In the present study, we investigated the anti-inflammatory and anti-melanogenic effects of subsp. DB-21-derived exosomes (DB-21 exosomes), isolated from flower in lipopolysaccharide (LPS)-induced RAW 264.7 macrophage cells and melanocyte-stimulating hormone (α-MSH)-induced B16F10 melanoma cells. We confirmed that DB-21 exosomes were not toxic to LPS-induced RAW 264.7 macrophage cells and α-MSH-induced B16F10 melanoma cells. Moreover, we confirmed that DB-21 exosomes inhibit the pro-inflammatory cytokines IL-6, IL-1β, TNF-α, PGE, and the expression of inflammatory factors iNOS and COX-2. We also found that DB-21 exosomes have a concentration-dependent ability to inhibit melanin, TRP-1, TRP-2, tyrosinase, and MITF, which are factors involved in melanogenesis. Additionally, it inhibits the phosphorylation of Akt and GSK-3β, and MAP kinase pathway proteins such as ERK, JNK, and p38. We confirmed that DB-21 exosomes inhibit melanin synthesis in B16F10 cells through various pathways, and based on previous results, they may be used as a functional cosmetic material with anti-inflammatory and anti-melanogenic activities.
在本研究中,我们研究了从[花名]亚种DB - 21中分离出的外泌体(DB - 21外泌体)在脂多糖(LPS)诱导的RAW 264.7巨噬细胞和促黑素细胞激素(α - MSH)诱导的B16F10黑色素瘤细胞中的抗炎和抗黑素生成作用。我们证实DB - 21外泌体对LPS诱导的RAW 264.7巨噬细胞和α - MSH诱导的B16F10黑色素瘤细胞无毒。此外,我们证实DB - 21外泌体可抑制促炎细胞因子IL - 6、IL - 1β、TNF - α、PGE以及炎症因子iNOS和COX - 2的表达。我们还发现DB - 21外泌体具有浓度依赖性抑制黑色素、TRP - 1、TRP - 2、酪氨酸酶和MITF的能力,这些都是参与黑素生成的因子。此外,它还抑制Akt和GSK - 3β以及MAP激酶途径蛋白如ERK、JNK和p38的磷酸化。我们证实DB - 21外泌体通过多种途径抑制B16F10细胞中的黑色素合成,基于先前的结果,它们可用作具有抗炎和抗黑素生成活性的功能性化妆品原料。
