Choosing a sensible and specific tumor marker (TM) serving as target which is immobilized on sensor surface is a crucial step for a CC immunosensor. In addition, the transducer design involving optical, piezoelectric or electrochemical converting of antigen-antibody interaction in the analytical signals could be projected to achieve a maximal sensitivity, guarantying accuracy in the detection of CC. This review aims to describe more important TMs and transducers used for the development of immunosensors for CC. An overview of experimental articles published in the last decade designed to detect TM associated with CC, using optical, electrochemical and piezoelectric transductions mode are discussed. Although serological TM, such as SCCa, CEA and CA125 are still predominantly used, new biomarkers including the P16, MCM5 and PP1γ2 have been considered specific and reliable for CC diagnostic. Recently, new strategies such as multiplex assays and samples obtained directly from tumor tissue, as well self-sampling, have been proposed to overcome several limitations. Optical and electrochemical are the most popular transducers, and nanoparticles as electrochemical probes and sandwich assays have been the strategies for increasing the limit of detection and sensitivity of immunosensors for CC diagnostic.</p>","PeriodicalId":11076,"journal":{"name":"Current topics in medicinal chemistry","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143794914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diet, oxidative stress, and the gut microbiota all play critical roles in the development of AD. Recent studies suggested a bidirectional relationship between the gut and the brain, emphasizing the pivotal role of the gut microbiome in influencing cognitive functions. For instance, dysbiosis, a disruption in the balance of gut microbial communities, has been linked to neuroinflammation and the accumulation of amyloid-beta plaques, hallmark features of AD. Oxidative stress, arising from an imbalance between free radicals and antioxidants, contributes significantly to AD pathology. The molecular mechanisms through which oxidative stress impacts neuronal health and exacerbates the cognitive decline in AD patients are also relevant. Moreover, nutritional interventions emerge as promising strategies to modulate these inflecting factors. Dietary components, such as antioxidants, omega-3 fatty acids, and polyphenols, exhibit neuroprotective effects, potentially mitigating AD progression. In contrast, the Western diet has a high potential to abet AD onset. Mediterranean diet and/or intermittent fasting are more valuable diets that may help delay the AD onset or progression. Limitations like individual differences affect the efficacy of nutritional interventions. As a supporting therapy, personalized diets should be applied according to the patients' special needs/microbiomes in the future.
