AI Article Synopsis

  • The extracellular space (ECS) serves as a protective barrier against viral infections in brain cells, with its microstructure dynamically influencing the progression of viral encephalitis and the effectiveness of antiviral treatments.
  • A new method combining single-particle diffusional fingerprinting of quantum dots and machine learning has been developed to analyze the ECS's characteristics during viral encephalitis.
  • This innovative approach allows for the characterization of ECS microrheology and geometry at various infection stages and can identify changes from drug treatments, paving the way for improved drug assessment and clinical applications.

Article Abstract

The extracellular space (ECS) is an important barrier against viral attack on brain cells, and dynamic changes in ECS microstructure characteristics are closely related to the progression of viral encephalitis in the brain and the efficacy of antiviral drugs. However, mapping the precise morphological and rheological features of the ECS in viral encephalitis is still challenging so far. Here, a robust approach is developed using single-particle diffusional fingerprinting of quantum dots combined with machine learning to map ECS features in the brain and predict the efficacy of antiviral encephalitis drugs. These results demonstrated that this approach can characterize the microrheology and geometry of the brain ECS at different stages of viral infection and identify subtle changes induced by different drug treatments. This approach provides a potential platform for drug proficiency assessment and is expected to offer a reliable basis for the clinical translation of drugs.

Introduction: Powassan virus (POWV), a vector-borne pathogen transmitted by ticks in North America, is the causative agent of Powassan encephalitis. As obligate hematophagous organisms, ticks transmit pathogens like POWV at the tick bite site, specifically during the initial stages of feeding. Tick feeding and salivary factors modulate the host's immunological responses, facilitating blood feeding and pathogen transmission.

Background: Neurological manifestations associated with COVID-19 remain partially described, mainly in low- and middle-income countries where diagnostic tools are limited. To address this, we assembled medical centers in Brazil with the goal of describing neurological syndromes associated with COVID-19 during the first wave of the pandemic.

Methods: From June 1st, 2020 to June 1st, 2021, non-consecutive adult patients with new onset of six neurological syndromes up to 60 days after confirmed COVID-19 were included.

Background: The Japanese encephalitis virus (JEV), a mosquito-borne flavivirus, is known for its capacity to cause severe neurological disease in Asia. Neurotropic flaviviruses within the Japanese encephalitis (JE) serogroup possess the distinctive feature of expressing a unique nonstructural protein, NS1'. The NS1' protein consists of the full NS1 protein with an additional 52 amino acid extension at the C-terminus and has been demonstrated to exhibit virulence in mammalian hosts upon infection.

The determinants of varicella-zoster virus (VZV)-associated central nervous system (CNS) infection have not been fully elucidated. This study aimed to investigate the incidence and risk factors, including immunosuppression, for different manifestations of VZV-associated CNS infection. Patient registers were used to include adults diagnosed with VZV-associated CNS infections between 2010 and 2019 in Sweden.

Seadornavirus is a genus of mosquito-borne viruses that includes Banna virus, which was first discovered in human patients with encephalitis and fever, as well as Kadipiro virus and Liao ning virus. In this study, we used metagenomics to investigate the diversity of viruses in wild ducks and detected both Banna virus and Kadipiro virus in wild birds in Siberia. These data suggest that seadornaviruses, which were previously only found in South East Asia, are also circulating in Northern Eurasia.
