Excessive production of reactive oxygen species (ROS) because of gut microbiome dysbiosis—one of the hallmark features of IBD—promotes chronic inflammation and facilitates the transformation of normal cells into senescent cells. Cellular senescence is associated with the development of various chronic and age-related diseases. We hypothesise that senolytic agents, specifically dasatinib (D) and quercetin (Q), could have a beneficial effect on both the gut microbiome and intestinal cells in IBD. The modulatory effects of a combination of <em>D</em> + <em>Q</em> was assessed in the M-SHIME model with faecal microbiota sourced from Crohn's disease patients. <em>D</em> + <em>Q</em> significantly modulated butyrate and lactate levels in the samples from specific patients. In addition, metabolomic analysis showed that <em>D</em> + <em>Q</em> positively impacted the abundance of anti-inflammatory bacteria while also significantly reducing the several species of pathogenic bacteria. Findings from a Caco-2 cell/THP1 co-culture model of IBD demonstrated that <em>D</em> + <em>Q</em> exerted strong immunomodulatory effects on the gut epithelium, evidenced by reduced NF-kB activity, and lower levels of the pro-inflammatory markers TNF-α, CXCL-10, and MCP-1. Furthermore, <em>D</em> + <em>Q</em> induced the secretion of anti-inflammatory cytokines, including IL-6 and IL-10. However, it should be noted that <em>D</em> + <em>Q</em> also led to the secretion of the pro-inflammatory cytokines IL-8. These findings suggest that <em>D</em> + <em>Q</em> could offer a novel therapeutic approach for advanced IBD management by modulating both the gut microbiome and inflammatory pathways.

However, we previously reported that systemic infusion of ChAT+ve Jurkat T cells into adult mice elicits vasodilation and instantaneous decline in the mean systolic blood pressure, suggesting potential as a biologic therapeutic to attenuate pathologic increases in pulmonary arterial pressures. We now report that ChAT gene-expressing Jurkat cells dose-dependently decrease right ventricular systolic pressures (RVSP) in hypoxic mice and that transgenic mice with ChAT KO restricted to endothelial cells (KO END/ChAT-/-) exhibit significantly elevated pulmonary arterial pressure and peripheral systemic resistance (compared to WT mice). To rigorously characterize the role of CD4 ChAT+ T cells in regulating pulmonary arterial hypertension (PAH) hemodynamics and molecular signatures, we infused CD4+ ChAT+ve cells (0.5 to 2.0 million cells/animal) into adult PAH mice and noted significant reductions in RVSP within 2-3 min post injection (∼ 50 % reduction). The tailored tail vein injection effect was sustained until the animal was euthanized (30-40 min). Mice KO END/ChAT-/-showed a significant and severe hypoxia-induced PAH phenotype compared to WT adult mice. Tail vein injection of biologically active CD4 ChAT+ve cells into either KO END/ChAT-/-mice with hypoxia-induced PAH or into adult rats with hypoxia/Sugen-induced PAH resulted in significant attenuation of RVP elevations. RNA seq data analysis of human pulmonary endothelial cells (HPAECs) incubated with CD4 ChAT+ve T cells showed significant differential regulation of pathways involved in systemic and pulmonary pressure regulation, NO synthesis/regulation, antioxidant expression, and vasodilation. In conclusion, CD4 ChAT+ve T cells have a unique, vasodilating innate immunity mechanism to augment nitric oxide release and potentially mitigate molecular and genetic pathways involved in PAH pathogenesis.</div></div>","PeriodicalId":23226,"journal":{"name":"Translational Research","volume":"278 ","pages":"Pages 22-35"},"PeriodicalIF":6.4,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143443109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

AKI manifests with extensive cellular damage, necrosis, and an intense inflammatory response, often leading to late-stage interstitial fibrosis. Although the mechanisms underlying renal injury and repair remain poorly understood, macrophages (pivotal inflammatory cells) play central roles in AKI. They undergo polarization into pro-inflammatory and anti-inflammatory phenotypes, contributing dynamically to both the injury and repair processes while maintaining homeostasis. Macrophages modulate microenvironmental inflammation by releasing extracellular vesicles (EVs) containing pro- or anti-inflammatory signaling molecules, thereby influencing the regulation of tissue injury. The injured tissue cells release EVs and activate local macrophages to initiate these responses. Our bibliometric analysis indicated that a shift has occurred in AKI macrophage research towards therapeutic strategies and clinical translation, focusing on macrophage-targeted therapies, including exosomes and nanoparticles. This review highlights the roles and mechanisms of macrophage activation, phenotypic polarization, and trans-differentiation in AKI and discusses macrophage-based approaches for AKI prevention and treatment. Understanding the involvement of macrophages in AKI contributes to the comprehension of related immune mechanisms and lays the groundwork for novel diagnostic and therapeutic avenues.</div></div>","PeriodicalId":23226,"journal":{"name":"Translational Research","volume":"278 ","pages":"Pages 1-9"},"PeriodicalIF":6.4,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143418852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the causal association between mitochondria-related genes and IPF remains to be determined. We obtained gene expression, protein abundance, and methylation quantitative trait locus data for mitochondria-related genes from previous studies. Genome-wide association study data for patients with IPF were obtained from the FinnGen study. A two-sample Mendelian randomisation analysis was conducted to assess the association between mitochondria-related genes and IPF. Furthermore, we conducted validation of expression differences utilizing transcriptome data derived from the BLM-induced pulmonary fibrosis mouse model (n=15). Concurrently, multiphoton imaging was utilized to quantify collagen contents and structural assessment. The direction of causality was verified using the Steiger test, and colocalisation analysis was used to better validate causality. Single-cell data were used to explore the localisation and expression of positive genes across different cell types. The study identified significant associations between mitochondria-related genes and IPF, with <em>POLG</em> and <em>NDUFB10</em> classified as Grade 1; <em>LYRM4, NBR1</em>, and <em>ACSF3</em> as Grade 2; <em>MCL1, GFER, MFN2, IVD</em>, and <em>SLC25A35</em> as Grade 3; and <em>METAP1D</em> and <em>MTX1</em> as Grade 4. Single-cell analysis showed elevated expression of <em>NBR1, MCL1</em>, and <em>MTX1</em> in pulmonary myofibroblasts of IPF. This study elucidated the causal effects of mitochondria-related genes on IPF, underscoring their significance in pathogenesis. These findings contribute to an improved understanding of the mechanisms underlying IPF, offering new potential therapeutic targets for interventions.</div></div>","PeriodicalId":23226,"journal":{"name":"Translational Research","volume":"278 ","pages":"Pages 10-21"},"PeriodicalIF":6.4,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143426815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
