Antimicrobial resistance (AMR) poses a formidable challenge to global health, with fluoroquinolones, a critical class of broad-spectrum antibiotics, facing increasing resistance. Gatifloxacin, a widely used fourth-generation fluoroquinolone, is a prime example of a drug whose efficacy is threatened by emerging resistance mechanisms. This review delves into the growing concern of gatifloxacin resistance and highlights the urgent need for innovative strategies to combat this escalating public health crisis. The necessity of rigorous healthcare monitoring for fluoroquinolones, including precise Therapeutic Drug Monitoring (TDM), is emphasized to optimize patient outcomes and mitigate the development of further resistance. Traditional monitoring techniques, such as chromatography and immunoassay, while effective, often suffer from limitations in terms of cost, complexity, and real-time applicability for routine clinical settings. This review provides a comprehensive overview of the current landscape of gatifloxacin detection, focusing on the significant advancements in electrochemical and optical sensor technologies at the nanoscale. We critically evaluate the underlying principles, performance characteristics, and limitations of existing sensor platforms. Furthermore, a detailed analysis of prevailing research gaps is presented, specifically highlighting the nascent exploration of advanced biosensing platforms like immunosensors, aptasensors, and FET-based devices for gatifloxacin. The absence of integrated Lab-on-Chip, microfluidic, and MEMS-based solutions, alongside the underutilization of next-generation materials such as MXenes, Transition Metal Dichalcogenides (TMDs), and rare earth metal oxides, is critically discussed. The untapped potential of Artificial Intelligence and Machine Learning (AI/ML) integration for enhanced sensor performance and the glaring lack of clinically validated point-of-care (POC) devices for TDM, particularly those adhering to USFDA Bioanalytical Device guidelines, are identified as critical avenues for future research. This review concludes by outlining the future prospects for developing cutting-edge, nanotechnological biosensors that are sensitive, selective, rapid, and cost-effective, ultimately contributing to better management of gatifloxacin therapy and bolstering global efforts against antimicrobial resistance.</p>","PeriodicalId":102,"journal":{"name":"RSC Advances","volume":" 40","pages":" 33018-33045"},"PeriodicalIF":4.6,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ra/d5ra04732c?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145036971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent success of adoptive T-cell transfer therapy (ACT) for various pathological conditions warrants development of more physiologically relevant <i>ex vivo</i> cell culture platforms. Electrospun (Espun) scaffolds hold promise for culturing cells by mimicking features of extracellular matrix (ECM). However, unlike traditional 2D culture, recovering cells from these fibrous scaffolds is challenging and poses a critical roadblock in their development as cell culture platforms. We used electrospun matrices to culture Jurkat T-cells and observed that the cells remain entrapped in these matrices, facilitating their growth and clustering, which are the key phenomena for their activation and expansion, especially in the context of adoptive cell therapy. Yet, their retrieval using the pipette-aided gentle aspiration method proved difficult. This challenge was amplified with stimulating (anti-CD3 antibody-coated) substrates. Our study compared different recovery strategies using enzymatic agents (Accutase and TrypLE) and non-enzymatic manual flushing to determine the most effective method. A comparable cell yield was obtained and the viability of recovered cells was found to be unaffected for all the methods tested. However, the unstimulated substrate had a significantly higher cell recovery than its stimulated counterpart. Further investigation revealed that cells recovered from scaffolds after enzymatic treatment with Accutase had better proliferation and clustering ability when compared with those cultured on 2D substrates.

We previously identified brown adipose tissue-derived extracellular nicotinamide phosphoribosyltransferase (eNAMPT) as a pathogenic factor in ALD, but the underlying mechanisms remained unclear. Here, we explored the role of eNAMPT on liver inflammation and evaluate the therapeutic potential of nicotinamide riboside (NR), a form of vitamin B3, as a potential nutritional intervention. We found that ethanol exposure significantly increased eNAMPT secretion from brown adipocytes (BACs) and elevated circulating eNAMPT levels in mice fed a chronic-plus-binge ethanol diet. RNA-seq analysis and rescue experiments showed that neutralizing eNAMPT reduced hepatic NLRP3 inflammasome activation and proinflammatory cytokine expression. In the co-culture experiment, BACs-derived eNAMPT induced NLRP3 inflammasome activation in hepatocytes and macrophages. However, this effect was abolished when eNAMPT was depleted from the conditioned medium of BACs. Furthermore, recombinant eNAMPT exerts a dose-dependent effect on the activation of the NLRP3 inflammasome in hepatocytes and macrophages. Importantly, oral supplementation with NR effectively suppressed ethanol-induced eNAMPT secretion and mitigated hepatic NLRP3 activation both <i>in vivo</i> and <i>in vitro</i>. The secretion of eNAMPT was inhibited when NAMPT was knocked down in BACs, thereby attenuating the anti-inflammatory effect of NR, indicating its protective effect is dependent on targeting eNAMPT secretion.
