AI Article Synopsis

  • In a mouse model of malaria, infection triggers significant changes in the body’s metabolism and immune response during both sickness and recovery.* -
  • The study found that metabolite increases activate the aryl hydrocarbon receptor (AHR), which plays a key role in modulating the immune response.* -
  • Mice with higher AHR activity showed greater susceptibility to malaria and suffered from severe health issues, indicating that AHR helps protect against tissue damage during infection.*

Article Abstract

Systemic metabolic reprogramming induced by infection exerts profound, pathogen-specific effects on infection outcome. Here, we detail the host immune and metabolic response during sickness and recovery in a mouse model of malaria. We describe extensive alterations in metabolism during acute infection, and identify increases in host-derived metabolites that signal through the aryl hydrocarbon receptor (AHR), a transcription factor with immunomodulatory functions. We find that mice are more susceptible to malaria and develop high plasma heme and acute kidney injury. This phenotype is dependent on AHR in -expressing radioresistant cells. Our findings identify a role for AHR in limiting tissue damage during malaria. Furthermore, this work demonstrates the critical role of host metabolism in surviving infection.

Polycystic ovary syndrome (PCOS) affects 6%-10% of women of reproductive age and is known to be associated with disruptions in the gut bacteria. However, the role of the gut mycobiota in PCOS pathology remains unclear. Using culture-dependent and internal transcribed spacer 2 (ITS2)-sequencing methods, we discovered an enrichment of the gut-colonizable fungus Aspergillus tubingensis in 226 individuals, with or without PCOS, from 3 different geographical areas within China.

Sepsis is a major cause of morbidity and mortality, but our understanding of the mechanisms underlying survival or susceptibility is limited. Here, as pathogens often subvert host defence mechanisms, we hypothesized that this might influence the outcome of sepsis. We used microbiota analysis, faecal microbiota transplantation, antibiotic treatment and caecal metabolite analysis to show that gut-microbiota-derived tryptophan metabolites including indoles increased host survival in a mouse model of Serratia marcescens sepsis.

Excess dietary salt and salt-sensitivity contribute to cardiovascular disease. Distinct T cell phenotypic responses to high salt and hypertension as well as influences from environmental cues are not well understood. The aryl hydrocarbon receptor (AhR) is activated by dietary ligands, promoting T cell and systemic homeostasis.

Introduction: Tapinarof is a topical aryl hydrocarbon receptor (AhR) agonist in development for the treatment of atopic dermatitis (AD). In two phase 3 trials (ADORING 1 and 2), tapinarof cream 1% once daily (QD) demonstrated significant efficacy and was well tolerated in patients down to age 2 years with AD. Here, we evaluate patient-reported outcomes (PROs), including family impact, with tapinarof in ADORING 1 and 2.
