A groundbreaking study published in the journal Cell has unveiled a fascinating link between the amino acid arginine and our immune health.
一項發表在《細胞》期刊上的突破性研究揭示了氨基酸精氨酸與我們免疫健康之間令人著迷的聯繫。
Researchers at Rockefeller University discovered that arginine is essential for producing MHC-1 proteins, which act as critical "warning signals" that alert our immune system to threats like cancer or viruses.
洛克斐勒大學的研究人員發現，精氨酸對於產生MHC-1蛋白至關重要，這些蛋白充當關鍵的「預警信號」，提醒我們的免疫系統注意癌症或病毒等威脅。
When arginine levels are low, these signals fail to activate, leaving the body vulnerable.
當精氨酸水平偏低時，這些信號無法啟動，使身體處於脆弱狀態。
Experiments in mice showed that an arginine-rich diet could help shrink colon tumors and improve survival against influenza and COVID-19.
在小鼠身上進行的實驗顯示，富含精氨酸的飲食有助於縮小結腸腫瘤，並提高對流感和COVID-19的存活率。
Arginine, a semi-essential amino acid found in turkey, lentils, and pumpkin seeds, has long been associated with cardiovascular health, but this discovery highlights its vital role in immune surveillance.
精氨酸是一種存在於火雞肉、扁豆和南瓜籽中的半必需氨基酸，長期以來與心血管健康有關，但這一發現突顯了它在免疫監測中的重要作用。
They warn that consuming excessive amounts of arginine is not a simple "cure-all" for everyone, as the interplay between nutrition and disease is complex.
他們警告說，攝取過量的精氨酸並非人人適用的萬靈丹，因為營養與疾病之間的相互作用相當複雜。
While these findings are exciting, the research team emphasizes that human clinical trials are necessary to confirm if supplemental arginine could be an effective, affordable therapy for patients.
儘管這些發現令人振奮，研究團隊仍強調，需要透過人體臨床試驗來確認補充精氨酸是否能成為患者有效且經濟實惠的療法。
