Regulation of lipid composition of breast milk during lactation

母乳喂养的营养是所有可供人类婴儿食用的牛奶中最合适的。母乳中含有分泌型IgA抗体、溶菌酶和乳法林，可提供胃肠免疫功能。母乳中矿物质、原蛋白和脂肪的组成在运动过程中会发生变化，但它们的调节机制仍有待阐明。在本研究中，核受体超家族之一的肝脏X受体(LXR)的配体可能会影响母乳中的脂肪含量。这一结果表明，包括核受体在内的转录因子可能与哺乳过程中的母乳成分有关。

Nutrition of breast-feeding is the most appropriate of all available milks for human infants. Human milk contains secretary IgA antibodies, lysozyme, and lactofarin, which provide gastrointestinal immunity. The composition of breast milk including minerals, prorotein and fats is changed during laction, however, the regulation of them have remained to be elucidated. In the study, the ligand of liver X receptor(LXR), one of nuclear receptor superfamily may affect the lipid contents of breast milk. This result The transcriptional factors including nuclear receptors may involve components of breast milk during lactation.
