Lipidomics Approaches: Applied to the Study of Pathogenesis in Candida Species.

Abstract

High rate of reported cases of infections in humans caused by fungal pathogens pose serious concern. Potentially these commensal fungi remain harmless to the healthy individuals but can cause severe systemic infection in patients with compromised immune system. Effective drug remedies against these infections are rather limited. Moreover, frequently encountered multidrug resistance poses an additional challenge to search for alternate and novel targets. Notably, imbalances in lipid homeostasis which impact drug susceptibility of Candida albicans cells do provide clues of novel therapeutic strategies. Sphingolipids (SPHs) are unique components of Candida cells, hence are actively exploited as potential drug targets. In addition, recent research has uncovered that several SPH intermediates and of other lipids as well, govern cell signaling and virulence of C. albicans. In this chapter, we highlight the role of lipids in the physiology of Candida, particularly focusing on their roles in the development of drug resistance. Considering the importance of lipids, the article also highlights recent high-throughput analytical tools and methodologies, which are being employed in our understanding of structures, biosynthesis, and roles of lipids in fungal pathogens.
