Abstract

A skin protection method, for preventing cellular aging, involves use of: (i) heat shock proteins (I) isolated from algae; or (ii) molecules (II) isolated from algae which induce constitutive and/or inductive heat shock proteins in the skin cells. Independent claims are included for: (a) a pharmaceutical or cosmetic composition for preventing cellular aging of the skin, containing (I) or (II) as active agent; and (b) the preparation of such compositions, by using an algal extract containing (I) (constitutive and/or inductive) or (II).

Description

La présente invention concerne un procédé de protection de la peau pour laThe present invention relates to a method of protecting the skin for the

prévenir de son vieillissement cellulaire.  prevent cell aging.

Le but de la présente invention est de proposer un tel procédé qui soit nouveau.  The object of the present invention is to propose such a process which is new.

Selon la présente invention, ce procédé consiste à utiliser des protéines de choc thermique isolées d'algues. La présente invention concerne également une composition pharmaceutique ou cosmétique destinée à prévenir le vieillissement cellulaire de la peau qui est caractérisée en ce qu'elle comporte à titre de principe actif des protéines de choc  According to the present invention, this method consists in using heat shock proteins isolated from algae. The present invention also relates to a pharmaceutical or cosmetic composition intended to prevent cellular aging of the skin which is characterized in that it comprises, as active principle, shock proteins

thermique isolées d'algues.thermal isolated from algae.

Les protéines de choc thermique sont des protéines chaperonnes produites par  Heat shock proteins are chaperone proteins produced by

les cellules pour lutter contre des oxydations liées à des dérivés réactifs de l'oxygène.  cells to fight against oxidations linked to reactive oxygen derivatives.

Elles sont connues sous le nom de protéines de choc thermique (Heat Shock Proteins)  They are known as Heat Shock Proteins

ou sous l'abréviation hsp.or under the abbreviation hsp.

Ces protéines sont exprimées dans les cellules cutanées humaines telles que les kératinocytes et les fibroblastes. La production de ces protéines hsp est stimulée par des stress telle qu'une augmentation de température (d'o leur nom), une exposition aux UVB, etc. On sait par ailleurs que les algues expriment des marqueurs biologiques de réponse à un stress. Ces marqueurs sont des protéines qui présentent une structure très proche de celle des protéines hsp de mammifères. Des homologies de séquence ont  These proteins are expressed in human skin cells such as keratinocytes and fibroblasts. The production of these hsp proteins is stimulated by stresses such as an increase in temperature (hence their name), exposure to UVB, etc. We also know that algae express biological markers in response to stress. These markers are proteins which have a structure very close to that of mammalian hsp proteins. Sequence homologies have

montré la présence des gènes codant des protéines hsp dans des algues.  demonstrated the presence of genes encoding hsp proteins in algae.

Il a par exemple été montré que des algues du genre Chlorella exposée à 40 C pendant 30 minutes augmentent la quantité de protéines hsp de 43, 60, 73 et 95 Kda et induisent l'expression d'une protéine hsp 27 Kda. Ces protéines protègent ces algues Chlorella contre une incubation ultérieure à 45 C. On a pu montrer qu'une composition pharmaceutique ou cosmétique dont le principe actif est constitué de protéines de choc thermique isolées d'algues a une  For example, it has been shown that algae of the genus Chlorella exposed to 40 ° C. for 30 minutes increase the quantity of hsp proteins by 43, 60, 73 and 95 Kda and induce the expression of a hsp 27 Kda protein. These proteins protect these Chlorella algae against a subsequent incubation at 45 C. It has been shown that a pharmaceutical or cosmetic composition whose active principle consists of thermal shock proteins isolated from algae has a

influence sur le vieillissement des cellules cutanées.  influence on the aging of skin cells.

Cette influence est corroborée par des études sur le vieillissement qui ont mis en évidence une relation entre l'âge des cellules cutanées humaines et le taux basal de protéines de choc thermique ou entre l'âge des cellules et l'aptitude à exprimer des  This influence is corroborated by studies on aging which have shown a relationship between the age of human skin cells and the basal level of heat shock proteins or between the age of cells and the ability to express

protéines de choc thermique après un choc thermique.  heat shock proteins after heat shock.
