Photoprotective and cryoprotective effect of the carotenoid bacterioruberin on peripheral blood mononuclear cells

Key Points

• Bacterioruberin demonstrates significant photoprotection for peripheral blood mononuclear cells under oxidative stress conditions, reducing cell damage.
• Cryoprotection is also noted, enhancing cell viability during low-temperature exposure, which may improve cell preservation techniques.
• Analysis of cell responses reveals that bacterioruberin mitigates both oxidative stress and cold-induced cell damage effectively.
• These findings imply potential clinical applications for bacterioruberin in therapeutic and preservation settings, highlighting its protective properties.
