Definitions
- probiotic microorganisms as an agent promoting the synthesis of melanin
- the present invention relates to the oral use of the strain of Bifidobacterium longum deposited under the number 1-2618 with the CNCM to induce the pigmentation of the skin and hair, and homogenize the complexion.
- the color of human hair and skin is a function of various factors, such as seasons of the year, ethnicity, gender, and age. It is mainly determined by the concentration and distribution in keratinocytes of melanin produced by melanocytes.
- Melanin a natural pigment known for its anti-radical and absorbing properties of solar radiation, is a physiological protective agent of the skin, existing in two major forms: eumelanin and pheo-melanin.
- Melanocytes are the specialized cells that synthesize melanin and then distribute it to keratinocytes through particular organelles, melanosomes.
- the melanocyte In the epidermis, the melanocyte is involved in the epidermal melanic unit, forming a distribution network between melanocytes and keratinocytes, which consists of a melanocyte surrounded by about 36 neighboring keratinocytes.
- Melanocytes account for approximately 5 to 10% of basal layer cells of the epidermis. All individuals, regardless of phototype, have approximately the same number of melanocytes for a given skin area. Differences in pigmentation between individuals are not due to the number of melanocytes, but to the nature of the synthesized melanin and the biochemical and functional properties of melanosomes.
- Melanosomes are highly specialized organelles whose sole function is the synthesis and transfer of melanin. They arise from the endoplasmic reticulum in the form of spherical vacuoles called pre-melanosomes that contain an amorphous protein substrate, but no melanogenic enzymes. During the maturation of the pre-melanosome, the amorphous substrate is organized into a fibrillar structure oriented in the longitudinal axis of the melanosome. There are four stages of development of melanosome corresponding to the intensity of melanization. Melanin is uniformly deposited on the inner fibrillar network of the melanosome and the opacity of the organelle increases to saturation.
- melanosomes As melanosomes are synthesized in melanosomes, they move from the perinuclear region to the end of the melanocyte dendrites. By phagocytosis, the end of the dendrites is captured by keratinocytes, the membranes are degraded and the melanin content of the melanosomes is redistributed in the keratinocytes. The melanin is thus distributed in the epidermis, ensuring its browning and protection.
- the pigmentation of hair and hair requires the presence of melanocytes in the bulb of the hair follicle.
- the hair follicle is a tubular invagination of the epidermis that penetrates to the deep layers of the dermis.
- the inner part of the bulb is a zone of cellular proliferation where the precursors of the keratinized cells constituting the hair are found.
- the melanocytes in the bulb of the hair follicle are in an active state, that is, they synthesize melanin. These pigments are transmitted to the keratinocytes intended to form the hair shaft, which will lead to the growth of a pigmented hair or hair.
- the mechanisms leading to the pigmentation of the skin and keratinous fibers, especially hair and hair, are highly regulated mechanisms, under the influence of multiple hormonal or cellular factors.
- melanocytes finely regulated by these hormonal or cellular factors, makes it possible to confer on skin and keratin fibers a natural, homogeneous, more or less intense pigmentation, imparting an attractive aesthetic and cosmetic appearance.
- changes in the physiology of the epidermis and hair follicle can alter the pigmentation of the skin, hair and hair.
- these modifications may result in dysregulation of melanocyte homeostasis, manifested by disorders of proliferation, maturation or survival, possibly accompanied by an abnormality or an imbalance of the melanogenesis.
- compositions containing a phosphodiesterase inhibitor (WO 95/17161), prostaglandins (WO 95/1 1003), DNA fragments (WO 95/01773), DNA encoding MSH receptors (WO 94/04674), diacylglycerols (WO 94/04122), tyrosine derivatives (EP 0585018), ballot extracts (WO 93/10804), or xanthine extracts (WO 91/07945) .

- NHEM Primary human melanocytes
- NHEK normal human epidermal keratinocytes
- the cells were then treated with nothing (negative control), IBMX (positive control, 200 ⁇ l), a lysate or Bifidobacterium longum subsp. longum CNCM 1-2618 (1%), a comparative lysate from another strain of Bifidobacterium longum (Repair Complex CLR ® 1%), an extract from Propionibacterium freudenreichii (0.2%) or a Bacillus coagulans extract (2 mg / ml).
- the cells were incubated for 72 h, all experimental conditions having been performed in triplicate. After 72 hours of incubation, the cells were lysed with a 0.5 N NaOH solution in order to extract the melanin. The optical density of the samples was measured at 405 nm, with reference to an exogenous melanin range (standard melanin curve 0.39 to 100 ⁇ g / ml).
- results are expressed as a percentage of relative stimulation compared with the control grown in standard co-culture medium. They were analyzed with Student's statistical test:
- the inventors have thus shown that the incubation of NHEK / NHEM co-cultures with lysates of probiotic microorganisms made it possible to significantly increase melanin production by melanocytes compared with untreated cocultures (see FIG. .
- Example 2 Compositions according to the invention for the oral route
- One to three of these capsules can be taken daily.
