Whole-genome sequencing surveillance of Siberian tick-borne encephalitis virus (TBEV) identifies an additional lineage in Kyrgyzstan.

Tick-borne encephalitis virus (TBEV) is the most prevalent tick-borne viral disease in Europe and Asia. There are three main subtypes of the virus: European, Siberian, and Far Eastern, each of which having distinctive ecology, clinical presentation, and geographic distribution. In recent years, other TBEV subtypes have been described, namely the Himalayan and Baikalian subtypes.

Evaluating the need for standardised disease manifestation categories in patients infected with the tick-borne encephalitis virus: A Delphi panel.

Categorization systems for tick-borne encephalitis virus (TBEV) infection lack consistency in classifying disease severity. To evaluate the need for a standard, consensus-based categorisation system for TBEV infection across subtypes, we gathered an expert panel of clinicians and scientists with diverse expertise in TBEV infection. Consensus was sought using the Delphi technique, which consisted of 2 web-based survey questionnaires and a final, virtual, consensus-building exercise.

Differential diagnosis and comparison of diagnostic algorithms in children and adolescents with autoimmune encephalitis in Spain: a prospective cohort study and retrospective analysis.

Background: The usefulness of current diagnostic approaches in children with suspected autoimmune encephalitis is unknown. We aimed to assess the diagnosis of autoimmune encephalitis in clinical practice and to compare the performance of two international diagnostic algorithms (one intended for patients of any age [general], the other intended for paediatric patients), with particular emphasis on the evaluation of patients with probable antibody-negative autoimmune encephalitis because this diagnosis suggests that immunotherapy should be continued or escalated but is difficult to establish.

Methods: We did a prospective cohort study that included all patients (<18 years of age) with suspected autoimmune encephalitis recruited at 40 hospitals in Spain whose physicians provided clinical information every 6 months for 2 years or more.

Recent advances in autoimmune encephalitis.

Since the description of autoimmune encephalitis (AE) associated with N-methyl-D-aspartate receptor antibodies (anti-NMDARE) in 2007, more than 12 other clinical syndromes and antibodies have been reported. In this article, we review recent advances in pathophysiology, genetics, diagnosis pitfalls, and clinical phenotypes of AE associated with cell surface antibodies and anti-GAD associated neurological syndromes. Genetic studies reported human leukocyte antigen (HLA) associations for anti-LGI1, anti-Caspr2, anti-IgLON5, and anti-GAD.

Eilat virus isolated from Culex univittatus mosquitoes from the Namibian Zambezi Region influences in vitro superinfection with alpha- and flaviviruses in a virus-species-dependent manner.

The genus Alphavirus harbors arboviruses of great concern, such as the Chikungunya virus and the equine encephalitis viruses. Transmission of pathogenic alphaviruses by mosquitoes could be influenced by insect-specific alphaviruses such as Eilat virus (EILV). However, insect-specific alphaviruses are rarely found in wild mosquitoes and only a few have been described in the literature.

In response, states implemented targeted vaccination programs for those individuals at the highest risk of JEV exposure.

Testing perioperative meloxicam analgesia to enhance welfare while preserving model validity in an inflammation-induced seizure model.

Despite the international effort to improve laboratory animal welfare through the 3R principles (Reduce, Refine, Replace), many scientists still fail to implement and report their assessment of pain and well-being, likely due to concerns regarding the potential effects of analgesics on experimental outcomes. This study aimed to determine whether refining our viral encephalitis model with perioperative analgesia could enhance well-being and recovery after intracerebral virus infection without impacting disease outcomes. We routinely use the Theiler's Murine Encephalomyelitis Virus (TMEV) model to study virus-induced epilepsy.

Bickerstaff Brainstem Encephalitis (BBE) is a rare immunologic condition characterized by CNS inflammation, presenting with ataxia, external ophthalmoplegia, altered consciousness, and quadriplegia. A 25-year-old male with no significant medical history exhibited symptoms of blurred vision, diplopia, facial numbness, and imbalance following a respiratory infection. Brain MRI revealed hyperintense lesions in the cerebral peduncle and pons on T2-weighted/FLAIR sequences but not on T1-weighted sequences, indicative of demyelination.

Safety of talimogene laherparepvec: a real-world retrospective pharmacovigilance study based on FDA Adverse Event Reporting System (FAERS).

Background: Oncolytic virus therapy is a rapidly evolving emerging approach for the medical management of cancer. Talimogene laherparepvec (T-VEC) is the first and only Food and Drug Administration (FDA)-approved oncolytic virus therapy. Considering that exactly how T-VEC works is not known, there is a strong need for a comprehensive pharmacovigilance study to identify safety signals of potential risks with T-VEC.

Nucleotide-binding oligomerization domain 1 (NOD1) regulates microglial activation in pseudorabies virus infection.

The primary cause of viral encephalitis (VE) is invasion of the central nervous system (CNS) by the virus, which leads to neuroinflammation and poses a significant threat to global public health. Microglia, as CNS-resident macrophages, play a crucial role in neuroinflammation and are often identified as the preferred target for the prevention or treatment of VE. In this study, we used pseudorabies virus (PRV)-induced VE in mice and pigs as a model to investigate the regulation of microglial responses during viral encephalitis and explored the mechanism of microglial activation.
