The present invention relates to a dermatopontin production promoter.

加齢や紫外線等の外来ストレスにより生じるシワ、シミの発生、皮膚弾性の低下といった皮膚の老化症状には、皮膚真皮の線維芽細胞の機能低下やマトリックス線維の減少または分解、変性が重要な要因となっている。従って、皮膚の老化防止、改善作用を有する皮膚外用剤を得るため、線維芽細胞の賦活あるいは増殖促進作用を有する成分や、マトリックス線維の産生を促進する成分に関して検討が行われている。 For skin aging symptoms such as wrinkles and spots caused by external stress such as aging and ultraviolet rays, skin dermal symptom such as decreased skin fibroblast function, matrix fiber decrease or degradation, and degeneration are important factors It has become. Therefore, in order to obtain a skin external preparation having an effect of preventing and improving skin aging, a component having an activity of promoting or promoting the proliferation of fibroblasts and a component promoting the production of matrix fibers have been studied.

例えば、皮膚の老化防止、改善作用を有する皮膚外用剤を得るために、真皮線維芽細胞の賦活あるいは増殖促進作用を有する成分としてポンカンのエッセンス(特許文献1参照)、ツリガネニンジン属植物の抽出物(特許文献2参照)、クロレラ抽出物(特許文献3参照)、ビワ抽出物(特許文献4参照)、オオボウシバナ由来のフラボノイド(特許文献5参照)等が開示されている。

また、皮膚内部の細胞外マトリックスではコラーゲンが多く含まれていることはよく知られている。この他にも非コラーゲン成分が多種存在し、種々の生理活性を有する。非コラーゲン成分としてはエラスチンやプロテオグリカンが量的に多いということは以前より知られてきたが、低分子量の分子については着目されていなかった。しかし1989年にプロテオグリカンの1つであるデコリンの精製時に、分子量22kDaの蛋白質が同時に精製され、後にデルマトポンチンと命名された(非特許文献1)。その後、細胞外マトリックス成分であるデルマトポンチンの機能解析が行われている(非特許文献2)。

It is well known that the extracellular matrix inside the skin contains a large amount of collagen. In addition to these, there are various non-collagen components and various physiological activities. It has been known for a long time that elastin and proteoglycan are quantitatively large as non-collagen components, but attention has not been paid to low molecular weight molecules. However, in 1989, when decorin, one of the proteoglycans, was purified, a protein with a molecular weight of 22 kDa was simultaneously purified and later named dermatopontin (Non-patent Document 1). Thereafter, functional analysis of dermatopontin, which is an extracellular matrix component, has been performed (Non-patent Document 2).
