Enzyme loading of erythrocytes.

G M Ihler, R H Glew, F W Schnure

    Proceedings of the National Academy of Sciences of the United States of America
    |September 1, 1973
    PubMed
    Summary

    Researchers can trap enzymes like beta-glucosidase inside red blood cells (erythrocytes) using rapid hemolysis. This method allows for efficient enzyme uptake, potentially aiding enzyme replacement therapy for genetic diseases.

    Area of Science:

    • Biochemistry
    • Cell Biology
    • Enzyme Kinetics

    Background:

    • Enzyme replacement therapy is crucial for treating certain genetic disorders.
    • Efficiently delivering enzymes into target cells remains a challenge.

    Purpose of the Study:

    • To investigate a novel method for entrapping enzymes within erythrocytes.
    • To assess the feasibility of using hemolysis for enzyme uptake.

    Main Methods:

    • Erythrocytes were subjected to rapid hemolysis in the presence of beta-glucosidase and beta-galactosidase.
    • Enzyme uptake efficiency and cell integrity were analyzed post-hemolysis.

    Main Results:

    • Enzymes were successfully trapped within erythrocytes during rapid hemolysis.
    • Optimal enzyme uptake occurred within 60 seconds.
    • Entrapped enzymes showed minimal impact on erythrocyte count and mean cell volume.
    • Proteins up to 180,000 molecular weight were effectively entrapped.

    Conclusions:

    • Rapid hemolysis is an effective method for entrapping enzymes in erythrocytes.
    • This technique offers a promising approach for enzyme replacement therapy in diseases like Gaucher's disease.
