Definitions
- the present invention relates to a method for screening a diet that produces milk having an immunomodulatory action, and is useful in the food and feed fields.
- Living body immunity functions by nature as a “defense” against attacks from outside. For example, defense against infection or removal of cancer cells is “protection”, and in this case, enhancement of immunity effectively acts. On the other hand, an excessive reaction due to immunity, that is, “enhancement” may adversely affect the living body. Examples include allergic reactions, autoimmune diseases, chronic inflammation and the like. In this case, it is known that symptom improvement is observed by suppressing the production of inflammatory cytokines such as IL-6, TNF- ⁇ , and IL-1.
- microRNA microRNA
- miRNA After miRNA is transcribed from the genome, it is cleaved twice and becomes about 22 base untranslated small RNA. As its function, it is known to bind to the 3 ′ untranslated region of the target mRNA in a complementary manner and suppress the translation of the target mRNA.
- One type of miRNA controls various functions of cells by inhibiting translation of multiple mRNAs in the cell. In particular, there have been many reports on the occurrence and progression of cancer, and the relationship between miRNA and disease has attracted attention.

- Non-patent Document 16 miRNA that works intracellularly as a translation control molecule exists in a lipid bilayer called exosome and is secreted extracellularly. Since it was confirmed that the secreted miRNA was taken up by other cells, the existence of cell-cell interaction via miRNA was suggested. On the other hand, exosomes are known to exist in various human body fluids. In particular, the presence of miRNA has already been reported in human plasma and serum, suggesting the possibility of being used as a biomarker in prostate cancer and uterine cancer (Non-patent Document 17).
- Physiological fluids containing exosomes include saliva, urine, amniotic fluid and breast milk in addition to plasma and serum (Non-patent Document 17).

- the present invention provides a new finding that miRNA is contained in milk, that this miRNA can be stably present even under acidic conditions in the stomach, and that breast milk immunizes the infant who took it.
- This is based on the idea that an immunomodulatory action can be expected by oral administration of miRNA from the fact that it promotes (for example, Breastfeed. Med, 2 (4): 195-204, 2007).
- the miRNA profile in milk is based on the prediction that it will be affected by the diet, to identify the diet that can increase or decrease the abundance of miRNA in milk or the active ingredients contained in it. I came up with it.
- the immunomodulatory action defined by the screening method of the present invention, milk or dairy product, etc. is an action that enhances an immunostimulatory action that functions for the purpose of “protection” against an attack from the outside (immunity enhancing action), and Excessive reactions due to immunity, ie, “enhancement”, can be exemplified by allergic reactions that adversely affect the living body, immunosuppressive effects that function in a suppressive manner against autoimmune diseases, chronic inflammation, and the like.
- immunosuppressive action and “immunosuppressive action” are relative terms, and when the animal ingests the food or substance, compared to the immunostimulatory action normally possessed by the milk of a mammal. If the action is enhanced, the breast milk has an immune enhancing action, and if it is reduced, the breast milk has an immunosuppressive action. In addition, if the action is enhanced after ingestion, the breast milk of the animal has an immunopotentiating action, and if it is reduced, the mammal has an immunosuppressive action. .
- the correlation between the miRNA profile in the milk of a mammal and the diet ingested by the mammal or a substance contained in the diet can be examined, for example, as follows.
- Milk is collected from a mammal ingested and the miRNA profile in the milk is examined.
- Mammals are not particularly limited, and examples include humans, cows, goats, sheep, pigs, monkeys, dogs, cats, rats, mice, hamsters, guinea pigs and the like. Preferred are humans and cows.

