                    Introduction: Interleukin-2 (IL-2), a cytokine that drives the expansion of T cells and their phenotypic development, plays a crucial role in wound healing. The most studied function of IL-2 is its influence on T-cell growth. However, other cell types, such as fibroblasts and skin cells responsible for wound repair, also express the IL-2 receptor and may respond to IL-2. Studies have indicated that IL-2 treatment can enhance the strength of healed skin, highlighting its significance in the wound-healing process.
Methods: In this study, a microbial expression vector containing the coding sequence for IL-2 was optimized and transferred to a bacterial strain. The expression of the recombinant protein was analyzed post-induction using SDS-PAGE and Western blotting with specific antibodies. For purification, affinity chromatography was employed. The biological activity of the produced protein was assessed by plotting the growth curve of NIH-3T3 cells.
Results: After establishing an appropriate expression pathway, 8.01 mg of IL-2 was purified per liter of bacterial culture in an Erlenmeyer flask. The purified IL-2 exhibited suitable structure and biological activity.
Conclusion: The bacterial strain can produce recombinant IL-2 with proper folding. The produced recombinant IL-2 has biological activity, and the production method was scalable and economically viable.
