Candida albicans, a major human fungal pathogen, can cause a wide variety of both mucosal and systemic infections, particularly in immunocompromised individuals. Multiple lines of evidence suggest a strong association between virulence and the ability of C. albicans to undergo a reversible morphological transition from yeast to filamentous cells in response to host environmental cues. Most previous studies on mechanisms important for controlling the C. albicans morphological transition have focused on signaling pathways and sequence-specific transcription factors. However, in recent years a variety of novel mechanisms have been reported, including those involving global transcriptional regulation and translational control. A large-scale functional genomics screen has also revealed new roles in filamentation for certain key biosynthesis pathways. This review article will highlight several of these exciting recent discoveries and discuss how they are relevant to the development of novel antifungal strategies. Ultimately, components of mechanisms that control C. albicans morphogenesis and pathogenicity could potentially serve as viable antifungal targets.

在白色念珠菌中控制形态和发病机理的调控机制。

白色念珠菌是一种主要的人类真菌病原体,可引起多种粘膜和全身感染,特别是在免疫功能低下的人中。多方面的证据表明,毒力与白色念珠菌响应宿主环境线索而经历从酵母到丝状细胞的可逆形态转变的能力之间有很强的联系。以前有关控制白色念珠菌形态转变重要机制的大多数研究都集中在信号传导途径和序列特异性转录因子上。然而,近年来已经报道了多种新颖的机制,包括涉及全局转录调节和翻译控制的那些。大规模的功能基因组学筛选还揭示了某些关键生物合成途径在丝化中的新作用。这篇评论文章将重点介绍这些令人振奋的最新发现,并讨论它们与新型抗真菌策略的发展如何相关。最终,控制白色念珠菌形态发生和致病性的机制的组成部分有可能成为可行的抗真菌靶标。
