Mitochondria in Cryptococcus: an update of mitochondrial transcriptional regulation in Cryptococcus.

Encapsulated Cryptococcus species are responsible for approximately 15% of AIDS-related mortality. Numerous intriguing investigations have demonstrated that mitochondria play a crucial role in the pathogen-host axis of microorganisms. Mitochondria are vital energy-generating organelles, but they also regulate a variety of cellular activities, such as fungal adaptability in the host and drug resistance. Mitochondria are also the source of reactive oxygen species, which serve as intracellular messengers but are harmful when produced in excess. Thus, precise and stringent regulation of mitochondrial activity, including oxidative phosphorylation and the ROS detoxification process, is essential to ensure that only the amount required to maintain basic biological activities and prevent ROS toxicity in the cell is maintained. However, the relationship between mitochondria and the pathogenicity of Cryptococcus remains poorly understood. In this review, we focus on transcription regulation and maintenance of mitochondrial function along the pathogen-host interaction axis, as well as prospective antifungal strategies that target mitochondria.
