However, many pathogenic fungi harbor bacterial associates that influence their ecology, persistence and virulence. The pathobiome concept addressed this limitation by framing disease as an outcome of multi-kingdom interactions. Yet most pathobiome studies rely on correlative analyses of microbial abundances with pathogens, lacking spatial resolution to identify which microorganisms physically interact with pathogenic structures. Conversely, the hyphosphere provides micrometer-scale spatial resolution but has been investigated predominantly in non-pathogenic fungi. Here, we propose the pathomycosphere as a spatially defined and experimentally tractable subset of the pathobiome: a hypha-associated microbial assemblage in which physical association with the pathogenic member, prolonged or transient has a consequence for the pathogen's biology, with pathogenicity residing in the fungus, an associated microorganism or their interaction. This framework bridges the pathobiome and hyphosphere concepts by anchoring disease-associated microbial interactions to hyphal interface, where mechanistic investigation becomes feasible. Pathomycosphere provides operational tractability to explore microbial partnerships contributing to pathogenesis, and positions fungal-associated bacterial consortia as important components of pathogen biology with relevance to disease ecology beyond agricultural systems.","PeriodicalId":12201,"journal":{"name":"FEMS microbiology reviews","volume":" ","pages":""},"PeriodicalIF":16.9,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149237426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this review, we investigate the architecture and regulatory functions of c-di-GMP signaling in classical Bordetella species, including B. bronchiseptica, B. parapertussis and B. pertussis. We examine how the c-di-GMP signaling pathway interacts with the BvgAS two-component system and other signaling pathways to coordinate virulence gene expression and surface-associated behaviors in these respiratory pathogens. In particular, we highlight the functions of characterized diguanylate cyclases (DGCs), phosphodiesterases (PDEs) and dual-domain proteins, focusing on regulatory modules such as the BdcA-DdpA scaffold complex, the oxygen-sensing DGC BpeGReg and the LapD-LapG proteolytic switch that controls BrtA adhesin. We also propose a model for the function of BvgR, a PDE-like protein lacking catalytic residues, and discuss how c-di-GMP suppresses the type III secretion system. Importantly, we highlight the diversity of the c-di-GMP network in classical Bordetella species, likely reflecting their evolutionary specialization. To conclude, we outline important open questions and suggest future research directions, including the identification of sensory ligands and c-di-GMP effectors. Overall, our review illustrates the importance of c-di-GMP as a critical, but still incompletely understood, regulatory hub in Bordetella pathogenesis.","PeriodicalId":12201,"journal":{"name":"FEMS microbiology reviews","volume":" ","pages":""},"PeriodicalIF":12.3,"publicationDate":"2026-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12805831/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145833328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a sialic acid-binding immunoglobulin-like lectin (Siglec), CD169 recognizes sialylated gangliosides and glycoconjugates present on surface of several viral envelopes, including HIV-1, SARS-CoV-2, and Ebola virus as well as sialylated bacterial capsules such as those of Neisseria meningitidis and Campylobacter jejuni. Moreover, different viruses were shown to be captured by CD169+ cells which could play distinctive role during infections: they could enhance efficient immune responses, but also facilitate pathogen dissemination through viral capture and transfer to permissive cells. This last mechanism has been well documented for HIV-1, where CD169 mediates viral trans-infection of CD4⁺ T-cells. CD169 expression is rapidly induced by type-I interferons during acute viral infections and has emerged as a valuable biomarker to distinguish viral from bacterial infection, particularly for COVID-19 and influenza. Detectable by flow cytometry, CD169 represents a solid biomarker in clinical settings and possible target in the development of novel prophylactic and therapeutic strategies. Its dual role, protective in host defence yet exploitable by certain pathogens, highlights the need for careful consideration in future therapeutic approaches.","PeriodicalId":12201,"journal":{"name":"FEMS microbiology reviews","volume":" ","pages":""},"PeriodicalIF":16.9,"publicationDate":"2026-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13070564/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147485233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most predator-prey studies use simplified pairwise interactions, constraining our ability to identify general principles. Here, predator-prey choices are examined across scales and levels of environmental complexity. We review current knowledge and emphasize the diversity and complexity of predator-prey systems, point to challenges in integrating them, and propose a framework that could benefit predictive modeling for ecosystem functioning and resilience. To do so, we compare the tools, mechanisms, and strategies deployed by micro- and macro- predators and prey defenses to show that commonalities become identifiable, and suggest structural and functional links between micro- and macro-scales. This provides arguments for both descriptive, and mathematical models. We propose that the use of microbial predators like the Bdellovibrio and like organisms can greatly advance the integration of experimental and mathematical modeling research, as they can provide robust empirical observations of predator-prey interactions tested under multiple conditions and levels of complexity. This facilitates model development, in turn leading to new hypotheses. We conclude by showing examples of current developments, that predator-prey interaction-based knowledge has the potential to provide novel medical tools and to improve environmental and agricultural management.","PeriodicalId":12201,"journal":{"name":"FEMS microbiology reviews","volume":" ","pages":""},"PeriodicalIF":16.9,"publicationDate":"2026-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12927660/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146164683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Being vastly underrepresented in laboratory-based studies, we also critically lack knowledge and approaches to improve their resilience to emerging threats from climate change and anthropogenic activities. With the gut microbiota critically modulating animal health, including stress tolerance, gut microbial interventions may offer opportunities to improve nonmodel ectotherm resilience to such pressures. Developing such interventions requires knowledge of host-gut microbiota-environment interactions that is critically lacking for most species and needs establishing. The roundworm Caenorhabditis elegans is emerging as a powerful ectotherm model to study host-gut microbiota interactions. Extensively utilized across research fields, C. elegans offers a breadth of resources and methodologies, including bioengineering technologies, defined microbiotas, and host and microbial isolate collections. In this review, we recapitulate C. elegans uses in gut microbiota studies, highlighting strengths and limitations and how it may accelerate mechanistic study of nonmodel ectotherm microbiotas. We notably propose a C. elegans-based strategy to identify, isolate, and study isolates from nonmodel ectotherm species to design microbial interventions that may promote climate resilience in nonmodel species.","PeriodicalId":12201,"journal":{"name":"FEMS microbiology reviews","volume":" ","pages":""},"PeriodicalIF":16.9,"publicationDate":"2026-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13484017/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148419766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In mammals, START domain proteins have been extensively characterized as key mediators of nonvesicular lipid transport and lipid-dependent signalling pathways. In contrast, the prevalence, structural diversity, and functional roles of START domain proteins in bacteria remain underexplored and for those that are characterized, experimental findings are occasionally conflicting. While bacterial START domains preserve the core helix-grip fold for lipid binding, they are typically smaller and exhibit more limited conformational flexibility than their eukaryotic counterparts. Despite these apparent constraints, available experimental data suggest that bacterial START domains participate in a remarkably broad range of biological processes-including small-molecule binding, metabolic regulation, enzymatic catalysis, and stress adaptation-rather than traditional lipid transport. Bacteria within the phylum Actinomycetota, in particular, have evolved a prolific repertoire of START-domain proteins. As an example, we will discuss the START domain proteins of Mycobacterium tuberculosis in detail, one of which has emerged as a promising drug target. Collectively, this synthesis underscores the functional versatility of the START domain across the domains of life and identifies critical knowledge gaps that warrant further investigation.","PeriodicalId":12201,"journal":{"name":"FEMS microbiology reviews","volume":" ","pages":""},"PeriodicalIF":16.9,"publicationDate":"2026-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13525633/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148790177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
