Objective: The fungal unfolded protein response consists of a two-component relay in which the ER-bound sensor, IreA, splices and activates the mRNA of the transcription factor, HacA. Previously, we demonstrated that is essential for virulence in a murine model of fungal keratitis (FK), suggesting the pathway could serve as a therapeutic target. Here we investigate the antifungal properties of known inhibitors of the mammalian Ire1 protein both and in a treatment model of FK.

Polymer membranes employed in gas separation play a pivotal role in advancing environmental sustainability, energy production, and gas purification technologies. Despite their significance, the current design and manufacturing of these membranes lack cradle-to-cradle approaches, contributing to plastic waste pollution. This study explores emerging solutions, including the use of biodegradable biopolymers such as polyhydroxybutyrate (PHB) and membrane recycling, with a focus on the specific impact of mechanical recycling on the performance of biodegradable gas separation membranes.

Article Synopsis
  • The study investigates the development of hypoxia in the cornea due to fungal keratitis and its impact on the virulence of fungi like Aspergillus fumigatus and Fusarium solani.
  • Researchers used C57BL/6J mice to evaluate tissue hypoxia through injections of pimonidazole, alongside genetic manipulation of A. fumigatus to understand the role of the srbA gene in virulence.
  • Findings indicate that corneal hypoxia occurs rapidly after fungal infection, and pathways like SrbA are crucial for fungi to establish infections, suggesting potential new targets for antifungal treatments.

Kin-recognition is observed across diverse species forming an important behavioral adaptation influencing organismal interactions. In many species, the molecular mechanisms involved are difficult to characterize, but in the nematode Pristionchus pacificus molecular components regulating its kin-recognition system have been identified. These determine its predatory behaviors towards other con-specifics which prevents the killing and cannibalization of kin.
