Metal-enhanced fluorescence (MEF) is a photophysical phenomenon in which interactions between luminescent species and metal nanostructures markedly increase emission, enabling a route to brighter, high-contrast, noninvasive bioimaging by reshaping photophysical pathways without modifying fluorophore chemistry. This review translates MEF fundamentals into an experimental playbook for biologists, distinguishing MEF mechanisms and explaining how distance, spectral overlap, and nanoparticle morphology govern whether emission is boosted or quenched. We synthesize recent live-cell applications—using gold and silver nanoparticles—to illustrate gains in signal-to-noise at lower excitation power, improved photostability, and opportunities where small-molecule dyes often suffer low quantum yield, and provide practical guidelines for pairing dyes with metal nanostructures to lower the barrier to adopting MEF in cellular imaging.</p>","PeriodicalId":9264,"journal":{"name":"BioEssays","volume":"48 4","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13037458/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147580531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding and exploiting such differences could have clinical and translational potential. Here, we discuss the various mechanistic interactions between stem cells and viruses related to entry mechanisms, replication dynamics, and immunomodulation. In doing so, we critically assess proposed models and hypotheses about how viruses manipulate stem cell biology, while also providing new paradigms for stem cell biology and therapeutic interventions. We highlight recent discoveries on the dual role of viruses in oncogenesis and oncolysis. In parallel, we explore similarities between stem cells and complex viruses—such as giant viruses and jumbo phages—to propose novel perspectives on viral adaptability and pathogenesis. We examine both established mechanisms and emerging viral phenomena to encourage further research and debate on the clinical implications of viral interactions with stem cells.</p>\u0000 </div>","PeriodicalId":9264,"journal":{"name":"BioEssays","volume":"48 3","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147509568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many studies have described the importance of peptide/MHC motion or dynamics in TCR recognition. A role for dynamics in recognition intersects with the concept of dynamic allostery, which describes how alterations to a protein's energy landscape and thus motions influence function, often in the absence of conformational changes. Tuning of MHC protein energy landscapes by different peptides has clearly been shown. Evidence is mounting, however, that MHC polymorphisms also alter the protein's energy landscape. Here, we address this concept, summarizing findings that suggest that, in addition to dictating peptide binding and selection, naturally occurring variations within MHC proteins promote differential peptide and protein dynamics, altering TCR recognition in an MHC allele-dependent manner. We hypothesize that MHC polymorphisms have been selected evolutionarily in part to tune the protein's dynamic response, altering immune specificity and further diversifying immune responses across populations.</p>","PeriodicalId":9264,"journal":{"name":"BioEssays","volume":"48 3","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13015781/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147509374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While conventional models emphasize motor-driven cargo movement along stationary MT tracks, emerging evidence suggests that dynamic movements of MTs also contribute to directional transport. We propose a model of cargo co-migration with moving MTs, exemplified by nuclear migration in developing neurons. This transport mode may operate across cell types, provided that cargo-MT tethering and directional MT movements are present. We hypothesize multiple complementary mechanisms, including motor catch-bond formation and clustering, as well as MT-associated protein-mediated anchorage. We further discuss how directional MT movements can be generated through motor-driven sliding, cortical gliding, actin-MT crosslinking, and dynamic MT instability. This coupled transport mechanism provides an additional layer of directional control that supplements motor-stepping-dependent transport. Potential experimental approaches to validate this hypothesis are discussed. Understanding MT-mediated cargo delivery could refine our current models of intracellular transport and reveal new insights into neurodevelopmental and neurodegenerative disorders.</p>","PeriodicalId":9264,"journal":{"name":"BioEssays","volume":"48 3","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13015778/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147509593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
