Moléculas de adhesión celular: tipos y funciones
Cell adhesion molecules (CAMs) are pivotal to multicellularity and the coordinated functioning of tissues and organ systems. They enable physical ...
Estructura de las cadherinas
The cadherins were one of the first cell adhesion molecules discovered; the term “cadherins” is based on their calcium-dependent ...
Cadherinas en la organización de tejidos
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of ...
Cateninas
Catenins are characterized by multiple binding domains and dynamic structures that allow them to function as linker proteins in cell junction complexes. ...
Selectins
Cell adhesion is an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient ...
Moléculas de adhesión celular similares a las inmunoglobulinas
Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein ...
Descripción general de las uniones célula-célula
The complex three-dimensional arrangement of cells in any multicellular organism is defined and maintained by interactions of cells with each other and ...
Uniones adherentes
Strong contact points between adjacent cells anchor them to each other, forming tissues. Such anchoring junctions are of two types – adherens ...
Respuesta a la tensión en las uniones adherentes
The adherens junctions that anchor cells together are multi-protein complexes that dynamically adapt to mechanical stimuli such as tensile forces and ...
Desmosomas
The term desmosome derives from the Greek words "desmo" and "soma" meaning "adhesion bodies." This structure was first observed ...
Uniones estrechas
Tight junctions are molecular seals between cells that prevent the leaking of fluids, ions, and other small solutes across cavities and compartments in ...
Uniones de brecha
The cytoplasm of adjacent animal cells can exchange small molecules, ions, and secondary messengers via the communication channels which form the gap ...
