Fungal pathogen cell wall component

Fungal pathogen cell wall components form a multilayered, dynamic exoskeleton surrounding fungal cells. The main polymers are β-1,3-glucan, chitin, and mannan, often cross-linked and attached to glycoproteins. The structural scaffold provides cell shape, integrity, and protection against environmental stresses and immune attack. Fungal cell wall elements are absent in human cells, making them attractive antifungal drug targets. Key enzymes involved in biosynthesis—such as β-D-glucan synthase and chitin synthase—are therapeutic targets. Clinical antifungals like echinocandins disrupt cell wall architecture, leading to cell lysis and death. Fungi may develop resistance through cell wall remodeling (e.g., increased chitin), underlining the importance of ongoing research into cell wall molecular biology, adaptations, and new drug targets.
