Activation of the conserved Hippo kinases by inflammasome-triggered proteolytic cleavage controls programmed cell death in macrophages.

The mammalian Hippo kinases, MST1 and MST2, regulate organ development and suppress tumor formation by balancing cell proliferation and death. In macrophages, inflammasomes detect molecular patterns from invading pathogens or damaged host cells and trigger programmed cell death. In addition to lytic pyroptosis, the signatures associated with apoptosis are induced by inflammasome activation, but how the inflammasomes coordinate different cell death processes remains unclear.

The principle of the "growth-defense trade-off" governs how plants adjust their growth and defensive strategies in response to external factors, impacting interactions among plants, herbivorous insects, and their natural enemies. Mineral nutrients are crucial in modulating plant growth and development through their bottom-up effects. Emerging evidence has revealed complex regulatory networks that link mineral nutrients to plant defense responses, influencing the delicate balance between growth and defense against herbivores.

RNA structures that are functionally important are defined as -acting RNA elements because their functions cannot be compensated for in trans. The -acting RNA elements in the 3' UTR of coronaviruses are important for replication; however, the mechanism linking the -acting RNA elements to their replication function remains to be established. In the present study, a comparison of the biological processes of the interactome and the replication efficiency between the 3' UTR -acting RNA elements in coronaviruses, including severe acute respiratory syndrome coronavirus 2, suggests that (i) the biological processes, including translation, protein folding and protein stabilization, derived from the analysis of the -acting RNA element interactome and (ii) the architecture of the -acting RNA elements and their interactomes are highly correlated with coronavirus replication.

Unlabelled: Mutations affecting flagellin (FliC) have been shown to be hypervirulent in animal models and display increased toxin production and alterations in central metabolism. The regulation of flagellin levels in bacteria is governed by a tripartite regulatory network involving , , and , which creates a feedback system to regulate flagella production. Through genomic analysis of clade 5 strains (non-motile), we identified they have jettisoned many of the genes required for flagellum biosynthesis yet retain the major flagellin gene and regulatory gene .

The COVID-19 pandemic has revealed the need for nations to prepare more effectively for emerging infectious diseases. Preparing for these threats requires a multifaceted approach that includes assessing pathogen threat, building flexible capabilities for rapid medical countermeasure (MCM) development, and exercising, maintaining, and improving those response capabilities. The Biomedical Advanced Research and Development Authority (BARDA) promotes the advanced development of MCMs in response to natural and manmade threats.
