In this study, we employed an ASD model combined with fear conditioning to investigate these mechanisms. mRNA sequencing revealed upregulated expression of Transient Receptor Potential Vanilloid 4 (TRPV4), a nonselective Ca<sup>2+</sup>-permeable cation channel critical for calcium signaling, in mice with ASD-induced memory impairments. Notably, TRPV4 knockdown reversed ASD-induced memory deficits. ASD was associated with increased intracellular Ca<sup>2+</sup> concentrations, reduced spine density, and decreased expression of postsynaptic density protein 95 (PSD95), a key regulator of synaptic plasticity. These findings suggest that ASD may cause Ca<sup>2+</sup> overload, leading to disrupted synaptic plasticity and impaired learning and memory. Importantly, TRPV4 knockdown significantly reduced Ca<sup>2+</sup> concentrations, mitigated synaptic plasticity impairments, and contributed to memory restoration. Together, these findings demonstrate a protective role of TRPV4 knockdown against ASD-induced memory deficits and highlight TRPV4 as a potential therapeutic target for memory impairment associated with ASD.</div></div>","PeriodicalId":72541,"journal":{"name":"Cell insight","volume":"4 3","pages":"Article 100240"},"PeriodicalIF":0.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143815800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The <em>Salmonella</em> type III secretion system (T3SS), encoded within its pathogenicity islands (SPIs), is critical for bacterial virulence by directly delivering multiple effectors into eukaryotic host cells. <em>Salmonella</em> utilizes these effectors to facilitate its survival and replication within the host through modulating cytoskeletal dynamics, inflammatory responses, the biogenesis of <em>Salmonella</em>-containing vacuole (SCV), and host cell survival. Moreover, these effectors also interfere with immune responses via inhibiting innate immunity or antigen presentation. In this review, we summarize the current progress in the survival strategies employed by <em>Salmonella</em> and the molecular mechanisms underlying its interactions with the host. Understanding the interplay between <em>Salmonella</em> and host can enhance our knowledge of the bacterium's pathogenic processes and provide new insights into how it manipulates host cellular physiological activities to ensure its survival.</div></div>","PeriodicalId":72541,"journal":{"name":"Cell insight","volume":"4 2","pages":"Article 100237"},"PeriodicalIF":0.0,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143643372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the field of RNA research, nanopore sequencing proves invaluable in discerning differentially expressed transcripts, uncovering novel elements linked to transcriptional regulation, and identifying alternative splicing events and RNA modifications at the single-molecule level. Furthermore, nanopore sequencing extends its reach to detecting microorganisms, encompassing bacteria and viruses, that are intricately associated with tumorigenesis and the development of cancer.
