Abstract

ABSTRACTEicosanoids are bioactive lipid mediators generated in almost all mammalian cells from the oxidation of arachidonic acid and other related twenty-carbon polyunsaturated fatty acids (PUFA). Eicosanoids regulate various physiological functions, including cellular homoeostasis and modulation of inflammatory responses in mammals. The mode of action of these lipid mediators depend on their binding to different G-protein coupled receptors. The three main enzymatic pathways associated with their production are the COX pathway, LOX pathway and cytochrome P450 pathway. Interestingly, investigations have also revealed that several human pathogenic fungi are capable of producing these bioactive lipid mediators; however, the exact biosynthetic pathways and their function in pathogenicity are not yet extensively characterized. The aim of the current review is to summarize the recent discoveries pertaining to eicosanoid production by human pathogenic yeasts with a special focus on the opportunistic human fungal pathogen Candida parapsilosis.

Highlights

  • Oxylipins are oxidized lipid molecules generated from the oxidation of polyunsaturated fatty acids [1]

  • Based upon the currently available studies, in this review, we provide an up-to-date and brief summary of eicosanoid production in pathogenic yeasts as well as their role in pathogenesis development, with a special focus on an emerging fungal pathogenic species, Candida parapsilosis

  • C. neoformans deletion mutants of phospholipase B (PLB) or laccase (LAC) enzymes are less virulent in mice compared to the wild type strain, indicating the role of these genes in pathogenesis [33,35], albeit their functions impact more than eicosanoid biology

Summary

Introduction

Oxylipins are oxidized lipid molecules generated from the oxidation of polyunsaturated fatty acids [1]. KEYWORDS Candida parapsilosis; pathogenic yeast; fungal eicosanoids; virulence Besides HETE and PGE2, these species are able to produce PGD2 and PGF2α as well as leukotrienes (LTB4, cysteinyl leukotrienes) from exogenous arachidonic acid [11].
