食品伙伴網(wǎng)報道，根據(jù)美國科技協(xié)會網(wǎng)站消息：蘑菇在眾多食品中向來被認為對保持免疫系統(tǒng)的健康起著重要作用，由美國農(nóng)業(yè)部（USDA）農(nóng)業(yè)研究局（ARS）所資助的一項動物模型和細胞培養(yǎng)的研究顯示，白色雙孢菇使免疫系統(tǒng)中的關(guān)鍵細胞活性增強。該研究結(jié)果發(fā)表在營養(yǎng)學(xué)雜志（Journal of Nutrition）上。
在美國，雙孢菇占蘑菇消費總量的90%。這項研究由美國農(nóng)業(yè)部老年營養(yǎng)中心（HNRCA）在塔夫茨大學(xué)的研究中心Simin Meydani主任、吳大勇，以及其他同事共同參與的。結(jié)果表明，白蘑菇可以促進抗病毒物質(zhì)的產(chǎn)生以及其他一些由細胞釋放可保護和修復(fù)組織的蛋白的生產(chǎn)，從而可以提高免疫功能。
這項研究的細胞培養(yǎng)階段表明，白蘑菇增強了免疫系統(tǒng)中來自骨髓的樹突狀細胞的成熟。樹突狀細胞使T細胞（血液中非常重要的一種白細胞）可以識別并最終關(guān)閉或摧毀入侵的微生物抗原。

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.
