贫血是铁缺乏的一个表现,最广为人知,但非最要紧。生命最初的1000天,铁元素对胚胎乃至新生婴儿神经系统的发育一直有重要影响。为何要重视铁缺乏?脑白质中的少突胶质细胞能包绕轴突构成髓鞘化的神经纤维,少突胶质细胞是脑内含铁最丰富的细胞,上面有铁蛋白结合位点,它需要铁元素作为辅因子参与细胞内DNA合成、呼吸链(提供能量包)、神经递质代谢及脂类合成等。铁缺乏时,
Anemia is a manifestation of iron deficiency, the most widely known, but not the most important. In the first 1,000 days of life, iron has always had a major impact on the development of the nervous system of embryos and even newborn babies. Why should pay attention to the lack of iron? The oligodendrocytes in the white matter of the brain can wrap around the axons to form myelinated nerve fibers, oligodendrocytes are the most abundant iron-containing cells in the brain with ferritin binding sites , Which requires iron as a cofactor to participate in intracellular DNA synthesis, the respiratory chain (to provide energy packs), neurotransmitter metabolism and lipid synthesis. Iron deficiency,
