细菌黑色素与神经系统疾病的研究进展

Research progress of bacterial melanin and nervous system diseases

黑色素是广泛存在于自然界中的一类天然色素家族,苏云金芽孢杆菌突变株可获得高水平细菌黑色素,细菌黑色素能透过血脑屏障,具有抗氧化、螯合有毒金属、促进神经再生等生物学特性,可用来治疗某些与黑色素缺乏相关的神经性疾病,也能促进中枢神经系统及周围神经损伤后的结构和功能的恢复,文章就细菌黑色素在神经系统疾病的相关研究做了综述。

Melanin is a class of natural pigments family in nature. Bacterial melanin with high level of pigment synthesis-Bacillus thuringiensis was obtained. Bacterial melanin can cross the blood-brain barrier, accomplish antioxidant protection, chelate toxic metals, promote nerve regeneration. It can treat nervous system diseases with melanin deficiency, promote the structural and functional recovery of the central nervous system and peripheral nerve injury. This article summarized the research of the function of the bacterial melanin in the nervous system diseases.
