Background And Aims: The beneficial effect of pre-treatment with unfractionated heparin (UFH) at first medical contact (FMC) before primary percutaneous coronary intervention (PPCI) in all-comers with ST-elevation myocardial infarction (STEMI) remains uncertain.

Methods: HELP-PCI was an investigator-initiated, randomized controlled trial conducted at 36 clinical centres in China. Patients with STEMI presenting ≤12 h after symptom onset undergoing PPCI were randomly assigned (1:1) to intravenous administration with UFH (100 U/kg) at FMC or in the Cath Lab through a catheter sheath.

This study aimed to compare the postoperative function of patients with critical coronary artery lesions undergoing intervention guided by intravascular ultrasound (IVUS) vs those guided by fractional flow reserve (FFR). A total of 226 patients (293 lesions) with coronary angiography-confirmed stenosis of 40% to 70% were enrolled and divided into 3 groups: the IVUS-guided group (98 lesions), the FFR-guided group (101 lesions), and the medical treatment group (94 lesions). In the IVUS-guided group, coronary stent implantation was performed if the minimum lumen area at the stenosis was < 4 mm2.

Antimicrobial peptides (AMPs) are attractive candidates to combat antibiotic resistance for their capability to target biomembranes and restrict a wide range of pathogens. It is a daunting challenge to discover novel AMPs due to their sparse distributions in a vast peptide universe, especially for peptides that demonstrate potencies for both bacterial membranes and viral envelopes. Here, we establish a de novo AMP design framework by bridging a deep generative module and a graph-encoding activity regressor.

Hantaan Orthohantavirus (Hantaan virus, HTNV) infection causes hemorrhagic fever with renal syndrome (HFRS) in humans, posing a significant health threat. Currently, there are no long-lasting protective vaccines or specific antivirals available, creating an urgent need for effective antiviral treatments in the clinical management of HFRS. Given that viruses exploit multiple host factors for their replication, host-oriented inhibitors could offer promising therapeutic options.

NLRX1 is an important regulator of inflammatory signaling in innate immune cells. Recent studies indicate NLRX1 activation may be a novel mechanism for inflammatory diseases, however, it has not been explored in atopic dermatitis (AD). Our study aims to investigate the potential role of NLRX1 in the pathogenesis of AD.

Virus budding is a critical step in the replication cycle of enveloped viruses, closely linked to viral spread, disease progression, and clinical outcomes. The budding of many enveloped RNA viruses is facilitated by the hijacking of the host endosomal sorting complex required for transport (ESCRT) proteins through viral late domains. These late domains are essential for progeny virus production and are highly conserved, making the interaction between late domains and host ESCRT proteins a potential target for the development of antiviral therapeutics.

Objective To confirm that Hantaan virus (HTNV) can infect BEAS-2B human normal lung epithelial cells and examine the host immune response and metabolic changes induced by HTNV infection by transcriptomic analysis. Methods Western blotting, quantitative real-time PCR and immunofluorescence assay were used to assess the viral load in BEAS-2B cells, and RNA sequencing was employed for transcriptomic analysis. Results Following the infection of BEAS-2B cells with HTNV, there was an increase in the expression of HTNV nucleocapsid protein (NP) and small segment (S) over time.

Acacetin, a flavonoid derived compound has been recognized for its diverse biological activities, such as anti-oxidative and anti-inflammatory effects. Acute lung injury (ALI) is a severe condition characterized by respiratory insufficiency and tissue damage, commonly triggered by pneumonia and severe sepsis. These conditions induce an inflammatory response via Toll-like receptor 4 (TLR4) signaling activation.

Hantaan virus (HTNV) is a major public health concern due to its ability to cause hemorrhagic fever with renal syndrome (HFRS) in Eurasia. Symptoms of HFRS include fever, hemorrhage, immune dysfunction and renal impairment, and severe cases can be fatal. T cell-mediated adaptive immune responses play a pivotal role in countering HTNV infection.

Colorectal cancer (CRC) is a prevalent and aggressive malignancy with high mortality rates and significant risks to human well-being. Population-wide screening for tumor suppressor genes and oncogenes shows promise for reducing the incidence and fatality of CRC. Recent studies have suggested that NLRX1, an innate immunity suppressor, may play a role in regulating chronic inflammation and tumorigenesis.

Article Synopsis
  • The resurgence of hemorrhagic fever with renal syndrome (HFRS) has prompted the need for better and safer vaccines, as existing options in China and Korea are inadequate.
  • Researchers designed a new recombinant protein vaccine using bioinformatics and the S2 Drosophila expression system to improve protein expression and immune response.
  • The promising results from mouse models show that the new HFRS subunit vaccine stimulates strong immunity and could be a potential candidate for preventing HFRS in humans.

Hantavirus can cause hemorrhagic fever with renal syndrome (HFRS) in Eurasia and hantavirus pulmonary syndrome (HPS) in America, with high mortality and unknown mechanisms. Innate immunity is the host's first-line defense to bridge the acquired immunity against viral infections. However, hantavirus has evolved various strategies in both molecular and cellular aspects to evade the host's natural immune surveillance.

Hantaan virus (HTNV) infects humans and causes hemorrhagic fever with renal syndrome (HFRS). The development of well-characterized animal models of HFRS could accelerate the testing of vaccine candidates and therapeutic agents and provide a useful tool for studying the pathogenesis of HFRS. Because NLRC3 has multiple immunoregulatory roles, we investigated the susceptibility of mice to HTNV infection in order to establish a new model of HFRS.
