Treatment of invasive aspergillosis is currently limited to only three classes of antifungals, the use of which is hampered by toxicity and rising antifungal resistance rates. The front-line therapeutic class, the triazoles, functions through the inhibition of ergosterol biosynthesis, and the majority of clinical triazole resistance is caused by target gene mutations impacting the sterol demethylase Cyp51. In this study, we differentiate the biological roles of three putative\n                        <jats:italic toggle=\"yes\">A. fumigatus<\/jats:italic>\n                        lanosterol synthase paralogs as enzymes functioning upstream of the triazole target. We provide strong genetic and pharmacological evidence that inhibition of this upstream enzymatic step in the ergosterol biosynthetic pathway is synergistic with triazoles and can resensitize resistant clinical isolates. The development of lanosterol synthase inhibitors with fungus-specific activity is expected to provide new stand-alone and\/or combination therapies to improve outcomes of invasive aspergillosis.\n
