Candida albicans cell wall

The Candida albicans cell wall is a dynamic, multilayered structural organelle essential for cell survival, shape, and virulence. It comprises approximately 80-90% carbohydrate and 6-25% protein by weight. The cell wall has a bilayered architecture with an inner skeletal layer and an outer layer that determines surface properties. The inner skeletal layer consists primarily of β-1,3-glucan (47-60% of cell wall) forming a fibrillar network that is covalently cross-linked with β-1,6-glucan and chitin (0.6-9% of cell wall). These structural polysaccharides provide mechanical strength and maintain cell shape. The outer layer is enriched with mannoproteins (30-40% of cell wall), which are predominantly glycosylphosphatidylinositol-modified proteins covalently linked to the skeletal polysaccharides via β-1,6-glucan bridges. The cell wall composition and organization result from a dynamic equilibrium between synthesis and remodeling of constituent polysaccharides, adapting to environmental stresses and morphological transitions. β-1,6-glucan plays a crucial interconnecting role, linking β-1,3-glucan, chitin, and mannoproteins into an integrated structure. The cell wall is not merely a protective barrier but actively participates in adhesion, immune recognition, and pathogenicity, making it a primary target for antifungal therapeutic interventions.
