These viruses manipulate mTOR complexes through specific viral proteins, such as DENV NS5 activating mTORC2 to suppress apoptosis and ZIKV NS4A/NS4B inhibiting Akt-mTORC1 signalling to impair neurogenesis while promoting autophagy. JEV NS1/NS1' disrupts the blood-brain barrier by inducing autophagy-mediated degradation of tight junction proteins via mTOR suppression, contributing to encephalitis. These interactions result in severe pathological outcomes, including immune evasion, metabolic reprogramming, apoptosis suppression, and neurological disorders like microcephaly. Targeting mTOR has emerged as a promising therapeutic approach for arbovirus infections. Rapamycin and its derivatives reduce viral replication and improve survival in preclinical models, while repurposed drugs like niclosamide and chloroquine exhibit antiviral effects against ZIKV. ATP-competitive inhibitors such as Torin-1 and natural compounds like resveratrol expand the therapeutic landscape. Combination therapies pairing mTOR inhibitors with antivirals or immune modulators may provide synergistic benefits.

Despite these inherent advantages, early applications of ORFV-based technologies were limited by challenges in manufacturing scalability and uncertainties regarding clinical safety in humans. However, recent breakthroughs have transformed this therapeutic landscape. A landmark achievement is the development of Prime-2-CoV, an ORFV-based anti-COVID-19 vaccine that has advanced into human clinical trials, providing the first clinical evidence of live ORFV's feasibility, safety and immunogenicity. This milestone, together with the establishment of a good manufacturing practice (GMP)-compliant production process and comprehensive preclinical evaluations, has laid a robust foundation for broader clinical applications of ORFV-based therapeutics. Moreover, the use of ORFV as an oncolytic virus therapy has shown promising results, effectively converting immunologically 'cold' tumours into 'hot' ones, underscoring its versatility as a therapeutic platform. In this review, we critically assess recent advances in ORFV-based therapeutics, with a particular focus on vaccine development and oncolytic virotherapy (OVT). We thoroughly discuss the milestones and impact of the first ORFV-based clinical trial, outline strategies for optimizing the technology and provide insights into overcoming remaining challenges. Collectively, these advancements position ORFV as a highly promising and versatile platform for next-generation prophylactic and therapeutic interventions in both human and veterinary medicine, while also providing a roadmap for future innovations.</p>","PeriodicalId":21180,"journal":{"name":"Reviews in Medical Virology","volume":"35 3","pages":"e70038"},"PeriodicalIF":9.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12064845/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144012331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The clinical manifestations associated with these viruses range from self-limiting infections to life-threatening disorders. As a group of systemic viral infections, arboviruses can affect various parts of human organ systems, such as the nervous system. In the nervous system, epigenetic mechanisms are involved in various mechanisms including adult neurogenesis, neuronal-glial differentiation, the regulation of neural behaviour and neural plasticity, as well as other brain functions such as memory, and cognition. Hence, epigenetic deregulation is a key factor in the aetiology of different neurological disorders that highlights the importance of studying the underlying mechanisms and risk factors to introduce effective therapeutic approaches. There is mounting evidence that arboviruses that affect the nervous system take advantage of various mechanisms to modulate epigenetic processes to regulate their life cycles. This phenomenon may affect the nervous system leading to neurotropic arboviral infection-associated neurological disorders. Hence, it is important to understand reciprocal interplays between neurotropic arboviral pathogens and epigenetic processes to better control these disorders. The present review provides an overview of different interactions of arboviruses with epigenetic mechanisms during neurotropic arboviral infections. It uniquely focuses on the interplay between epigenetic modifications and arboviral neurotropism, shedding light on potential therapeutic strategies that have not been comprehensively addressed before. Targeting virus-induced epigenetic alterations, such as miRNA regulation, could lead to novel antiviral therapies aimed at mitigating neuroinflammation and disease severity.</p>","PeriodicalId":21180,"journal":{"name":"Reviews in Medical Virology","volume":"35 3","pages":"e70033"},"PeriodicalIF":9.