The derivatives of hirudin-like peptides from the Poecilobdella manillensis exhibit antithrombotic and anti-ischemic stroke effects. Int J Biol Macromol 2025; 307:141950. [PMID: 40086559 DOI: 10.1016/j.ijbiomac.2025.141950] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2024] [Revised: 02/10/2025] [Accepted: 03/09/2025] [Indexed: 03/16/2025]
Abstract
Almost all currently approved anticoagulants interfere with hemostasis and increase the risk of bleeding complications. Thus, there is a critical need for safer anti-thrombotic drugs without bleeding risk. Hirudin has demonstrated potent antithrombotic properties, but is clinically limited due to its high bleeding risk. Hirudin variants such as bivalirudin have been developed to address this issue, yet present a similar proportional risk of bleeding. In this study, several hirudin-like peptides were identified from the salivary gland transcriptome of Poecilobdella manillensis. Guided by the structural design principles of bivalirudin, derivatives of these hirudin-like peptides were synthesized and evaluated for their antithrombotic efficacy and safety in thrombosis and ischemic stroke. Results suggested that derived peptides PM3, PM4, PM6 and PM7 can effectively inhibited the activity of thrombin in vitro. Furthermore, PM4, PM6 and PM7 exhibited robust anticoagulant activity in vivo. Importantly, PM4 and PM7 exhibited significantly lower bleeding risk compared to bivalirudin, as well as comparable efficacy in mitigating intracerebral thrombosis in a transient middle cerebral artery occlusion mouse model, without inducing intracerebral hemorrhage. These findings highlight the therapeutic potential of hirudin-like peptide derivatives as promising candidates for the treatment of thrombosis and ischemic stroke, combining efficacy with an improved safety profile.

Abstract
Scleroderma renal crisis (SRC) is an acute life-threatening manifestation of systemic sclerosis (SSc) caused by obliterative vasculopathy and thrombotic microangiopathy. Evidence suggests a pathogenic role of immunoglobulin G (IgG) targeting G-protein coupled receptors (GPCR). We therefore dissected SRC-associated vascular obliteration and investigated the specific effects of patient-derived IgG directed against angiotensin II type 1 (AT1R) and endothelin-1 type A receptors (ETAR) on downstream signaling events and endothelial cell proliferation. SRC-IgG triggered endothelial cell proliferation via activation of the mitogen-activated protein kinase (MAPK) pathway and subsequent activation of the E26 transformation-specific-1 transcription factor (Ets-1). Either AT1R or ETAR receptor inhibitors/shRNA abrogated endothelial proliferation, confirming receptor activation and Ets-1 signaling involvement. Binding of Ets-1 to the tissue factor (TF) promoter exclusively induced TF. In addition, TF inhibition prevented endothelial cell proliferation. Thus, our data revealed a thus far unknown link between SRC-IgG-induced intracellular signaling, endothelial cell proliferation and active coagulation in the context of obliterative vasculopathy and SRC. Patients' autoantibodies and their molecular effectors represent new therapeutic targets to address severe vascular complications in SSc.

Abstract
INTRODUCTION A hyper-coagulant state is a biological mechanism that triggers cardiac events in patients with coronary artery disease (CAD). Depressive symptoms and anxiety predict an unfavourable course of CAD. The SPIRR-CAD-RCT examined the effects of a psychological intervention and provided the opportunity to explore cross-sectional associations between indices of psychological strain and coagulation parameters, as well as prospective changes in depression scores and coagulation parameters. METHODS In this secondary analysis, we investigated 253 CAD patients (194 male; age m 58.9, SD 8.3 yrs.) with mild to moderate depression (≥8 on the HADS-D) at baseline and at follow-up 18 months later: TF, fibrinogen, D-dimer, VWF, FVII and PAI-1 and the course of depression (HAM-D), vital exhaustion (VE) and anxiety scores (HADS-A) were examined by ANOVA in the total and younger age groups (≤ 60). RESULTS HAM-D at baseline was correlated with TF (corr. R2 = 0.27; F = 9.31, p = 0.001). HADS anxiety was associated with fibrinogen (corr. R2.20; F = 7.27, p = 0.001). There was no detectable therapeutic effect on coagulation. Fibrinogen and VWF decreased within 18 months (time effect; p = 0.02; p = 0.04), as did HADS-D in both treatment groups (p < 0.001). Fibrinogen decreased more in patients ≤60 years with high VE compared to low VE (interaction time x group, p = 0.01). CONCLUSIONS This is the first study to show an association between TF and depression. Coagulation parameters as potential mediators of CAD progression correlated cross-sectionally with depression and anxiety and prospectively with VE. Further studies should replicate these correlations in depressed and non-depressed CAD patients. ISRCTN 76240576; clinicaltrials.gov.

