Description
技术领域
本发明属于微生物的技术领域,具体地涉及一株詹氏乳杆菌及其应用。
背景技术
皮肤是人体内最大的器官,总重量大约占个体体重的16%,一方面维持机体稳定,另一方面也是抵御外界不良因素侵扰的第一道防线。有研究表明,如果外界环境导致皮肤屏障中的相关基因异常,就会诱发皮肤疾病。
皮肤屏障是由角质层的表皮形成细胞和角质间的脂质形成的结构性的屏障。皮肤屏障防止人体过多水分释放,并防止如化学物质或微生物的有害物质进入我们的身体。组成死亡的角质细胞的表面的角质细胞外皮在细胞间脂质的稳定性中起重要作用。皮肤屏障受损将引起皮肤干燥、皮肤老化、色素沉着异位性皮炎、湿疹、银屑病、鱼鳞病、日旋光性皮炎等皮肤敏感、刺激性皮炎、激素依赖性皮炎等皮肤油腻、皮脂溢出性疾病,如痤疮、酒糟鼻、脂溢性皮炎。
角质间结构性脂质神经酰胺,在基底层向角质分化过程中含量逐渐增加,到达角质层排至细胞间隙,构成防止水分丢失的屏障。角质细胞内含水量高,随着细胞向上代谢分化,角质细胞形状会逐渐变成扁平状,且细胞核及胞器开始退化萎缩,并在角质层形成不具细胞核与胞器的死细胞。角质层本身的亲水、屏障功能,以及角质层中所含有的天然保湿因子即氨基酸类,乳酸盐及糖类等作用,使得角质层通常含有10%~30%的水分,这种环境成为了皮肤自身微生物菌落生长的摇篮。但随着年龄的增长,角质层的含水量会逐渐减少,当水分含量低于10%的时候,就会引起皮肤的各种问题。
皮肤衰老,包括由空气污染、吸烟、营养不良和紫外线(UV)等环境因素引起的外在衰老和由时间变化引起的内在衰老。其典型特征是皮肤变薄、产生细纹,这可能是由于细胞增殖减少以及随着年龄增长引起的真皮成分发生显着变化导致的。细胞外基质成分(胶原蛋白、弹性蛋白、糖胺聚糖等)随着皮肤衰老而显着减少。此外,伴随增龄,多种因素如线粒体损伤、炎症反应等产生的活性氧增加,同时,与年龄相关的细胞修复能力下降,使得氧化应激增加,老化受损细胞无法及时清除,从而导致了皮肤衰老。
詹氏乳杆菌作为一类乳酸杆菌是定殖在女性生殖道中最常见和最重要的有益菌群,在维持女性阴道健康中发挥着关键作用。其在妇科炎症方面的作用已被广泛报道,而在皮肤上的作用却鲜为人知。益生菌用在化妆品上,可平衡皮肤表皮菌群,修复皮肤屏障,抵御皮肤衰老,有效增加肌肤对营养物质的吸收,增强免疫力。
敏感肌通常是由于皮肤细胞受损而使皮肤免疫力下降,角质层变薄导致皮肤滋润度不够,最终导致肌肤的屏障功能过于薄弱,无法抵御外界刺激,从而易于产生泛红、发热、瘙痒、刺痛等不适现象的产生。因此,提供一种利用微生态技术开发的益生菌相关产品,具有重要的现实意义。
