Pathogenic fungi represent a growing concern for human health, necessitating a deeper understanding of their molecular mechanisms of virulence to formulate effective antifungal strategies. Recent research has increasingly highlighted the role of phospholipid components in fungal cell membranes, which are not only vital for maintaining cellular integrity but also significantly influence fungal pathogenicity. This review focuses on the impact of membrane phospholipid composition on fungal growth, morphogenesis, stress responses, and interactions with host cells. To be specific, membrane phospholipid composition critically influences fungal virulence by modulating growth dynamics and morphogenesis, such as the transition from yeast to hyphal forms, which enhances tissue invasion. Additionally, phospholipids mediate stress adaptation, enabling fungi to withstand host-derived oxidative and osmotic stresses, crucial for survival within hostile host environments. Phospholipid asymmetry also impacts interactions with host cells, including adhesion, phagocytosis evasion, and the secretion of virulence factors like hydrolytic enzymes. These adaptations collectively enhance fungal pathogenicity by promoting colonization, immune evasion, and damage to host tissues, directly linking membrane architecture to infection outcomes. By elucidating the molecular mechanisms involved, we aim to underscore the potential of targeting phospholipid metabolic pathways as a promising avenue for antifungal therapy. A comprehensive understanding of how membrane phospholipid composition regulates the virulence of pathogenic fungi can provide valuable insights for developing novel antifungal strategies.
