背景情况:

免疫细胞的功能是通过与其他细胞的短暂物理相互作用 ("亲吻和逃跑") 来调节的.
之前的方法如LIPSTIC仅限于特定的受体- 连接体对 (CD40L- CD40).
需要一种更广泛的方法来研究各种免疫细胞的相互作用.

研究的目的:

开发和验证用于跟踪各种细胞相互作用的普遍LIPSTIC (uLIPSTIC) 方法.
应用uLIPSTIC来研究不同生物环境中的各种免疫细胞相互作用.

主要方法:

开发uLIPSTIC,一种用于细胞间接触的多功能酶标记技术.
应用uLIPSTIC来监测T细胞培养,调节性T细胞相互作用和T毛囊辅助细胞相互作用.
整合uLIPSTIC与单细胞转录组学以编目细胞互动体.

主要成果:

uLIPSTIC成功地记录了免疫细胞之间的相互作用以及免疫和非免疫细胞之间的相互作用.
证明uLIPSTIC在识别T细胞初始化,调控性T细胞伴侣和T毛囊辅助细胞方面的有用性.
创建了免疫细胞与肠上皮细胞相互作用的目录,并分析了感染后的T细胞相互作用.

结论:

uLIPSTIC是一种广泛适用于研究细胞相互作用的技术.
这种方法提高了我们对体内免疫调节和细胞通信的理解.
uLIPSTIC可以对复杂的生物系统和免疫反应进行全面分析.

Cells of the Adaptive Immune Response

Cells of the Adaptive Immune Response

The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...
