A Scientific Breakthrough in Immune Health Ingredients

In the 1990s scientists discovered a rare subset of immune cells called plasmacytoid dendritic cells (pDCs) that act as leaders of the immune system. Once activated, pDCs recruit, organize and direct an army of pivotal immune cells involved in immune defense.

While the majority of immune activating supplements mainly target natural killer (NK) cells, researchers at Kirin knew that if they could find a novel dietary supplement and food ingredient that safely and effectively stimulates pDCs, they could develop an innovative immune health product that offers more comprehensive immune support than what has traditionally been available.

After testing more than a hundred strains of lactic acid bacteria, they finally found one strain that stood above the rest, LC-Plasma, which directly activated pDCs leading to the production of interferons.

Cultured using Kirin's proprietary technology, the unique strain was then heat-treated, making it nonviable and easier to both store and formulate for versatile application. LC-Plasma was then branded IMMUSE®, a novel postbiotic for proactive, system-wide immune support.

The First Lactic Acid Bacteria Shown to Activate pDCs for More Comprehensive Immune Support

Activated pDCs emit interferons (IFN-a), an important signaling molecule critical for systems-wide immune defense. LC-Plasma was shown to increase the production of IFN-a, while hundreds of conventional bacteria strains had minimal to no impact on pDCs.