Abstract
Platelet-derived microvesicles (pMVs) are small, heterogeneous vesicles released from platelet membranes as a result of activation. These microvesicles possess a wide range of properties, including prothrombotic, proatherogenic, proinflammatory, immunomodulatory, and even anticoagulant activity. The elevated release of these microvesicles has been observed in various metabolic, inflammatory, thrombotic, and vascular diseases, including ischemic heart disease, stroke, hypertension, diabetes, and connective tissue disease. Modulation of both pMV generation and the expression of their surface molecules may have beneficial clinical implications and could become a novel therapeutic target. However, mechanisms by which pharmacological agents can modify pMV formation are elusive. The purpose of this review is to discuss the effects of drugs routinely used in primary and secondary prevention of vascular disease on the release of pMV and expression of their surface procoagulant and proinflammatory molecules.

Abstract
Thrombin (coagulation factor IIa) is a serine protease encoded by the F2 gene. Pro-thrombin (coagulation factor II) is cut to generate thrombin in the coagulation cascade that results in a reduction of blood loss. Procoagulant states that lead to activation of thrombin are common in bone fracture sites. However, its physiological roles and relationship with osteoblasts in bone fractures are largely unknown. We herein report various effects of thrombin on mouse osteoblastic MC3T3-E1 cells. MC3T3-E1 cells expressed proteinase-activated receptor 1 (PAR1), also known as the coagulation factor II receptor. They also produced monocyte chemoattractant protein (MCP-1), tissue factor (TF), MCSF and IL-6 upon thrombin stimulation through the PI3K-Akt and MEK-Erk1/2 pathways. Furthermore, MCP-1 obtained from thrombin-stimulated MC3T3-E1 cells induced migration by macrophage RAW264 cells. All these effects of thrombin on MC3T3-E1 cells were abolished by the selective non-peptide thrombin receptor inhibitor SCH79797. We also found that thrombin, PAR-1, MCP-1, TF as well as phosphorylated AKT and p42/44 were significantly expressed at the fracture site of mouse femoral bone. Collectively, thrombin/PAR-1 interaction regulated MCP-1, TF, MCSF and IL-6 production by MC3T3-E1 cells. Furthermore, MCP-1 induced RAW264 cell migration. Thrombin may thus be a novel cytokine that regulates several aspects of osteoblast function and fracture healing.

Abstract
Background Although antiplatelet therapy involving clopidogrel is a standard treatment for preventing cardiovascular events after coronary stent implantation, patients can display differential responses. Here, we assessed the effectiveness of clopidogrel on platelet function inhibition in subjects with and without type-2 diabetes and stable coronary artery disease. In addition, we investigated the correlation between platelet function and routine clinical parameters. Methods A total of 64 patients with stable coronary heart disease were enrolled in the study. Among these, 32 had known type-2 diabetes, whereas the remaining 32 subjects were non-diabetics (control group). A loading dose of 300 mg clopidogrel was given to clopidogrel-naïve patients (13 patients in the diabetes group and 14 control patients). All patients were given a daily maintenance dose of 75 mg clopidogrel. In addition, all patients received 100 mg ASA per day. Agonist-induced platelet aggregation measurements were performed on hirudin-anticoagulated blood using an impedance aggregometer (Multiple Platelet Function Analyzer, Dynabyte, Munich, Germany). Blood samples were drawn from the antecubital vein 24 h after coronary angiography with percutaneous coronary intervention. The platelets were then stimulated with ADP alone or ADP and prostaglandin-E (ADP and ADP-PGE tests, respectively) in order to evaluate clopidogrel-mediated inhibition of platelet function. The effectiveness of ASA was measured by stimulation with arachidonic acid (ASPI test). In addition, maximal platelet aggregation was assessed via stimulation with thrombin receptor-activating peptide (TRAP test). Results Patients with diabetes exhibited significantly less inhibition of platelet function than patients without diabetes (ADP-PGE test p = 0.003; ASPI test p = 0.022). Administering a clopidogrel loading dose of 300 mg did not result in a lower level of ADP-PGE-induced platelet reactivity in comparison to the use of a 75 mg maintenance dose. Moreover, we observed that ADP-PGE-induced platelet inhibition was positively correlated with fasting blood glucose and HbA1c (p < 0.01). Conclusions Patients with type-2 diabetes exhibited increased platelet reactivity compared to patients without diabetes despite combined treatment with clopidogrel and ASA. Using a loading dose of clopidogrel rather than small daily doses was not sufficient for adequately overcoming increased platelet reactivity in patients with type-2 diabetes, highlighting the need for more effective anti-platelet drugs for such patients.

