Deriving Immune Modulating Drugs from Viruses-A New Class of Biologics

Area of Science:

• Virology
• Immunology
• Biotechnology

Background:

• Viruses are established platforms for therapeutics like vaccines and gene therapy vectors.
• The potential of virus-derived proteins as immune modulators is largely untapped.
• Viruses possess highly evolved, potent immune evasion mechanisms developed over millions of years.

Purpose of the Study:

• To review the current development of virus-derived immune-modulating biologics.
• To highlight the therapeutic potential of viral proteins targeting immunological pathways.
• To focus on immune modulators derived from poxviruses and herpesviruses.

Main Methods:

• Literature review of pre-clinical and clinical studies.
• Identification and analysis of virus-derived proteins with immune-modulating functions.
• Focus on specific viral protein families including serpins, chemokine modulators, and cytokine mimics/inhibitors.

Main Results:

• Numerous virus-derived proteins targeting key immune pathways have been identified.
• Examples include viral vascular endothelial growth factor and viral interleukin 10 mimics/inhibitors.
• Efficacy of these biologics has been demonstrated in pre-clinical and clinical settings.

Conclusions:

• Virus-derived proteins represent a promising, natural source for developing potent immune modulators.
• These biologics offer a novel therapeutic avenue, analogous to the discovery of penicillin.
• Further development, particularly from pox- and herpesviruses, holds significant therapeutic potential.
