Abstract
Fibrinolytic agents catalyze the conversion of the inactive proenzyme plasminogen into the active protease plasmin, degrading fibrin within the thrombus and recanalizing occluded vessels. The history of these medications dates to the discovery of the first fibrinolytic compound, streptokinase, from bacterial cultures in 1933. Over time, researchers identified two other plasminogen activators in human samples, namely urokinase and tissue plasminogen activator (tPA). Subsequently, tPA was cloned using recombinant DNA methods to produce alteplase. Several additional derivatives of tPA, such as tenecteplase and reteplase, were developed to extend the plasma half-life of tPA. Over the past decades, fibrinolytic medications have been widely used to manage patients with venous and arterial thromboembolic events. Currently, alteplase is approved by the U.S. Food and Drug Administration (FDA) for use in patients with pulmonary embolism with hemodynamic compromise, ST-segment elevation myocardial infarction (STEMI), acute ischemic stroke, and central venous access device occlusion. Reteplase and tenecteplase have also received FDA approval for treating patients with STEMI. This review provides an overview of the historical background related to fibrinolytic agents and briefly summarizes their approved indications across various thromboembolic diseases.

J Mol Histol 2024; 55:349-357.

Abstract
Stroke is a cerebrovascular disease that threatens human health. Developing safe and effective drugs and finding therapeutic targets has become an urgent scientific problem. The aim of this study was to investigate the effect of oxygen-glucose deprivation of the microglia-derived exosome on hippocampal neurons and its relationship to miR-124 in the exosome. We incubated hippocampal neurons with exosomes secreted by oxygen-glucose deprivation/ reoxygenation (OGD/R) microglia. The levels of glutamic acid (GLU) and gamma-aminobutyric acid (GABA) in the culture supernatant were detected by ELISA. CCK-8 was used to measure neuronal survival rates. The mRNA levels of TNF-α and IL-6 were detected by RT-qPCR to evaluate the effect of exosomes on neurons. RT-qPCR was then used to detect miR-124 in microglia and their secreted exosomes. Finally, potential targets of miR-124 were analyzed through database retrieval, gene detection with dual luciferase reporters, and western blotting experiments. The results showed that the contents of GLU, TNF-α and IL-6 mRNA increased in the supernatant of cultured hippocampal neurons, the content of GABA decreased, and the survival rate of neurons decreased. Oxygen-glucose deprivation increases miR-124 levels in microglia and their released exosomes. miR-124 acts as a target gene on cytokine signaling suppressor molecule 1(SOCS1), while miR-124 inhibitors reduce the expression of TNF-α and IL-6 mRNA in neurons. These results suggest that oxygen- and glucose-deprived microglia regulate inflammatory cytokines leading to reduced neuronal survival, which may be achieved by miR-124 using SOCS1 as a potential target.

[PMID: 38367449 DOI: 10.1016/j.compbiomed.2024.108141] [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: 10/09/2023] [Revised: 01/03/2024] [Accepted: 02/12/2024] [Indexed: 02/19/2024]
Abstract
The synergistic advantage of combining tissue plasminogen activator (tPA) with pro-urokinase (proUK) for thrombolysis has been demonstrated in several in vitro experiments, and a single site proUK mutant (m-proUK) has been developed for better stability in plasma. Based on these studies, combination thrombolytic therapy with intravenous tPA and m-proUK has been suggested as a promising treatment for patients with ischemic stroke. This paper evaluates the efficacy and safety of the dual therapy by computational simulations of pharmacokinetics and pharmacodynamics coupled with a local fibrinolysis model. Seven dose regimens are simulated and compared with the standard intravenous tPA monotherapy. Our simulation results provide more insights into the complementary reaction mechanisms of tPA and m-proUK during clot lysis and demonstrate that the dual therapy can achieve a similar recanalization time (about 50 min) to tPA monotherapy, while keeping the circulating fibrinogen level within a normal range. Specifically, our results show that for all dual therapies with a 5 mg tPA bolus, the plasma concentration of fibrinogen remains stable at around 7.5 μM after a slow depletion over 50 min, whereas a rapid depletion of circulating fibrinogen (to 5 μM) is observed with the standard tPA therapy, indicating the potential advantage of dual therapy in reducing the risk of intracranial hemorrhage. Through simulations of varying dose combinations, it has been found that increasing tPA bolus can significantly affect fibrinogen level but only moderately improves recanalization time. Conversely, m-proUK doses and infusion duration exhibit a mild impact on fibrinogen level but significantly affect recanalization time. Therefore, future optimization of dose regimen should focus on limiting the tPA bolus while adjusting m-proUK dosage and infusion rate. Such adjustments could potentially maximize the therapeutic advantages of this combination therapy for ischemic stroke treatment.
