The glycocalyx functions include: (1) limiting the access of certain molecules to the EC membrane, (2) dissipating fluid shear stress at a distance from the membrane, and (3) potentially transmitting the mechanical forces into the cell via GAG and core protein components.
Included in the glycocalyx are cell-adhesion molecules that enable cells to adhere to each other and guide the movement of cells during embryonic development. The glycocalyx plays a major role in regulation of endothelial vascular tissue, including the modulation of red blood cell volume in capillaries.
Whats is the overall function of a glycocalyx? Protects the cell inside of it and aids in adherence to it’s environment (important in it’s effort to cause disease).
On bacterial cells, the glycocalyx provides a protective coat from host factors. The possession of a glycocalyx on bacteria is associated with the ability of the bacteria to establish an infection.
The glycocalyx helps the stomach break down food. The glycocalyx protects the cells of the small intestine from sheer stress and helps break down food.
The glycocalyx is the carbohydrate-rich layer that surrounds the cell membranes of eukaryotic cells, including bacteria. It is made up of various polysaccharides and glycoproteins that are firmly attached to the cell wall. It has three main functions: to protect the cell from environmental elements, to promote adhesion between cells, and to promote bacterial cell-to-cell contact. Glycocalyx may be in the form of a slime layer or an irregular capsule, depending on its thickness.
The glycocalyx has many functions. It protects bacteria from drying, traps nutrients, and protects them from phagocytic engulfment. It also allows bacteria to adhere to inert surfaces and colonize. It also helps bacteria resist flushing. Phosphagocytosis is a complex process. A bacterium has to attach itself to the cytoplasmic membrane before it can be inhaled. This attachment may be unenhanced or enhanced depending on its role in the process.
The glycocalyx layer is composed of sugar chains that are attached to transmembrane proteins at the endothelial cell surface. A model of the glycocalyx layer is extremely difficult to create. Because the sugar chains are highly heterogeneous in structure, crystallization and NMR analysis are not helpful. Consequently, we can only make low-resolution images of the glycocalyx. Moreover, glycocalyx models have only considered the negative charge of each sugar chain and have ignored the interactions among biomolecular components.
The glycocalyx has important roles in the healing process of septic shock and sepsis. Its degeneration can lead to altered vascular permeability, tissue edema, and leukocyte adhesion. Therefore, restoration of the glycocalyx may be a therapeutic target. This is a fascinating concept that needs to be explored further. There are many clinical uses for the glycocalyx and we are only scratching the surface.
