Fungal Cell Wall: Structure, Synthesis, and Assembly

Current Topics in Medical Mycology pp Cite as. The importance of cell walls must not be underestimated. Once considered to be a nonliving excretion of the cell, its importance for maintaining cell viability is now fully established. Cell walls are essential structures of most eukaryotic organisms and nearly all prokaryotes. And in a fourth one Protista cell walls are essential in some stage in the life cycle of a majority of the species. Clearly, in members and variety, the walled kingdoms dominate the biological world.

Candida albicans is one of the most important opportunistic pathogenic fungi. Weakening of the defense mechanisms of the host, and the ability of the microorganism to adapt to the environment prevailing in the host tissues, turn the fungus from a rather harmless saprophyte into an aggressive pathogen. The disease, candidiasis, ranges from light superficial infections to deep processes that endanger the life of the patient. In the establishment of the pathogenic process, the cell wall of C. It is the outer structure that protects the fungus from the host defense mechanisms and initiates the direct contact with the host cells by adhering to their surface. The wall also contains important antigens and other compounds that affect the homeostatic equilibrium of the host in favor of the parasite. In this review, we discuss our present knowledge of the structure of the cell wall of C.

It provides the cell with both structural support and protection, and also acts as a filtering mechanism. A short summary of this paper. The fungal cell wall is a dynamic structure that protects the cell from changes in osmotic pressure and other environmental stresses, while allowing the fungal cell to interact with its environment. In-plant cells, the cell wall is made up of cellulose, hemicellulose, pectin, and protein. Some features of the site may not work correctly. The wall protects the cell from desiccation and predators.

The molecular composition of the cell wall is critical for the biology and ecology of each fungal species. Fungal walls are composed of matrix components that are embedded and linked to scaffolds of fibrous load-bearing polysaccharides. Most of the major cell wall components of fungal pathogens are not represented in humans, other mammals, or plants, and therefore the immune systems of animals and plants have evolved to recognize many of the conserved elements of fungal walls. For similar reasons the enzymes that assemble fungal cell wall components are excellent targets for antifungal chemotherapies and fungicides.

The Fungal Cell Wall: Structure, Biosynthesis, and Function

Most cell walls are layered, and the innermost layer that is, the layer immediately surrounding the plasma membrane is a relatively conserved structural skeletal layer and the outer layers are more varied between species and are dynamically tailored to needs of the organism as it develops and matures and in response to interactions with the environment. Some proteins have a structural role but most contribute to the many other functions. The low concentrations of lipids and waxes found in fungal walls usually serve to control water movement, especially to prevent desiccation. These crystalline polymers are held together by spontaneous hydrogen bonding and the microfibrils have enough tensile strength to provide the wall with its main structural integrity.
