molecules, ions, and secondary messengers via the communication channels which form the gap ...
