Digital health technologies are increasingly embedded into LTCI, and yet the pathways in which they are embedded and their governance effects differ across institutional contexts. This comparative review synthesizes evidence from Japan, South Korea, and China across five operational domains-institutional foundations, eligibility determination, service management, fund oversight, and policy steering-and uses a sociotechnical systems lens to analyze how technology and institutions co-evolve. We propose a three-layer model of institutional embedding linking welfare-boundary constraints, governance mechanisms shaping data-driven operations, and path dependence in policy and implementation. In the three countries, digital health technologies have not fundamentally expanded the welfare boundary of LTCI, but they have reshaped how LTCI is administered, shifting i) needs assessment from experience-led judgment toward data-driven decision-making support, ii) service management from flexible discretion toward rules and platform-based coordination, and iii) oversight from ex post auditing toward process-oriented monitoring. Distinct national pathways have emerged: a supplementary-technology pathway in Japan, a state-led integration pathway in South Korea, and an exploratory co-evolutionary pathway in China. These benefits are accompanied by practical risks, including algorithmic bias, inconsistent data quality, privacy and security concerns, and potential erosion of institutional flexibility. The proposed model helps explain cross-national divergence and provides a governance-oriented basis for selecting embedding strategies and safeguards in different LTCI contexts.</p>","PeriodicalId":8957,"journal":{"name":"Bioscience trends","volume":" ","pages":""},"PeriodicalIF":5.0,"publicationDate":"2026-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147760678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Japan, the practice of LT is uniquely shaped by the predominance of living donor transplantation and a marked epidemiological transition: the burden of viral hepatitis-related cirrhosis has declined with antiviral therapies, while metabolic dysfunction-associated steatohepatitis (MASH) and alcohol-associated liver disease (ALD) are emerging as leading indications.

Transient receptor potential ankyrin 1 (TRPA1) has been implicated in inflammation and pain, but its role in UC remains a subject of debate. The current study investigated the effects of TRPA1 inhibition in both acute and subacute murine models of dextran sulfate sodium (DSS)-induced colitis. Genetic knockout of Trpa1 or pharmacological inhibition with A967079 significantly ameliorated inflammation in the acute model, reducing the disease activity index (DAI), colon shortening, histopathological damage, and TNF-α secretion from macrophages. In contrast, TRPA1 suppression exacerbated subacute colitis and worsened weight loss, DAI, colon shortening, and histopathology. Mechanistically, Trpa1 deletion promoted CD4+ T cell polarization toward the Th1 subtype in subacute colitis, increasing IFN-γ levels. These findings reveal a dual role for TRPA1 in colonic inflammation: it mediates pro-inflammatory effects primarily via innate immune cells in the acute phase but has anti-inflammatory effects by modulating adaptive immunity in the subacute phase.