- Bifidobacterium Bifidobacterium longum
- the abundance of 52 types of miRNAs increased.
- Bifidobacteria have a probiotic function, and are particularly known to have an immunomodulatory action. Therefore, the fact that the abundance of miRNA in milk was increased by administration of bifidobacteria also supports that miRNA in milk is involved in immune regulation.
- the increase in the amount of miRNA present in milk by bifidobacteria administration that is, the correlation between the bifidobacteria and the miRNA profile, indicates that the screening method of the present invention can be carried out.
- miRNAs whose abundance in milk was not changed by administration of bifidobacteria, but the possibility that the abundance of these miRNAs is increased by other diets or substances contained therein is not denied.
- Probiotic functions of bifidobacteria include respiratory tract infection, acute infectious diarrhea, antibacterial drug-related diarrhea, Clostridium difficile-related diarrhea, necrotizing enterocolitis, traveler diarrhea, and Helicobacter pylori infection Prevention or remission of diseases etc. is known (The Jounal of Nutirition, 2010 Mar; 140 (3): 698S-712S. Epub 2010 Jan 27.). It is suggested that miRNAs whose abundance in milk is increased by administration of bifidobacteria exhibit not only immune regulation but also functions similar to the above-mentioned probiotic functions in animals that ingest them.
- Milk having an immunopotentiating action or an immunopotentiating action is obtained by feeding a mammal a diet or substance that increases the abundance of miRNA in milk selected as described above and collecting milk from the animal. Increased milk is obtained. In addition, by reducing or avoiding the intake of mammals by a diet or substance that reduces the abundance of miRNA in milk selected as described above, the immune enhancement effect of milk is increased, or Decline can be prevented.

- the dairy product is not particularly limited as long as miRNA can exist while maintaining its function, and examples thereof include processed milk, prepared milk, milk beverage, prepared milk powder, fermented milk, cream, butter, cheese, and ice cream.
- dairy products dairy products for infants or infants are preferred.
- miRNAs particularly miRNAs known to be involved in immune enhancement such as immune development, antiallergy, anti-inflammation, infection protection, etc. are present in milk.
- breast milk has an immune enhancing effect on infants who take it. Therefore, it is reasonably expected that miRNAs involved in immune regulation can regulate the immunity of animals such as humans taken orally. Since miRNA is a substance that regulates the expression of various genes, the significance of transferring such regulatory molecules from the mother to the infant is considered to be very significant, especially for infants with an underdeveloped immune mechanism.
- Another embodiment of the present invention is a composition for oral intake having an immunopotentiating action, in which miRNA is added to the composition base for oral intake.

And the like, or these powdered milk), powder added to breast milk or prepared milk powder, baby food, and the like.
- formula milk is a food produced by using milk or dairy products as the main ingredient and added with nutrients necessary for infants and infants, and is mainly used as a substitute for breast milk in the infancy. In the early childhood, it is used as a food that plays a complementary role in breast milk replacement or nutrition intake, and for the purpose of contributing to nutrition intake suitable for infants with certain congenital or acquired diseases.
- the food to be manufactured is exemplified.
- MiRNA is relatively resistant to freezing and thawing, low pH, acidic conditions such as pH 1 and RNases such as RNase A and RNase T, and is suitable as an active ingredient added to foods.
- the stability at low pH suggests that miRNA molecules are resistant to the infant's gastric environment and can be absorbed by the intestinal tract, one of the baby's major immune organs. Can have an effect.
- storage, freezing and thawing of breast milk do not denature the miRNA, which is nutritionally important for low birth weight infants and hospitalized infants who are usually fed cryopreserved breast milk.
- the resistance to RNase suggests that miRNAs may be present in complexes such as exosomes and microvesicles in breast milk.
- breast milk-derived exosomes increase the number of Foxp3 + CD4 + CD25 + regulatory T cells. If immune-related miRNA is contained in breast milk exosomes, it may contribute to an increase in Foxp3 + CD4 + CD25 + regulatory T cells in the infant gastrointestinal tract. This is because immune-related miRNAs detected in breast milk such as miR-181a and miR-181b are highly expressed and are involved in T cell differentiation. Furthermore, miR-181 and miR-155 that were abundantly contained in breast milk were known to induce B cell differentiation, and miR-150 that suppresses B cell differentiation was hardly found in breast milk. Thus, miRNA in breast milk may induce B cell differentiation.

- Double-stranded DNA can be prepared by amplifying by PCR using a mammalian chromosomal DNA as a template and a primer designed to amplify the miRNA sequence.
- MiRNA is obtained by cleaving the double-stranded RNA obtained as described above with a Dicer enzyme or the like.
- MiRNA can also be produced by chemical synthesis. That is, miRNA is obtained by synthesizing a sense strand and an antisense strand and annealing them.
