Bacterial and fungal cell wall and surface adhesins

Bacterial and fungal cell wall and surface adhesins are critical structural and functional components that enable pathogens to survive environmental stressors and colonize host tissues. The bacterial cell wall, primarily composed of peptidoglycan, provides mechanical strength and protects against osmotic lysis (StatPearls, 2023). Similarly, the fungal cell wall consists of a complex network of chitin, beta-glucans, and mannoproteins that maintain cellular integrity (Nature Reviews Microbiology, 2017). Surface adhesins are specialized molecules that mediate the attachment of these microbes to host cell receptors or abiotic surfaces, facilitating infection and the development of biofilms (Cell, 2006). Drugs targeting these structures, such as beta-lactams (e.g., Penicillins) and echinocandins (e.g., Caspofungin), are highly effective because they exploit the fundamental biochemical differences between microbial and human cells (PubChem, 2024). However, the therapeutic utility of these targets is constantly challenged by the rapid evolution of resistance mechanisms and the potential for disrupting the host's commensal flora.
