Summary

Human herpesviruses establish unique relationships with the central nervous system, causing illnesses through direct effects, immune responses, or cancer. This review covers latency, neuroinflammatory diseases, and new diagnostics and treatments for these viral infections.

Area of Science:

  • Neurovirology
  • Immunology
  • Infectious Diseases

Background:

  • Human herpesviruses exhibit a specialized tropism for the central nervous system (CNS).
  • Understanding the interplay between herpesviruses and the CNS is crucial for managing neurological disorders.

Purpose of the Study:

  • To review recent advancements in the mechanisms of herpesvirus latency in the CNS.
  • To discuss diverse neuropathologies arising from viral cytopathic effects, immune activation, and oncogenesis.
  • To highlight herpesvirus implications in acquired immunodeficiency syndrome (AIDS) and neonatal infections, alongside novel diagnostic and therapeutic strategies.

Main Methods:

  • Literature review of recent scientific publications.
  • Synthesis of data on viral latency, pathogenesis, and clinical manifestations.

  • Analysis of emerging diagnostic tools and treatment modalities.
  • Main Results:

    • Herpesviruses establish persistent infections in the CNS through various latency mechanisms.
    • Neurological diseases result from direct viral damage, immune-mediated inflammation, and virus-associated malignancies.
    • Herpesvirus infections pose significant risks in immunocompromised individuals (e.g., AIDS patients) and neonates.
    • Advancements in diagnostics and treatments offer improved management options.

    Conclusions:

    • Herpesvirus infections of the CNS are complex, involving intricate viral-CNS interactions.
    • Continued research into latency, pathogenesis, and host responses is essential.
    • Novel diagnostic and therapeutic approaches are improving patient outcomes for these challenging infections.
