食品伙伴网报道，根据美国科技协会网站消息：蘑菇在众多食品中向来被认为对保持免疫系统的健康起着重要作用，由美国农业部（USDA）农业研究局（ARS）所资助的一项动物模型和细胞培养的研究显示，白色双孢菇使免疫系统中的关键细胞活性增强。该研究结果发表在营养学杂志（Journal of Nutrition）上。
在美国，双孢菇占蘑菇消费总量的90%。这项研究由美国农业部老年营养中心（HNRCA）在塔夫茨大学的研究中心Simin Meydani主任、吴大勇，以及其他同事共同参与的。结果表明，白蘑菇可以促进抗病毒物质的产生以及其他一些由细胞释放可保护和修复组织的蛋白的生产，从而可以提高免疫功能。
这项研究的细胞培养阶段表明，白蘑菇增强了免疫系统中来自骨髓的树突状细胞的成熟。树突状细胞使T细胞（血液中非常重要的一种白细胞）可以识别并最终关闭或摧毁入侵的微生物抗原。

Mushrooms are among the many foods thought to play an important role in keeping the immune system healthy. Now, USDA Agricultural Research Service (ARS)-funded scientists have conducted an animal-model and cell-culture study showing that white button mushrooms enhanced the activity of critical cells in the body’s immune system. In the United States, white button mushrooms represent 90% of the total mushrooms consumed.
The study was conducted at the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University by Center Director Simin Meydani, colleague Dayong Wu, and others. The results suggest that white button mushrooms may promote immune function by increasing production of antiviral and other proteins that are released by cells while seeking to protect and repair tissue.
The study’s cell-culture phase showed that white button mushrooms enhanced the maturity of immune system cells called “dendritic cells,” from bone marrow. Dendritic cells can make T cells-important white blood cells that can recognize and eventually deactivate or destroy antigens on invading microbes.
When immune system cells are exposed to disease-causing pathogens, such as bacteria, the body begins to increase the number and function of immune system cells, according to Meydani. People need an adequate supply of nutrients to produce an adequate defense against the pathogen. The key is to prevent deficiencies that can compromise the immune system.
