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 ...

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 ...

Study reveals how immune cells in the gut distinguish between food and harmful pathogens, shedding light on the origins of both food allergies and intestinal diseases.

Cell-cell interactions help drive tolerogenic or inflammatory responses to the maelstrom of antigens passing through the gut.

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 ...

Food allergies can be life-threatening due to the rapid and exaggerated immune response. While mucosal mast cells (MMCs) are excessively proliferated during food allergies, the precise mechanisms that ...

Food allergy, or the aggressive immune system reaction following the consumption of a certain food or food ingredient, typically involves immunoglobulin E (IgE) antibodies and can be potentially ...

A phase 1 study of a personalized cancer vaccine demonstrated antitumor immunity in all treated patients with resected renal ...
