Recombinant Immunoglobulin A (IgA) production for therapies faces challenges in large-scale manufacturing. This review details advancements and hurdles in producing and purifying IgA for therapeutic applications.
Area of Science:
- Biotechnology
- Immunology
- Biopharmaceutical Manufacturing
Background:
- Immunoglobulin A (IgA) is crucial for mucosal immunity and shows therapeutic promise for infectious and malignant diseases.
- Therapeutic development of IgA is hindered by challenges in producing and purifying sufficient quantities for research and clinical use.
Purpose of the Study:
- To review current biotechnological achievements and bottlenecks in the upstream and downstream processing of recombinant IgA.
- To highlight diverse expression systems and compare affinity techniques for recombinant IgA purification.
Main Methods:
- Review of current literature on recombinant IgA production.
- Analysis of upstream (expression) and downstream (purification) processing strategies.
- Comparison of various affinity chromatography techniques for IgA capture.
Main Results:
- Identified key challenges in large-scale recombinant IgA production and purification.
- Highlighted progress in diverse expression systems for IgA.
- Evaluated the purification potential of different affinity techniques for recombinant IgA.
Conclusions:
- Overcoming production and purification challenges is essential for realizing the therapeutic potential of IgA.
- Advancements in expression systems and purification technologies are critical for enabling IgA-based therapies.
- Further optimization of recombinant IgA manufacturing processes is required for in vivo studies and clinical applications.