Abstract
INTRODUCTION Myocarditis is induced by coxsackievirus B3 (CVB3). Myocardial inflammation is tied to the activation of coagulation. Coagulation factor (F) Xa, a central player in coagulation, activates matrix metalloproteinases (MMP), which modulate the remodeling. AIMS In this study, we investigated the effects of pharmacological FXa inhibition on myocardial function, inflammation, and remodeling during a CVB3-induced myocarditis. METHODS AND RESULTS Immune cells and matrix proteins were detected by immunohistochemistry. The expression of cytokines was measured by real-time PCR and the activity of MMP-2 by zymography. Left ventricular function was analyzed using microconductance pressure catheter. Treatment with the FXa inhibitor fondaparinux led to an improved left ventricular function in CVB3-induced mice compared to saline-treated controls (dPdtmax: fondaparinux 4632 ± 499.6 vs. saline 3131 ± 374.0 [mmHg/s], P = 0.0503; SV: fondaparinux 33.19 ± 4.893 vs. saline 19.32 ± 2.236 [μL], P < 0.118; CO: fondaparinux 15124 ± 2183 vs. saline 8088 ± 1035 [μL/min], P < 0.05). Therapy with fondaparinux reduced the activity of MMP-2 (fondaparinux 1.208 ± 0.1247 vs. saline 1.565 ± 0.05476, P < 0.05). The collagen type I/III ratio as well as the expression of TIMP-1 was comparable in both infection groups postinfectionem (p.i.), despite an increased infiltration of macrophages into the hearts of mice treated with fondaparinux 8 days p.i. (CD68+: fondaparinux 494.2 ± 64.73 vs. saline 306.9 ± 43.73 [cells/mm(2) ], P < 0.05). Anti-inflammatory CD206-positive M2-type macrophages were increased in the infected hearts after fondaparinux treatment (CD206+: fondaparinux 182.1 ± 18.18 vs. saline 111.6 ± 21.07 [cells/mm(2) ], P < 0.05), whereas CD80-positive M1-type macrophages were comparable in both groups. CONCLUSION In conclusion, selective inhibition of FXa improves the left ventricular function during CVB3-induced myocarditis and seems to be associated with an improved myocardial remodeling.

Abstract
Tissue Factor (TF) is an evolutionary conserved glycoprotein, which is of immense importance for a variety of biologic processes. TF is expressed in two naturally occurring protein isoforms, membrane-bound "full-length" (fl)TF and soluble alternatively spliced (as)TF. The TF isoform expression is differentially modulated on post-transcriptional level via regulatory factors, such as serine/arginine-rich (SR) proteins, SR protein kinases and micro (mi)RNAs. Both isoforms mediate a variety of physiologic- and pathophysiologic-relevant functions, such as thrombogenicity, angiogenesis, cell signaling, tumor cell proliferation and metastasis. In this review, we will depict the main mechanisms regulating the TF isoform expression in cancer and under other pathophysiologic-relevant conditions. Moreover, we will summarize and discuss the latest findings regarding the role of TF and its isoforms in cancer biology.

Abstract
Posttranscriptional control of gene expression is crucial for regulating plurality of proteins and functional plasticity of the proteome under (patho)physiologic conditions. Alternative splicing as well as micro (mi)RNA-mediated mechanisms play an important role for the regulation of protein expression on posttranscriptional level. Both alternative splicing and miRNAs were shown to influence cardiovascular functions, such as endothelial thrombogenicity and the vascular tone, by regulating the expression of several vascular proteins and their isoforms, such as Tissue Factor (TF) or the endothelial nitric oxide synthase (eNOS). This review will summarize and discuss the latest findings on the (patho)physiologic role of alternative splicing processes as well as of miRNAs on modulation of vascular functions, such as coagulation, thrombosis, and regulation of the vascular tone.

Abstract
Tissue factor (TF) and its isoforms play an important role in a variety of physiologic and pathophysiologic functions, such as initiation of blood coagulation, vessel wall hemostasis, angiogenesis, and tumorigenesis. Micro(mi)RNAs are crucial for post-transcriptional control of protein generation by regulating the expression of one-third of all human genes. In recent years, miRNAs were shown to modulate the expression and biologic function of TF in different physiologic- and pathophysiologic-relevant settings, such as in autoimmune diseases and in different types of cancer. In the present review, we will summarize and discuss the latest findings regarding the impact of miRNAs on the generation of TF and its isoforms as well as on regulation of TF biology under normal and pathophysiologic conditions.

Abstract
Islet and hepatocyte transplantation are associated with tissue factor-dependent activation of coagulation which elicits instant blood mediated inflammatory reaction, thereby contributing to a low rate of engraftment. The aim of this study was i) to evaluate the procoagulant activity of human adult liver-derived mesenchymal progenitor cells (hALPCs), ii) to compare it to other mesenchymal cells of extra-hepatic (bone marrow mesenchymal stem cells and skin fibroblasts) or liver origin (liver myofibroblasts), and iii) to determine the ways this activity could be modulated. Using a whole blood coagulation test (thromboelastometry), we demonstrated that all analyzed cell types exhibit procoagulant activity. The hALPCs pronounced procoagulant activity was associated with an increased tissue factor and a decreased tissue factor pathway inhibitor expression as compared with hepatocytes. At therapeutic doses, the procoagulant effect of hALPCs was inhibited by neither antithrombin activators nor direct factor Xa inhibitor or direct thrombin inhibitors individually. However, concomitant administration of an antithrombin activator or direct factor Xa inhibitor and direct thrombin inhibitor proved to be a particularly effective combination for controlling the procoagulant effects of hALPCs both in vitro and in vivo. The results suggest that this dual antithrombotic therapy should also improve the efficacy of cell transplantation in humans.
