如今，一项新的研究确定了与T细胞沟通从而促使它们耐受、攻击或简单地忽略的特定肠道细胞类型，并解释了这些相反的反应是如何触发的。这一发现让科学家们对肠道免疫系统如何保持肠道平衡有了新的认识，并可能最终揭示 食物过敏 ...

A stable interaction between antigen-presenting cells (APC) and T cells is dependent not only on the absolute affinity between the T-cell receptor (TCR) and its ligand but also on the relative ...

Antigen-presenting cells work to present peptides derived from exogenous and endogenous antigens to circulating T cells, sparking off an immune response. Dendritic cells are unique amongst antigen ...

Glucocorticoid-induced tumor necrosis factor receptor (GITR) and its ligand, GITRL, are involved in immune response ...

But a study published yesterday (September 15) in Nature Cell Biology suggests that an interaction between T cells and antigen presenting cells (APCs) early in the immune response to viruses may ...

The intestinal immune system is complicated machinery. Tolerance to food begins with antigen presenting cells, or APCs, instructing T cells to stand down. This signal gives rise to pTregs ...
