Description

Burkholderia vietnamiensis strain and its use for improving hair or scalp condition}

It relates to novel microorganisms, their lysates, culture solutions, extracts, fermented solutions, and their use for improving hair or scalp conditions.

In the human body, hair grows from hair follicles on the scalp, and cycles of growth (anagen), catagen (catagen), and telogen (telogen) are continuously repeated throughout life and go through generation, growth, and shedding (Paus et al. , J Invest Dermatol. 113, pp.523-532, 1999). In the catagen phase of the hair follicle, the growth of the hair follicle is stopped, and apoptosis and reorganization of the extracellular matrix occur. Therefore, as the number of hair follicle cells in the catagen and telogen phases of the hair follicle increases, the hair falls out and does not grow back. .

Hair is divided into the visible hair shaft and the invisible hair root, and among the hair roots, the root from which hair grows is called the hair bulb, and the recessed part at the bottom is called the hair papilla (Fig. One). The dermal papilla is the most important part in the development of hair, and has blood vessels and nerves to deliver nutrients and growth factors to promote hair growth. Since the number of hairs decreases due to the death and growth reduction of dermal papilla cells, proliferation of dermal papilla cells is required to maintain and increase hair.

In addition, in the case of seborrheic scalpitis in which scalp lipids are excessively secreted, sebum secreted from the sebaceous glands of the hair follicles is increased by the action of androgen hormones, and the amount of microorganisms present on the scalp increases as the sebum increases. These scalp microorganisms can generate wastes on the scalp and cause hair loss symptoms accompanied by itching and pain (Journal of the Korean Society of Aesthetics, Vol. 18, No. 2 (2012), pp. 279-289).

Recently, as environmental pollution and urban stress become more serious, as the number of modern people with alopecia increases, interest in materials capable of improving them is increasing. Therefore, an attempt was made to invent a substance capable of strengthening the hair root and helping to prevent hair loss by inducing hair growth by increasing the expression of growth factors in the dermal papilla cells responsible for the start of hair production in the hair root. In addition, it was attempted to invent a substance that solves sebum-induced inflammation and itching by utilizing microbial cells and strain cultures that inhibit scalp lipids, and further prevents hair loss symptoms.

In this regard, Korean Patent Registration No. 10-2102578 discloses a cosmetic composition for promoting hair growth or hair growth containing a plurality of compounds. However, there are not many studies on microorganisms that can improve hair or scalp condition.

Probiotics is a collective term for microorganisms that have a beneficial effect on the human body, and refers to microorganisms that benefit the body. Most probiotics known to date are known as lactic acid bacteria. Probiotics have been reported to produce effective effects through various beneficial effects on the human body, but studies on the interaction between scalp flora and scalp are insufficient.

Therefore, it is necessary to develop a fungus on the scalp that can be usefully used for scalp-related conditions.

Example 1. Isolation and identification of strains

A sample was obtained by washing the scalp of a male in his twenties with a healthy scalp with sterile distilled water. The samples were inoculated into R2A (Reasoner's 2A) liquid medium or solid medium (manufacturer: Difco). After culturing in a 28° C. incubator for 48 hours after inoculation, 100 formed colonies were cultured in pure isolation and re-cultured in a 28° C. incubator for 48 hours. 16S rRNA sequence identification was performed on colonies completed with culture. The primers used at this time were designed to amplify in response only to bacteria. PCR amplification was carried out in 30 cycles of 95 ° C for 1 minute, 55 ° C for 1 minute, and 75 ° C for 1 minute and 30 seconds, and finally maintained at 72 ° C for 8 minutes and then stored at 4 ° C. After the PCR reaction, the DNA sequences of the isolated and cultured species were determined using ABI-3730XL (ABI, USA).

