Catalytic antibodies: balancing between Dr. Jekyll and Mr. Hyde

Area of Science:

• Biochemistry
• Immunology
• Biotechnology

Background:

• Immunoglobulin molecules serve as templates for generating biocatalytic functions.
• Catalytic antibodies (abzymes) mimic enzyme active sites to catalyze chemical reactions, including those lacking natural enzyme analogs.

Purpose of the Study:

• To explore the potential of abzymes as novel biocatalysts and therapeutic agents.
• To examine the dual beneficial and pathogenic roles of natural abzymes in autoimmune diseases.

Main Methods:

• Structural mimicking of enzyme active sites to generate catalytic antibodies.
• Investigating abzyme catalysis for reactions without natural enzyme counterparts.
• Analyzing the roles of naturally occurring abzymes in disease pathogenesis.

Main Results:

• Abzymes have demonstrated the ability to catalyze a wide range of chemical reactions.
• Advances in antibody engineering have expanded the medical applications of immunoglobulins.
• Natural abzymes exhibit both protective and destructive roles in autoimmune disease progression.

Conclusions:

• Abzymes represent a promising source for developing high-precision "catalytic vaccines."
• The development of therapeutic abzyme applications must account for their dual nature.
• Further research is needed to harness the full potential of abzymes while mitigating risks.
