Acné L'acné (nom féminin) est une dermatose (maladie de la peau) inflammatoire des follicules pilosébacés (glandes sécrétant le sébum, à la racine des poils) avec formation de comédons.
Cette maladie de la peau est représentée dans sa forme la plus fréquente par l'acné polymorphe juvénile qui touche les adolescents, mais qui ne résume pas toutes les acnés. Il existe aussi des acnés exogènes d'origine professionnelle, médicamenteuse, cosmétique...

| Résumé : |
Although it has been known for many years that peroxidation of lipids in skin is increased by sunlight and atmospheric pollution, and that the products contribute to the ageing of skin, sunburn, and skin cancers, relatively little attention has been given to the process. This has largely been owing to the absence of a technology to protect tissues from the products of lipid peroxidation.
However, this may be about to change thanks to a UK start-up created by two former Oxford medical scientists, one of whom was the co-discoverer of the protective effect of high-density lipoproteins (HDL, commonly known as 'good' cholesterol) against heart disease.
The founders knew from their academic cardiovascular research that one of th eprotein components of HDL particles is able to protect vascular cells from the toxic effects of lipid peroxides by sequestering them, and that peptides had been synthesized with even greater affinity for the molecules, even though they had no sequence homology to the HDL protein.
The idea of transferring the technology to skincare had been prompted when they discovered, when studying HDLs in tissue fluid collected from the skin of healthy volunteers, that the concentration of lipid peroxides in the fluid was many times greater than could be explained by the level in blood. |
