Another subject of the invention relates to a cosmetic care process comprising the topical application of the extract according to the invention or of the cosmetic composition comprising same, for decreasing the pigmentation of the skin and/or of the skin appendages, and/or decreasing the pigment spots on the skin. Yet another subject of the invention relates to the L. domesticum leaf extract for the pharmaceutical, preferentially dermatological, use thereof in the treatment of pathological conditions involving a pigment dysregulation.

Abstract: The present invention relates to a novel sebum secretion inhibitor and use thereof for the production of cosmetic and pharmaceutical, notably dermatological, compositions, intended for preventing and/or reducing the secretion of sebum and notably of squalene.

Abstract: The invention relates to active ingredients capable of stimulating direct or indirect expression of type 2 human beta-defensins and/or type 3 human beta-defensins. The invention thus provides an active ingredient capable of stimulating direct or indirect expression of type 2 human beta-defensins and/or type 3 human beta-defensins, characterized in that the active ingredient does not cause any inflammatory, irritation or intolerance reactions. The invention also provides a screening method for the selection of such active ingredients. The invention is applicable to the preparation of cosmetic or pharmaceutical compositions containing such active ingredients.

Abstract: The disclosed substance restores normal co-expression and interaction between the LOX and NRAGE proteins. Particularly, an effective amount of the substance that modulates the expression and/or activity of LOX of SEQ ID NO: 1 and/or that modulates the expression and/or activity of NRAGE of SEQ ID NO: 2, may be used for the manufacture of a composition for modulating the interaction between the LOX and NRAGE proteins to regulate the balance between the cellular phenomena of proliferation, differentiation and apoptosis, particularly in cases where the balance between these phenomena is disturbed, and especially in cases where the interaction between LOX and NRAGE is absent or altered. The invention makes it possible especially to treat and/or prevent skin ageing, lichen planus, graft-versus-host reaction (GVH), eczema, psoriasis and a cancer, particularly an epithelial cancer and more particularly a cutaneous epithelial cancer of basocellular or spinocellular type.

Abstract: The invention relates to the use of a substance for restoring normal co-expression and interaction between the LOX and NRAGE proteins. The invention relates in particular to the use of an effective amount of at least one substance that modulates the expression and/or activity of the LOX of SEQ ID NO: 1 and/or that modulates the expression and/or activity of the NRAGE of SEQ ID NO: 2 for modulating the interaction between the LOX and NRAGE proteins to regulate the balance between the cellular proliferation, differentiation and apoptosis, particularly in cases where the balance between these phenomena is disturbed, and especially in cases where the interaction between LOX and NRAGE is absent or altered.

Abstract: The invention relates to the stimulation of the synthesis and of the activity of an isoform of lysyl oxidase, and more particularly of the LOXL (lysyl oxidase-like) isoform. The invention relates notably to a method of identifying an active principle which stimulates the formation of elastic fibers. The aim of the invention is mainly to provide such a method of identification so as to provide compositions which enable stimulating the formation of elastic fibers.

Abstract: The invention concerns active substances modulating the expression of the receptors of the products of the POMC gene (MC-IR, MC-2R, and the ? 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 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.
