美国费城威斯达研究所(The Wistar Institute)的科学家发现了人体免疫系统杀伤性T细胞外部的多个受体,研究人员认为,可以通过选择性标靶这些细胞使其维持在对抗疾病的状态。这项研究发现一个受体与T细胞的关闭有关,另外发现6个受体也能限制或负调节免疫应答,这些受体可能控制T Scientists at The Wistar Institute in Philadelphia, the United States, discovered multiple receptors outside of the body’s immune system killer T cells. Researchers believe they can be maintained in a disease-fighting state by selectively targeting these cells . This study found that one receptor is involved in the shut-down of T cells. In addition, six receptors were also found to be able to limit or negatively regulate the immune response, and these receptors may control T
