Interferon stabilization and enhancement by rare earth salts.
The Journal of General Virology
|January 1, 1981
Summary
Rare earth element salts, specifically lanthanides, significantly boost interferon activity. These lanthanide salts also stabilize human fibroblast interferon against heat and mechanical stress.
Area of Science:
- Biochemistry
- Immunology
- Materials Science
Background:
- Interferons are crucial proteins in the immune response.
- Maintaining interferon activity is vital for therapeutic applications.
- Rare earth elements (lanthanides) have unique chemical properties.
Purpose of the Study:
- To investigate the effect of lanthanide salts on interferon activity.
- To determine if lanthanides can enhance and stabilize interferons.
- To assess the impact of lanthanides on human and mouse interferons.
Main Methods:
- Treatment of interferons with various lanthanide salts.
- Assay of interferon activity before and after lanthanide addition.
- Exposure of treated interferons to thermal and mechanical stress.
Main Results:
- Lanthanide salts increased the initial activity of human fibroblast, leukocyte, immune interferons, and mouse L-cell interferon by at least twofold.
- Lanthanides preserved human fibroblast interferon activity after 4 days at 37°C.
- Significant stabilization of human leukocyte interferon was also observed, though to a lesser extent.
Conclusions:
- Lanthanides enhance the biological activity of multiple interferon types.
- Lanthanide salts offer a stabilizing effect on interferons, improving their resilience.
- These findings suggest potential applications for lanthanides in interferon-based therapies.
