Graphical summary of the immune shield system
The “Immune-Shield” is utilized through a twig methodology. This system stably coats even moist organ surfaces, and the microgels stay on the floor to slowly launch the immunosuppressant. By forming an invisible protecting layer on the organ, the system ensures the drug is delivered particularly to the transplant web site as an alternative of spreading by means of the bloodstream to the remainder of the physique.
In xenotransplantation experiments, the appliance of the “Immune-Shield” considerably lowered immune cell infiltration and inflammatory responses, considerably extending the survival of transplanted tissues. This discovering is important in that it demonstrated that an immunosuppressive impact was greater than twofold increased than that of typical drug supply strategies.
Professor Hyung Joon Cha, who led the analysis, acknowledged, “We propose a strategy to solve the long-standing challenge of immunosuppressants by using mussel adhesive protein, an original biomaterial developed in Korea.” He added, “Since the spray method allows for easy application to complex organ surfaces, it is expected to serve as a key technology to increase the success rate in the field of xenograft transplantation in the future.”
This analysis was supported by the Creative Innovation Program funded by POSCO Holdings and the Mid-career Researcher Program of the National Research Foundation of Korea, funded by the Ministry of Science and ICT.
