摘要:
This invention relates to the use of a preparation comprising sulfated oligosaccharides which trap spermine and/or spermidine, as an active slimming ingredient in a cosmetic, pharmaceutical and/or nutraceutical composition. One aspect of the invention is to supply a cosmetic, pharmaceutical or nutriceutical composition with a slimming effect.
摘要:
The invention concerns active substances modulating the expression of the receptors of the products of the POMC gene (MC-IR, MC-2R, and the μ opioid receptor), and possibly modulating the expression of POMC in cutaneous cells, notably to modulate the proliferation and differentiation of epidermal cells in order to re-epithelial, maintain innervation, irrigate the skin, or restore normal pigmentation, or to fight against aging, or to modulate pigmentation independently or not of cutaneous aging. The invention also concerns a method of screening such active substances.
摘要:
The invention relates to the use, as active ingredient, of at least one substance that promotes AGE deglycation, for the preparation of a composition, especially for limiting the presence of AGEs in a tissue. The invention relates in particular to the use of such a substance for the preparation of a composition for use in preventing and/or combating the decrease in flexibility and/or plasticity and/or elasticity and/or functionality of a tissue, and/or in preventing and/or combating ageing of a tissue, by promoting AGE deglycation in the tissue, wherein said tissue is preferably the skin, or the tissue wall of a blood vessel or of an organ.
摘要:
The present invention relates to the use of an active substance that promotes the inhibition of AGE formation, for the preparation of a composition for preventing and/or combating the decrease in elastic and plastic properties of tissues, and in particular of the skin, for inhibiting AGE formation, or for preventing and/or combating protein glycation at the cutaneous level. The invention also relates to a method of screening for such active substances.

The invention relates to a cell culture device. This cell culture device (100), intended for receiving cells with their culture medium, is characterised in that it contains at least one cell-supporting layer of porous material, this layer being obtained by dehydration of an aqueous gel which is poured directly either into said well bottom (110-111), or into the bottom of a cradle or insert (150) of a size which is adapted for being insertable into the volume of the well. The invention enables a culture to be made which can be automated.
摘要:
The present invention relates to a method for preparing Langerhans cells (LC), or dermal/interstitial dendritic cells (IDC) or LCs and IDCs from CD 14+ monocytes stemming from peripheral circulatory blood of a living being, and notably of a human being, comprising differentiation of CD 14+ monocytes into LCs, or into IDCs, or into LCs and IDCs by putting the CD 14+ monocytes in the presence of a cell environment comprising epithelial cells, such as keratinocytes, and/or mesenchymatous cells such as dermal fibroblasts. The present invention also relates to cell or tissue models comprising at least LCs and/or IDCs, and optionally macrophages and endothelial cells, able to be obtained according to this method, and to their uses.