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143743082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The absence of specific antiviral treatments and licenced human vaccines underscores the importance of understanding WNV pathogenesis, particularly the mechanisms by which it evades host immune responses. This review comprehensively analyzes the multifaceted immune evasion strategies employed by WNV, encompassing the suppression of interferon (IFN) production and signalling through targeting of STAT proteins, IRF3, and RNA sensors, the modulation of antigen presentation via downregulation of MHC molecules and impairment of proteasome function, and the manipulation of cytokine and chemokine responses to dysregulate inflammation and promote viral persistence. Furthermore, WNV exploits the blood-brain barrier (BBB) to gain access to the central nervous system (CNS), both by disrupting the barrier integrity and utilising \"Trojan horse\" mechanisms. The potential for antibody-dependent enhancement (ADE) further complicates the host-virus interaction. Understanding these immune evasion mechanisms is crucial for deciphering WNV pathogenesis and informing the development of effective vaccines and targeted immunotherapies aimed at preventing and treating WNV-related diseases. Future research should focus on translating this knowledge into tangible clinical benefits for at-risk populations, particularly regarding strategies to induce broadly neutralising antibody responses and robust T-cell immunity while mitigating the risk of ADE.</p>","PeriodicalId":21180,"journal":{"name":"Reviews in Medical Virology","volume":"35 3","pages":"e70042"},"PeriodicalIF":9.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144161760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inflammation plays a role of antiviral response as well as development of lethal encephalitis. Infection through a mosquito bite is biphasic, beginning with an inflammatory process and viral replication in different organs with subsequent infiltration to the central nervous system (CNS), inducing encephalitis. The direct route is through inhalation of aerosols containing the virus with direct brain infection through the olfactory nerve. Significant damage is due to exacerbated inflammation in the host. Angiotensin II (Ang II) is a molecule with high pro-inflammatory capacity, which has been found to be upregulated in the brain of VEEV-infected rats, suggesting its role in the pathogenesis of this disease. Limited information regarding the association of Ang II expression with VEEV brain infection has been reported. The aim of this review is to highlight published reports indicating a possible association between Ang II expression and VEEV-induced encephalitis. Several studies reflect a possible expression and function of Ang II during VEEV infection. Factors such as the relationship of Ang II with proteins involved in viral replication and entry into the cell (furin, Rab5, Rab7), activation of protein kinase C (necessary for the phosphorylation of VEEV), presence of microRNAs related to viral biology, increased permeability of the blood-brain barrier, and use of transcription pathways common to Ang II and VEEV, may conceivable an association of Ang II with the pathogenesis of VEEV encephalitis.</p>","PeriodicalId":21180,"journal":{"name":"Reviews in Medical Virology","volume":"35 3","pages":"e70040"},"PeriodicalIF":9.0,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144046292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Beyond their characteristic clinical presentations, emerging viruses, such as monkeypox virus (MPXV) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), have been increasingly implicated in the development of various neuropsychiatric complications including depression, mainly due to their ability to induce neuroinflammation, immune dysfunction, and neurotransmitter imbalances. Depression is a common mental health condition characterised by continuous low mood or sadness, pessimism, anxiety, and even a tendency to suicide as the main symptoms. Post viral depression commonly shows significant challenges, as traditional antidepressant agents exhibit suboptimal efficacy and prolonged onset of action. Regarding this, ketamine and its enantiomers, S-ketamine and R-ketamine, have recently received increasing attention as potential options in light of their potent and effective antidepressant properties. The present review describes the underlying pathophysiological mechanisms of depression associated with emerging viruses, highlighting the role of neuroinflammation and disturbances inneurotransmitter systems. It also discusses the antidepressant mechanisms of ketamine and its enantiomers, the current clinical evidence demonstrating their effectiveness and safety, especially in the case of treatment-resistant depression, and their growing relevance for mood complications linked to emerging viral infections, including depression. Although preliminary reports propose effectiveness, additional studies are needed to present optimal treatment strategies, long-term safety, and incorporation into clinical practice.
