摘要

由特异性受体介导的淋巴细胞-高内皮小静脉(HEV)细胞相互作用在正常和恶性淋巴细胞运输过程中是至关重要的。外周淋巴结、粘膜(Peyer’s patch,阑尾)和炎症关节组织(滑膜)的人淋巴细胞归巢受体HEV似乎在功能上不同,但在结构上密切相关的90 kDa糖蛋白在进化过程中高度保守。这些受体以器官特异性的方式调节淋巴细胞在全身的运输,从而决定局部免疫反应的特征,也可能决定淋巴细胞恶性肿瘤的传播模式。

Lymphocyte-endothelial cell interactions.

Lymphocyte-high endothelial venule (HEV) cell interaction that is mediated by specific receptors is fundamentally important during normal and malignant lymphocyte traffic. Putative human lymphocyte homing receptors to peripheral lymph node, mucosal (Peyer's patch, appendix) and inflamed joint tissue (synovium) HEV appear to be functionally distinct, but structurally closely related 90 kDa glycoproteins that are highly conserved during evolution. These receptors regulate lymphocyte traffic in an organ-specific manner throughout the body, thus determining the characteristics of local immune responses and possibly also the patterns of dissemination of lymphoid malignancies.
