These prophages confer advantages to their bacterial host, yet also pose a lethal threat as they can reactivate and enter a lytic cycle. DNA damage of the bacterial host is a common trigger of prophage lytic cycles. Because DNA damage is frequently experienced by bacterial pathogens exposed to host immune defenses, prophage activation may be common during infection. Investigating the consequences of prophage induction in <em>Salmonella</em>, we discover a prophage competition element in the Gifsy-1 prophage that we name ribonuclease effector module with ATPase, inhibitor, and nuclease (RemAIN) because it blocks the lytic cycles and release of viral particles of co-resident prophages. Intramacrophage <em>Salmonella</em> persisters, a subpopulation that incurs DNA damage, experience prophage reactivation and subsequent RemAIN activation, which influences <em>Salmonella</em> persisters and macrophage response to infection. Our findings reveal a multi-layered host-pathogen arms race in which prophage-prophage competition influences bacterial persistence and the mammalian immune response.","PeriodicalId":9693,"journal":{"name":"Cell host & microbe","volume":null,"pages":null},"PeriodicalIF":30.3,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142594575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We followed patients with unresectable melanoma from baseline and during anti-PD-1 therapy, collecting fecal and blood samples that were surveyed for changes in the gut microbiota and immune markers. Varying patient responses were linked to different gut microbiota dynamics during ICI treatment. We select complete responders by their stable microbiota functions and validate them using multiple external cohorts and experimentally. We identify major histocompatibility complex class I (MHC class I)-restricted peptides derived from flagellin-related genes of <em>Lachnospiraceae</em> (<em>FLach</em>) as structural homologs of tumor-associated antigens, detect <em>FLach</em>-reactive CD8<sup>+</sup> T cells in complete responders before ICI therapy, and demonstrate that <em>FLach</em> peptides improve antitumor immunity.

An evolutionary analysis revealed that <em>Mtb</em> genomes are enriched in partially deleterious mutations. Genome-wide association studies identified small and large deletions in <em>eccB2</em> significantly associated with patient prognosis. Additionally, we unveil significant associations with antibiotic resistance in 23 non-canonical genes. Among these, large indels are primarily found in genetic regions of <em>Rv1216c</em>, <em>Rv1217c</em>, <em>fadD11</em>, and <em>ctpD</em>.

We established a prospective pediatric cohort to characterize the function of fecal microbiota and metabolite changes of treatment-naive CD patients in response to EEN (German Clinical Trials DRKS00013306). Integrated multi-omics analysis identified network clusters from individually variable microbiome profiles, with <em>Lachnospiraceae</em> and medium-chain fatty acids as protective features. Bioorthogonal non-canonical amino acid tagging selectively identified bacterial species in response to medium-chain fatty acids. Metagenomic analysis identified high strain-level dynamics in response to EEN. Functional changes in diet-exposed fecal microbiota were further validated using gut chemostat cultures and microbiota transfer into germ-free <em>Il10</em>-deficient mice. Dietary model conditions induced individual patient-specific strain signatures to prevent or cause inflammatory bowel disease (IBD)-like inflammation in gnotobiotic mice. Hence, we provide evidence that EEN therapy operates through explicit functional changes of temporally and individually variable microbiome profiles.","PeriodicalId":9693,"journal":{"name":"Cell host & microbe","volume":null,"pages":null},"PeriodicalIF":30.3,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142489634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Apart from <em>Lactobacillus iners</em>, the presence of <em>Lactobacillus</em> species is associated with reduced vaginal inflammation and reduced levels of pro-inflammatory cytokines. Loss of <em>Lactobacillus</em>-dominance is associated with inflammatory conditions, such as bacterial vaginosis (BV). We have identified that <em>Lactobacillus crispatus</em>, a key vaginal bacterial species, produces a family of β-carboline compounds with anti-inflammatory activity. These compounds suppress nuclear factor κB (NF-κB) and interferon (IFN) signaling downstream of multiple pattern recognition receptors in primary human cells and significantly dampen type I IFN receptor (IFNAR) activation in monocytes. Topical application of an anti-inflammatory β-carboline compound, perlolyrine, was sufficient to significantly reduce vaginal inflammation in a mouse model of genital herpes infection. These compounds are enriched in cervicovaginal lavage (CVL) of healthy people compared with people with BV. This study identifies a family of compounds by which vaginal lactobacilli mediate host immune homeostasis and highlights a potential therapeutic avenue for vaginal inflammation.","PeriodicalId":9693,"journal":{"name":"Cell host & microbe","volume":null,"pages":null},"PeriodicalIF":30.3,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142444187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pollen is a source of PUFAs for honeybees, and disruptions in dietary PUFAs reduce the cognitive performance of honeybees. We reveal that gut bacteria of honeybees contribute to fatty acid metabolism, impacting reward learning. Gut bacteria possess Δ-6 desaturases that mediate fatty acid elongation and compensate for the absence of honeybee factors required for fatty acid metabolism. Colonization with <em>Gilliamella apicola</em>, but not a mutant lacking the Δ-6 desaturase FADS2, increases the production of anandamide (AEA), a ligand of the endocannabinoid system, and alters learning and memory. AEA activates the Hymenoptera-specific transient receptor AmHsTRPA in astrocytes, which induces Ca<sup>2+</sup> influx and regulates glutamate re-uptake of glial cells to enhance reward learning. These findings illuminate the roles of gut symbionts in host fatty acid metabolism and the impacts of endocannabinoid signaling on the reward system of social insects.","PeriodicalId":9693,"journal":{"name":"Cell host & microbe","volume":null,"pages":null},"PeriodicalIF":30.3,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142439715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
