Three important strategies have been explored in previous studies: (1) interruption of the interaction between ACE2 and the coronavirus spike protein using compounds or monoclonal antibodies, (2) capturing the extracellular virus by employing soluble ACE2 as a decoy, and (3) reducing the expression or inhibiting the activity of ACE2 through genetic approaches or drug intervention. However, the third strategy of inhibiting ACE2 activity as a means of treating COVID-19 is potentially risky, and the wisdom of pursuing this approach is subject to debate. Here, the advisability of using anti-ACE2 treatment in the context of SARS-CoV and SARS-CoV-2 infections is challenged by reviewing the physiological function of ACE2 and the mechanism of viral entry, emphasizing the pathological impairment of ACE2 that occurs during SARS-CoV and SARS-CoV-2 infection and arguing that the potential hazards associated with ACE2 impairment should be given more attention.

It is considered a neglected tropical disease that has the potential to cause sporadic epidemics in naive populations. Despite the substantial investment in research, there are no approved antiviral treatments for chikungunya. Several screening approaches have been used to identify potential antiviral molecules that target the whole virus, viral proteins, and viral-host interactions, often in conjunction with computational studies. The genome of chikungunya virus (CHIKV) encodes four nonstructural and five structural proteins. The capsid protein (CP) is a small structural protein with enzymatic activity. Owing to its critical role in different stages of the viral life cycle, the CP can be targeted at multiple stages, thereby impeding viral multiplication. There is evidence suggesting that the CP may be a promising target for drug development, and this has led to the discovery of various inhibitors through diverse in vitro and in silico analyses. Both cell-based and cell-free assays have been widely used to identify and evaluate CHIKV CP inhibitors. Computer-based studies targeting CHIKV proteins, including CP, have identified several lead compounds, which are being further evaluated in various in vitro systems. No review has been published on the CHIKV CP, and papers have focused on drug development and the targeting of viral proteins and associated factors. In this review, we summarize the research that has been conducted on the CHIKV CP, including structural studies, antiviral research, and prospects for the use of the CP as an antiviral target.</p></div>","PeriodicalId":8359,"journal":{"name":"Archives of Virology","volume":"170 7","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144140310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PEDV is an enveloped virus that enters cells via endocytosis, a process that is dependent on the binding of the viral surface S protein to a receptor on the host cell membrane. This results in a series of biomechanical alterations that drive the fusion of the viral and host cell membranes. These alterations stabilise the binding of the virus to the receptor and also affect the tension and the curvature of the plasma membrane and the formation of endocytic vesicles. A comprehensive understanding of the mechanism by which PEDV enters cells and the biomechanical changes that accompany this process is of paramount importance for the development of PEDV inhibitors, vaccines, and disease prevention and control strategies. Here, we review the general mechanism of PEDV entry, the biomechanical phenomena that occur during endocytosis, and the potential applications of biomechanics in antiviral therapy.

Comparative genomic analysis showed a close relationship between the FMDV strains from this study and those reported in neighboring Asian countries.

Substantial variation was observed in polymorphic and monomorphic sites, with the highest diversity observed in the VP1 protein of serotype O viruses. No evidence of recombination events was found in the FMDV strains from this study.

Antigen-specific immune responses in mouse serum were evaluated via enzyme-linked immunosorbent assays (ELISAs), hemagglutination inhibition (HI) assays, and microneutralization (MN) assays. The effects and mechanisms of action of the adjuvants were further analyzed by analyzing mouse spleen germinal center (GC) cell activation via flow cytometry. MF59-like YD significantly increased the humoral immune responses induced by QIVs in mice, in particular, the titers of HI and MN antibodies against homologous and heterologous virus subtypes. Mechanistically, MF59-like YD increased the immune response to influenza vaccines by activating T follicular helper (Tfh) and B cells in the GC.
