- The formation of extracellular traps (ETs) through ETosis has emerged as a key mechanism in immunothrombosis. However, the temporal dynamics and clinical significance of ETosis in coronary thrombi of ST-elevation myocardial infarction (STEMI) patients remain incompletely understood. We investigated whether ETosis burden increases with thrombus age and is associated with and genetic variants as well as impaired myocardial reperfusion. Thrombus aspirates from 81 STEMI patients undergoing primary percutaneous coronary intervention were histologically classified as fresh ( = 41) or lytic ( = 40). ETosis was quantified by citrullinated histone H3 (CitH3) immunohistochemistry and digital image analysis, complemented by multiplex staining for myeloperoxidase (MPO), CD68, caspase 3, and CD61. Plasma ET-related markers and genotyping of (rs1053874) and (rs11797) were also performed. CitH3-positive cells were present in all thrombi but were more abundant in lytic (older) thrombi compared with fresh thrombi (1348 vs. 591 cells/mm, < 0.001). Increased ETosis was associated with neutrophil and macrophage infiltration, apoptosis, prolonged ischemia time, elevated systemic inflammation (neutrophil-lymphocyte ratio and C-reactive protein), and impaired myocardial reperfusion (lower TIMI flow grades). Moreover, the GG genotype was associated with higher densities of MPO- and CD68-positive cells, whereas the CC genotype was associated with increased densities of CitH3-, MPO-, and CD68-positive cells. This study demonstrates that ETosis increases with coronary thrombus maturation and is associated with local inflammation and impaired reperfusion in STEMI. Genetic variants in and may modulate inflammatory cell accumulation within thrombi. These findings suggest ETosis as a potential therapeutic target, particularly in patients with delayed presentation. - Source: PubMed

Wang DongyangBai FuweiWang ZhanqiHe JunningLi HaiyunZhou FengChen TaoXiang LinMan YiWu Yingying - Antiphospholipid syndrome (APS) is an immunothrombotic disorder, frequently attributed to autoantibodies that bind β2-glycoprotein I (β2GPI). A study showed that the platelet-specific chemokine, platelet factor 4 (PF4), binds to β2GPI, enhancing recognition of β2GPI by APS antibodies. APS antibodies induce the release of neutrophil extracellular traps (NETs), webs of decondensed chromatin that bind both PF4 and b2GPI. We propose that PF4 bridges β2GPI to NETs (and other PF4-targeted polyanions), leading to the formation of prothrombotic PF4:b2GPI:NET immunotargets in APS. Dynamic light-scattering studies of isolated IgGs from four patients with triple-positive APS show formation of PF4:β2GPI:NET complexes that bind APS antibodies. NETs released in a microfluidic system bound b2GPI, but only in the presence of PF4, forming a multimolecular APS antigenic target. Whole blood infused through a photochemically-injured, endothelium-lined microfluidic channel formed platelet-, fibrin-, and complement- rich thrombi that bound APS antibody only in the presence of PF4. Thrombi were reduced in size if either ADAMTS13 or DNase1 was infused. In a murine APS model, wildtype and transgenic mice expressing platelet human PF4 ± FcgRIIA developed more intense neutrophil rolling along veins, and more extensive thrombus formation following laser injury to cremaster arterioles and venules, whereas mice lacking PF4 did not. Three antigenically distinct anti-hPF4 monoclonal antibodies blocked thrombosis in vitro, and neutrophil rolling and thrombosis in vivo. Our studies provide new insights into the basis of APS that has mechanistic parallels to other known PF4 immunothrombotic disorders and offer potential diagnostic and non-anticoagulant therapeutic strategies for clinical management. - Source: PubMed

Traumatic HO is a disabling condition, potentially resulting in loss of joint function and compression of neurovascular structures. Available treatment options are often unsuccessful, frequently necessitating surgical resection of HO lesions with a high risk of recurrence. Given that myeloid cells, including neutrophils and macrophages, are among the first cell types to infiltrate injured tissue, the present study explored the relationship of extracellular traps (ETs) with HO formation in humans and mice. Human HO sample analysis revealed the presence of different stages of ETosis, which are clinically associated with increased ET concentrations in the blood. Experimentally, genetic impairment of ET resolution through combined and deficiency led to increased traumatic HO in mice, whereas HO was strongly attenuated by additional deletion of the ET generator . Neutrophil depletion impaired local ET formation, reduced HO formation, and blunted genotype-specific differences in HO outcome. In osteogenic precursors, ETs promoted matrix mineralization, and inhibition of ETosis or degradation of cell-free DNA, a major ET component, resulted in reduced osteogenesis. Pharmacological facilitation of ET clearance by dornase alfa, a US Food and Drug Administration-approved recombinant DNase1, or inhibition of ETs by the PADI4 inhibitor GSK484, resulted in inhibition of traumatic HO formation in mice without adversely affecting systemic bone remodeling. Together, our clinical and experimental findings demonstrate that traumatic HO is mediated by targetable neutrophil-dependent mechanisms, with altered ET formation contributing to these effects. - Source: PubMed

This study focused on developing and characterizing decellularized matrices decellularized extracellular matrix porcine skeletal muscle (dECM-pSM) for their potential use in oral mucosa restoration. A perfusion decellularization protocol was implemented on pSM segments, utilizing a combination of physical (perfusion), chemical (SDS), and enzymatic (DNase-1) agents over 18 d. The effectiveness of the process was evaluated macroscopically, through histological stains (H&E, DAPI, Masson's Trichrome), scanning electron microscopy, DNA quantification, and Fourier transform infrared spectroscopy. The thermal properties (TGA, DSC), swelling (S), and biocompatibility of the dECM-pSM with human gingiva fibroblast cells (HGF) were analyzed, including adhesion and viability assays. The results showed successful decellularization, with significant removal of nuclear material (0.7 ng mgresidual DNA) with preservation of the three-dimensional architecture of ECMs and physicochemical properties, as confirmed by histological integrity of the fiber and porous structures, preserved characteristic bands of amide groups, and stable thermal properties after the decellularization process. The dECM-pSM maintained their Scapacity (300% after 5 min) and demonstrated desirablebiocompatibility, promoting the adhesion at 92% after 2 d, and viability of 80% after 4 d of HGF compared to the control, without evidence of cytotoxicity. These results suggest that the developed protocol yields decellularized matrices with suitable properties for tissue engineering applications. - Source: PubMed
