These hemocytes, called periostial hemocytes, phagocytose pathogens and produce immune factors on the abdominal portion of the dorsal vessel, called the heart. One of these immune factors, nitric oxide, is a pleiotropic free radical that is an antimicrobial and a heartbeat reducer. But nitric oxide is not just produced by hemocytes. It is also synthesized by pericardial cells that flank the heart, and other tissues. To determine whether it is the periostial hemocytes or the pericardial cells that modulate the heart following infection, we chemically ablated the hemocytes using clodronate liposomes and measured immune responses and heart physiology. We demonstrate that clodronate liposomes ablate the sessile hemocytes, including the periostial hemocytes, while leaving the pericardial cells and heart integrity unaffected. Moreover, ablating hemocytes abolishes the phagocytosis of bacteria, alters the deposition of melanized bacteria, and decreases nitric oxide synthase activity on the heart. Importantly, hemocyte ablation eliminates the infection induced reduction of the heart rate, mainly by modifying the anterograde heart rate. Therefore, periostial hemocytes drive immune responses on the heart and infection-induced changes to circulatory physiology.</p>","PeriodicalId":9712,"journal":{"name":"Cell and Tissue Research","volume":" ","pages":"173-188"},"PeriodicalIF":2.9,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12594744/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145085146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite adequate IOP control, many patients continue to progress to irreversible optic neuropathy, emphasising the need for alternate treatments. Transforming growth factor-beta (TGF-β) promotes extracellular matrix (ECM) production and fibrosis at the optic nerve head (ONH) in glaucoma. A disintegrin and metalloprotease-12 and metalloprotease-19 (ADAM12 and ADAM19) are implicated in fibrosis. Recent studies have explored miRNA-based manipulation of the TGF-β signalling pathway as a potential therapeutic strategy in fibrosis. This study investigates whether miR-29b modulation affects ADAM12, ADAM19, and ECM gene expression in human lamina cribrosa (LC) cells. Primary human normal lamina cribrosa (NLC) and glaucoma LC (GLC) cells were treated with TGF-β1 and transfected with either a miR-29b mimic or control. Gene expression levels of ADAM12, ADAM19, miR-29b, and several ECM genes were quantified using real-time RT-qPCR, and protein expression levels by Western blotting. ADAM12 and ADAM19 expression was elevated in untreated GLC cells, and treatment with TGF-β1 in both NLC and GLC cells increased ADAM12 and ADAM19 expression. The expression of miR-29b was significantly reduced in both GLC- and TGF-β1-treated NLC and GLC cells. Transfection with miR-29b resulted in a marked reduction in ADAM12 and ADAM19 mRNA expression in TGF-β1-treated NLC and GLC cells. Additionally, miR-29b transfection reduced ECM gene expression in both NLC and GLC under TGF-β1 stimulation. Our results demonstrate that miR-29b plays a crucial role in fibrotic remodelling at the LC by antagonising the effects of TGF-β1 on ADAM and ECM gene expression, representing a novel therapeutic target in glaucoma.</p>","PeriodicalId":9712,"journal":{"name":"Cell and Tissue Research","volume":" ","pages":"201-214"},"PeriodicalIF":2.9,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145111494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Parvin, a conserved but less explored IAP, forms a ternary complex with ILK and PINCH (the IPP complex). Although the IPP complex is functionally conserved, playing a central role in integrin-mediated adhesion, its individual components may also exert independent roles. The present study investigates parvin as a critical regulator of IFM function and sarcomeric integrity. Downregulation of parvin in IFM leads to altered sarcomere organisation and lowered accumulation of essential thin filament genes, including Act88F, wupA, up, TpnC4, and TM2 transcripts. Furthermore, Z-disc-associated proteins such as Zasp52 and its binding partner α-actinin, which are vital for myofibril stability, showed markedly reduced expression in parvin-deficient muscles. Notably, Zasp52 failed to localise to the Z-discs in IFMs, despite being detectable in leg muscles, suggesting tissue-specific mislocalisation. The expression of sallimus, a titin orthologue contributing to muscle elasticity, remained unchanged. Our findings underscore parvin's essential role in preserving IFM ultrastructure and function. We also emphasise the importance of maintaining the stoichiometric balance within the IPP complex-including its extended member Ras suppressor 1 (RSU1)-for proper muscle performance. Additionally, perturbation of parvin expression in a tissue-specific manner revealed its broader role in fly viability and muscle-driven behaviours, including larval locomotion and leg muscle function.

In general, immunohistochemistry with an anti-acetylated α-tubulin antibody is often used to visualize primary cilia. α-Tubulin is highly acetylated throughout podocytes, and this antibody is not suitable to determine the presence or absence of primary cilia in podocytes, which is one reason why the presence of primary cilia in podocytes has remained unclear. In the present study, we determined the presence or absence of primary cilia in mature podocytes of six vertebrate species using a recently reported array tomography workflow optimized for whole glomerulus analysis. The proportion of podocytes with primary cilia tended to decrease with evolution as follows: 89.6% in river lampreys (Agnatha), 42.1% in zebrafish (Osteichthyes), 43.3% in African clawed frogs (Amphibia), 17.3% in Reeves' turtles (Reptilia), 10.4% in common quails (Aves), and 0.0% in Wistar rats (Mammalia).
