CELL ADHESIONS Meaning and
Definition
-
Cell adhesions refer to specialized junctions between cells that enable them to interact with each other and maintain the structural integrity of tissues. These adhesions play a crucial role in various biological processes, including cell signaling, migration, and tissue formation.
Cell adhesions can be classified into different types based on their molecular composition and function. The most well-known adhesions are the adherens junctions, which are typically found in epithelial tissues. Adherens junctions are formed by the interaction of cadherin proteins on adjacent cells, providing both mechanical strength and facilitating cell-cell communication.
Another type of cell adhesion is the focal adhesion, which is mainly present in cells that interact with the extracellular matrix. Focal adhesions are formed by integrin receptors binding to various matrix proteins, such as fibronectin and collagen. These adhesions mediate cell migration, transmit mechanical forces, and regulate cell signaling pathways.
Desmosomes, also known as macula adherens, are involved in strengthening cell-cell adhesion in tissues subject to mechanical stress. Desmosomes are composed of desmogleins and desmocollins, which form strong connections between neighboring cells.
Tight junctions are another type of cell adhesion that act as barriers to control the movement of molecules between cells. These junctions prevent the leakage of substances between cells and maintain tissue integrity.
Overall, cell adhesions are fundamental for regulating cell behavior, maintaining tissue structure, and promoting proper organ development. Dysfunction or dysregulation of cell adhesions can lead to various diseases, including cancer, developmental disorders, and tissue damage. Consequently, studying cell adhesions is crucial for understanding both normal physiological processes and pathological conditions.

Etymology of CELL ADHESIONS
The word "cell adhesions" comes from the combination of two terms: "cell" and "adhesion".
The term "cell" is derived from the Latin word "cellula", meaning a small room or compartment. It was first used to describe the basic unit of living organisms by the English scientist Robert Hooke in the 17th century. Over time, "cell" has become a fundamental concept in biology, referring to the smallest structural and functional unit of an organism.
The term "adhesion" originates from the Latin word "adhaesio", meaning to stick or adhere. It is derived from the verb "adhaerere", which combines "ad", meaning "to", and "haerere", meaning "to stick". In biology, adhesion refers to the ability of molecules, cells, or tissues to stick or bind together.