When the nucleotide sequence of the 16S rRNA region determined in the isolated and cultured microbial colony was compared and analyzed with other strains registered through the BLAST program provided on the homepage of the National Center for Biotechnology Information (NCBI), homology 97 Only novel species of less than % were selected, and among them, a novel microorganism Burkholderia vietnamiensis strain (hereinafter referred to as "SP-7") having 98% or less homology was selected. The selected SP-7 strain was deposited with the Korea Microorganism Conservation Center on October 28, 2020 and was given accession number KCCM12821P. The SP-7 strain has a 16S rRNA sequence of SEQ ID NO: 1 (complementary DNA).

Experimental Example 1. Evaluating the efficacy of increasing the proliferative capacity of human dermal papilla cells (HFDPC)

In order to evaluate whether the culture of the SP-7 strain isolated in Example 1 markedly induces the proliferation of dermal papilla cells, MTT (3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyl-2H-tetrazolium bromide) assay was performed.

First, human dermal papilla cells (HFDPC) were dispensed in 2x10 ⁴ cells/well in a 96-well plate, and then cultured for 24 hours in an incubator at 37°C and 5% CO ₂ conditions. Then, after replacing with a medium containing nothing, 1% (w / w) of the culture medium of the SP-7 strain was added and further cultured for 24 hours. A group containing 10 ppm of minoxidil (Minoxidil, MXD, 6-piperidin-1-ylpyrimidine-2,4-diamine 3-oxide), known as a hair growth promoter, was set as a positive control group instead of the strain culture medium, and a medium containing no strain culture medium The addition group (medium con) was set as a negative control group, and the culture medium addition group (None) was also set as a control group to confirm the efficacy of the strain culture medium. After 24 hours, the medium of each well was removed, washed once using DPBS (Dulbecco's phosphate buffered saline), and then 500μl of 0.5mg/mL MTT (Sigma-aldrich, St. Louis, USA) was added to each well. medium and reacted at 37°C for 4 hours. Then, absorbance was measured at 570 nm using Victor 3 (Perkin-Elmer). The cell viability was expressed as a percentage of the measured average absorbance value, and through this, the proliferative ability of human dermal papilla cells (HFDPC) can be confirmed.

As shown in Figure 2, it was confirmed that the strain of Example 1 exhibits an excellent dermal papilla cell proliferation effect.

Therefore, it was confirmed that the SP-7 strain can be used for strengthening hair roots, preventing hair loss, and promoting hair growth.

Experimental Example 2. Scalp lipid inhibition efficacy evaluation

In order to evaluate whether the culture solution of the SP-7 strain isolated in Example 1 inhibits scalp lipids, lipid inhibition was evaluated after inducing lipid peroxides into keratinocytes.

Specifically, after dispensing human keratinocytes (HaCaT) into a 6-well plate by 3x10 ⁵ cells/well, they were cultured for 24 hours under cell culture conditions. After 24 hours, the medium was discarded, washed with PBS, and peroxidated squalene was diluted to 1% (w/w) in a medium without FBS, and lipid peroxide was induced by adding it to the cells. Thereafter, 1% (w/w) of the culture medium of the SP-7 strain was added and further cultured for 72 hours. A medium 1% (w/w) addition group (media con, RCM control) not containing the strain culture medium was set as a negative control group. After discarding the medium and washing with PBS three times, Nile red O staining was performed to stain cell lipids. Nile red solution (1 mg/ml in acetone) diluted 1/1000 in a medium without FBS was added to the cells, and after 10 minutes, it was put into an IncucyteZoom (Essen BioScience) device and photographed with a fluorescence microscope, and fluorescence intensity was quantified. did

Figure 3 shows the effect of reducing the generation of lipids secreted from keratinocytes.

As shown in Figure 3, it was confirmed that the strain of Example 1 exhibits an excellent lipid inhibition effect.

Therefore, it was confirmed that the SP-7 strain can be used for suppressing scalp lipids, preventing dandruff, improving or suppressing scalp inflammation and itching caused by sebum, preventing hair loss due to lipid peroxides, and promoting scalp health.
