The levels of metal ions vary widely across environments; many areas of the open ocean are chronically metal-limited, whereas other natural and human-affected environments have exceptionally high metal concentrations. Within the human host, the fitness of commensal and pathogenic microorganisms can be constrained by both metal limitation and intoxication. Limitation occurs when metals are deficient or in forms not suitable for import. Conversely, metal excess can lead to toxicity; microorganisms then rely on metal export to maintain suitable intracellular levels. Metalloregulatory systems play a central part in enabling microorganisms to acclimate to changes in metal availability. The analysis of metalloregulators and their regulons unveils physiologically relevant transport and trafficking functions, reveals processes affected by metal imbalance and provides insights into intracellular metal pools. In this Review, I explore the key processes of metal transport, trafficking, storage and regulation. I next highlight selected microorganisms that illustrate how to thrive in environments that are chronically or transiently metal-limited, or where high metal levels are toxic. A detailed understanding of microbial metal physiology can be harnessed to improve the health of diverse ecosystems, for bioremediation and biomining, and to restrict the growth of bacterial pathogens.</p>","PeriodicalId":18838,"journal":{"name":"Nature Reviews Microbiology","volume":"20 1","pages":""},"PeriodicalIF":88.1,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lactobacilli comprise all bacteria previously assigned to the <i>Lactobacillus</i> genus and, similar to other lactic acid bacteria, are characterized by their saccharolytic, fermentation-energy metabolism and diverse enzymatic pathways that support redox balance and maintain intracellular pH. Some lactobacilli are pervasive in dairy, meat and plant foods, where they either contribute to spoilage and food waste or are desired and necessary for the production of fermented foods and animal feed. Strains of lactobacilli are the most applied probiotics tested in clinical studies. The study of host-associated intestinal and vaginal microbiomes has demonstrated that lactobacilli drive epithelial and immune cell responses, resulting in mainly beneficial effects on host health. This Review explores both established and emerging concepts related to this group of microorganisms. It highlights central tenants of their genetic diversity, metabolism, stress tolerance and distribution across host-associated microbiomes, as well as their importance in fermented foods and in health modulation as probiotics. With this accumulated knowledge, there remain substantial opportunities for expanded application of lactobacilli across different domains relevant to food production and health.</p>","PeriodicalId":18838,"journal":{"name":"Nature Reviews Microbiology","volume":"37 1","pages":""},"PeriodicalIF":88.1,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144684467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Monoclonal neutralizing antibodies can be administered therapeutically to people living with HIV-1 and preventively to those who are uninfected and at risk. Neutralizing antibodies block viral entry into susceptible cells by targeting the HIV-1 envelope glycoprotein, which mediates entry by membrane fusion. The envelope glycoprotein evades neutralizing antibody responses by multiple means, including extreme sequence variation and a dense protective glycan shield. Despite these impediments, many broadly active neutralizing human antibodies have been isolated, typically after years of HIV-1 infection. In this Review, we describe how such antibodies target distinct epitope clusters that cumulatively now cover most of the external surface of the envelope glycoprotein. These antibodies vary in potency, in the degree to which they reduce infectivity, in mechanism of action, and in structural basis, affinity and kinetics of binding. Broadly neutralizing antibody responses have, however, so far not been elicited by immunization with envelope glycoproteins. That situation may change though with the rapid advancement of structure-guided immunogen design strategies that engage germline versions of human antibodies and guide their maturation towards greater neutralization potency and breadth.</p>","PeriodicalId":18838,"journal":{"name":"Nature Reviews Microbiology","volume":"277 1","pages":""},"PeriodicalIF":88.1,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144684531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
