Immunological Control of Herpes Simplex Virus Type 1 Infection: A Non-Thermal Plasma-Based Approach.

Area of Science:

• Virology
• Immunology
• Plasma Medicine

Background:

• Herpes simplex virus type 1 (HSV-1) establishes lifelong latency in trigeminal ganglia, causing recurrent cold sores.
• Current antiviral therapies cannot cure HSV-1, and vaccine development has been unsuccessful.
• The host immune system, particularly CD8+ T cells, controls HSV-1, but disruptions lead to reactivation.

Purpose of the Study:

• To investigate non-thermal plasma (NTP) as a potential therapy for recurrent HSV-1 infections.
• To evaluate the direct antiviral effects of NTP on HSV-1-infected cells.
• To explore NTP's potential to modulate immune responses for enhanced HSV-1 control.

Main Methods:

• Direct application of NTP to HSV-1-infected cells in vitro.
• Assessment of antiviral effects and cellular responses to NTP treatment.
• Proposed evaluation of indirect effects on viral latency and T cell responses.

Main Results:

• NTP demonstrated direct antiviral effects against HSV-1-infected cells.
• NTP treatment stimulated cellular stress and immunomodulatory responses.
• Preliminary findings suggest NTP could reduce viral seeding and enhance immune control.

Conclusions:

• NTP presents a novel therapeutic strategy for managing recurrent HSV-1 infections.
• NTP's direct antiviral and immunomodulatory actions may offer long-lasting control over HSV-1.
• Further research is warranted to explore NTP's clinical efficacy against HSV-1 latency and reactivation.
