摘要:
The invention relates to a model of reconstructed cornea, which may be used especially in tissue engineering, to a biomaterial that may be used for preparing a reconstructed cornea, and also to a culture device allowing better reproducibility of the cultures of the model of reconstructed cornea.
摘要:
The invention concerns a substance for restoring normal co-expression and interaction between LOX and NRAGE proteins. In particular, the invention concerns the use of an effective amount of at least one substance modulating the expression and/or the activity of LOX having the sequence ID N°1 and/or modulating the expression and/or the activity of NRAGE having the sequence ID N°2 for making a composition for modulating the interaction between the LOX and NRAGE proteins so as to regulate the balance between the phenomena of proliferating cells, of differentiation and apoptosis, in particular in cases where the interaction between LOX and NRAGE proteins is absent or altered. The invention enables in particular skin aging, lichen planus, a graft-versus-host reaction disease, an eczema, a psoriasis, and a cancer, in particular an epithelial cancer, particularly an epithelial skin cancer, of basocellular type, or of spinocellular type to prevented or treated.
摘要:
The invention concerns active substances modulating the expression of the receptors of the products of the POMC gene (MC-1R, 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 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.
摘要:
The invention relates to a novel active ingredient that stimulates the proliferation and/or the activity of fibroblasts and also to its applications in the cosmetic or pharmaceutical, in particular dermatological, field. In particular, the active ingredient according to the invention comprises a combination of at least one Hibiscus Abelmoschus extract and a soy extract containing at least peptides.
摘要:
The present invention relates to the use of active substances that increase the activation threshold of immune cells as an active principle for the preparation of a cosmetic or pharmaceutical composition, especially a dermatological composition. The invention also relates to a method for screening such active substances.
