Inside-the-body immunoregulatory platform technology using the characteristics of γ-PGA, a new immunity-controlling material for medicine
Core source technology utilizing γ-PGA, which enhances the activation of natural killer cells by using a high-molecular substance created by a microorganism called "Bacillus subtilis" to stimulate immunocytes in the intestinal mucosal membrane.
New medicine development platform technology based on the immunoregulatory effects of a natural amino acid high-molecular refined substance, "γ-PGA (Poly-γ-glutamic Acid)"
A structure in which glutamic acid, a necessary type of amino acid, is repetitively connected through gamma-peptide bonds
Its mechanism is an immunoregulatory effect : TLR4 as a medium ① Induces innate immunity ② Strengthens adaptive immunity ③ Improves the tumor microenvironment (TEM) in a favorable manner
"Bacillus subtilis Chungkookjang," a GRAS (Generally recognized as safe) microorganism
Produced with a patented strain
Medicine under development and diseases to be treated
Extended application for more diseases : A combined treatment of tumor with Immune Checkpoint Blockade (ICB), cell therapy products, etc.
Poly-γ-glutamic acid (γ-PGA)
An edible amino acid, high-molecular material, and a natural substance found in bean-fermented foods such as Korea's very own "cheonggukjang"
Produced by Bacillus subtilis Chungkookjang, a type of GRAS (generally recognized as safe) microorganism with edible safety established (BioLeaders' patented strain)
Though it is a natural substance, a mass production system for γ-PGA of high molecular weight (2,000 kDa on average) has been established through a fermentation and refinement processes (certified as one of Korea's Top 10 New Technologies)
Increase in immunoreaction via γ-PGA, effective against cancer, viruses, and inflammation diseases
γ-PGA also has several health-related functions including moisturization, acceleration of mineral absorption, and inhibited activation of the lyase of hyaluronic acid, which is a tissue component inside the body
Oral administration
High Stability and ease of administration
Absorption in the small intestine via oral dosing
Activation of dendritic cells and dendritic cells, which are immune cells in the small intestine mucosa
Increased immune response by poly-gamma glutamic acid
Anticancer effect
antiviral effect
Inflammatory disease inhibitory effect
Innate immunity
γ-PGA enhances innate immune function through intestinal mucosa cells
Enhance immune function by activating immune cell (marcrophage) and natural killer cells (NK cells) that maintain immune function in vivo
Antigen-presenting cell activation
Adaptive immunity
increased immune response by inducing maturation of immature dendritic cells
