Plant-origin nano-sized lactic acid bacterium SNK

About plant-origin nano-sized lactic acid bacterium SNK® (Patented)
SNK is the powdered Lactbacillus Plantarum

The plant-based nano-type lactic acid bacterium SNK is the powdered lactic acid bacteria (Lactbacillus Plantarum) (sterilized) derived from the traditional food "sunki pickle" in the Kiso region in Nagano Prefecture which is processed the size to less than 1 micron using our proprietary technology to increase the utilization efficiency in the body. It particularly shows superior performance in adjusting the immunological balance of the body.

Morbidity of allergic diseases

Nagano Prefecture is well known as a prefecture where people live long. In addition, the morbidity of allergic diseases in Nagano Prefecture is much lower than the national average; it is extremely low in the Kiso region in particular which is revealed to be approximately one third of that in Nagano Prefecture by epidemiological study.

Sunki-pickles, which have traditionally been made for more than 400 years in the Kiso-region of Nagano Prefecture, are simply produced by lactic acid fermentation of the leaves of red turnips without salt, which is a rare method of producing pickles anywhere in Japan.

SNK made from Sunki-pickles

In the Kiso region, epidemiological research also revealed that many people have a healthy immunological balance. The reason for this phenomenon is thought to be the lactic acid bacteria derived from Sunki-pickles.

What is nano-sized lactic acid bacterium?

Nano-sized lactic acid bacteria is sterilized lactic acid bacteria with a particle size of less than 1 micron, and disperse when dissolved in water.

From the results of many years of research, it has become clear that regardless of the life and death of lactic acid bacteria its "particle" works on various immune cells in the immune system of the intestine.

So that lactic acid bacteria is expected to work not only for intestinal regulation but also various things such as immunomodulation and aging prevention. In particular, small particle lactic acid bacteria is efficiently absorbed in the intestine, thereby activates immune cells, creates intracellular mediators, and enhances immunity.

<Unbalanced immunological system in modern people>

In the small intestine, approximately 60% of the immune cells in the entire body are gathered and the health of one’s body is supported by maintaining a balance between Th1 and Th2 cells, which is the essential components of the immune system.

However, people living in the modern world often tend to disrupt this immunological balance favoring Th2 cells, because of a disturbance of the autonomic nervous system, lifestyle changes, and/or aging.

SNK controls our immunity balance

Nano-sized lactic acid bacteria made by separating adhesion of lactic acid bacteria and dispersing them, can easily pass through Peyer’s patches in the small intestine. This production method can induce Th1 cells and adjust the immunological balance between Th1 and Th2 cells.

<Evaluation of IL-12 production inducing activity (in vitro)>

When the plant-origin nano-sized lactic acid bacterium SNK and OK432* were compared, the activities were found to be at the same level.

*OK432: Immunotherapeutic agent to increase the immunity of the human body.

SNK increased IL12

(Measurement method)

•Method of measurement for IL-12 production inducing activity

•Using BALB/c mouse: 23 weeks of age

•The concentration of samples at the time of measurement: 10 μg/mL after converting to cell weight

<Inhibition of Th17 cell production (Peyer’s patch of mouse ileum)>

With the continuous use of the plant-origin nano-sized lactic acid bacterium SNK, the behavior of the immune system cells developing intestinal problems such as colitis was studied.

As a result, a significant dose-dependent inhibition of SNK in the production of Th17 cells, which is relates autoimmune diseases, was observed.

(Test Method)

30 mice were divided into 3 groups of 10 mice (C: only physiological saline solution, L: physiological saline solution + SNK 2mg/kg, H: physiological saline solution + SNK 10mg/kg) and were administered for 15 days. After oral administration for 10 days, dextran sodium sulfate, which induces colitis, was injected to cause inflammation. After dissecting 16 days after administration, analyses for each group were conducted to determine the ratios of Th17 cells and the gene expressions of transcription factor that are related to Th17 cells.
