(result)
As shown in FIG. 1, TNF-α was expressed at 38 pg / ml due to inflammation caused by PMA stimulation. However, by adding 0.001% of polypeptide 1, even when PMA was added, the expression level of TNF-α was as small as 8 pg / ml, and inflammation could be suppressed.
As shown in FIG. 2, the expression level of MMP-9 was 171 pg / ml before PMA addition, but MMP-9 increased to 1650 pg / ml due to inflammation after PMA addition. On the other hand, by adding 0.001% of polypeptide 1, even when PMA was added, the expression level of MMP-9 was 277 pg / ml, the same level as before PMA addition, and inflammation could be suppressed.
As shown in FIG. 3, the expression level of NGAL was 6815 pg / ml before PMA addition, but NGAL increased to 12236 pg / ml due to inflammation after PMA addition. On the other hand, by adding 0.001% of polypeptide 1, even when PMA was added, the expression level of NGAL was 8340 pg / ml, a value close to that before PMA addition, and inflammation could be suppressed.
As shown in FIG. 4, the expression level of IL-8 was 94 pg / ml before the addition of PMA, but IL-8 increased to 5180 pg / ml due to inflammation after the addition of PMA. On the other hand, by adding 0.001% of polypeptide 1, the expression level of IL-8 was reduced to 2736 pg / ml even when PMA was added, and inflammation could be suppressed.

２４時間培養後、培養上清を回収し、培養上清中のＭＭＰ−９、ＮＧＡＬ量をＥＬＩＳＡ ｋｉｔ（Ｒ＆Ｄ ｓｙｓｔｅｍｓ社）を用いて測定した。結果を図５、６に示す。
Propionibacterium acnes (NBRC 107605) was used as an acne bacterium. After anaerobic culture at 35 ° C. for 5 days using a GAM agar medium, it was dispersed in phosphate buffered saline (PBS), and the number of bacteria was measured. After the number of bacteria was measured, the mixture was fixed with 4% paraformaldehyde / PBS (−) for 30 minutes while shaking, washed twice with PBS (−), and then dispersed in PBS (−) to obtain a killed acne bacteria solution.
HEKn adjusted to 1 × 10 5 cells / well / 2 ml was cultured in Epi-Life · KG2 medium at 37 ° C. in a 5% CO 2 incubator until it became subconfluent.
After culturing, the Epinelifer KG2 medium is adjusted to a concentration of 1 × 10 8 cfu / ml of the Acne killed bacteria solution, and polypeptide 1 is 0.0001%, 0.0005%, 0.001%, respectively. The medium was replaced with the added culture medium, and the cells were cultured in a 37 ° C., 5% CO 2 incubator. In addition, the thing which did not add polypeptide 1 was set to control.
After culturing for 24 hours, the culture supernatant was collected, and the amounts of MMP-9 and NGAL in the culture supernatant were measured using ELISA kit (R & D systems). The results are shown in FIGS.
（結果）
図５に示したように、Ｐ．ａｃｎｅｓの死菌添加前はＭＭＰ−９の発現量が４２８ｐｇ／ｍｌであったが、Ｐ．ａｃｎｅｓの死菌添加後の炎症により、ＭＭＰ−９が１４３２ｐｇ／ｍｌと増大した。一方、ポリペプチド１を０．０００１％、０．０００５％、０．００１％添加することにより、Ｐ．ａｃｎｅｓの死菌を添加してもＭＭＰ−９の発現量はそれぞれ７０１ｐｇ／ｍｌ、４９２ｐｇ／ｍｌ、３８５ｐｇ／ｍｌと小さくなり、添加量に依存して、炎症を抑制した。特に、ポリペプチド１を０．００１％添加することにより、Ｐ．ａｃｎｅｓの死菌の添加前後でＭＭＰ−９の発現量が変わらず、炎症を抑制できた。
図６に示したように、Ｐ．ａｃｎｅｓの死菌添加前はＮＧＡＬの発現量が５１００ｐｇ／ｍｌであったが、Ｐ．ａｃｎｅｓの死菌添加後の炎症により、ＮＧＡＬが７４３９ｐｇ／ｍｌと増大した。一方、ポリペプチド１を０．０００１％、０．０００５％、０．００１％添加することにより、Ｐ．ａｃｎｅｓの死菌を添加してもＮＧＡＬの発現量はそれぞれ５８１５ｐｇ／ｍｌ、６２９０ｐｇ／ｍｌ、５２１８ｐｇ／ｍｌと小さくなり、炎症を抑制できた。特に、ポリペプチド１を０．００１％添加することにより、Ｐ．ａｃｎｅｓの死菌の添加前後でＮＧＡＬの発現量が変わらず、炎症を抑制できた。
すなわち、ポリペプチド１は、Ｐ．ａｃｎｅｓ死菌による炎症に対する抗炎症効果があり、にきび改善作用を有することが確認できた。
