Therapy of viral infections of the central nervous system

Area of Science:

• Neurovirology
• Infectious Diseases
• Pharmacology

Background:

• Current antiviral treatment guidelines for central nervous system (CNS) infections are primarily established for herpesviruses, notably herpes simplex virus (HSV).
• Emerging data suggest potential for specific antiviral therapies in Human Immunodeficiency Virus (HIV)-associated CNS disease, despite incomplete understanding of disease mechanisms.
• The development of antiviral drugs is accelerating, indicating a future where more CNS viral infections could be targeted.

Purpose of the Study:

• To review the current landscape of antiviral treatments for CNS viral infections.
• To highlight the challenges and future prospects for antiviral therapy in neurovirology.

Main Methods:

• Literature review of existing guidelines and emerging research on antiviral therapy for CNS infections.
• Analysis of factors limiting the efficacy of antiviral drugs in the CNS, such as drug penetration.

Main Results:

• Herpesviruses (HSV) represent the main group of CNS viral infections with established antiviral treatment protocols.
• Specific antiviral therapy for HIV-associated CNS disease is under investigation, but its pathogenesis is not fully elucidated.
• CNS penetration remains a significant hurdle for many antiviral compounds, limiting their application.

Conclusions:

• While antiviral drug development is progressing, successful treatment of a broader range of CNS viral infections is contingent on overcoming challenges like drug delivery to the CNS.
• Further research into the pathogenesis of CNS viral diseases and the development of CNS-penetrant antivirals is crucial.
