Abstract

B lymphocytes synthesize and then express in their surface membranes immunoglobulin (Ig) molecules which serve as antigen receptors. Although controversy surrounds the precise nature of antigen receptors in T lymphocytes, these receptor molecules react with certain anti-Ig reagents and are considered to be Ig-related. Antiglobulin rosette tests and in particular the mixed antiglobulin rosetting reaction (MARR) and the direct antiglobulin rosetting reaction (DARR) have special merit in demonstration of lymphocyte Ig and Ig-related surface determinants; these lest systems are reviewed and compared with more conventional direct binding methodology which uses free anti-Ig molecules to sensitize lymphocytess.

摘要

B淋巴细胞合成免疫球蛋白(Ig)分子,然后将其表达于细胞膜表面,这些分子作为抗原受体。尽管关于T淋巴细胞抗原受体的确切性质存在争议,但这些受体分子能与某些抗Ig试剂发生反应,被认为与Ig相关。抗球蛋白玫瑰花结试验,尤其是混合抗球蛋白玫瑰花结反应(MARR)和直接抗球蛋白玫瑰花结反应(DARR),在显示淋巴细胞Ig及Ig相关表面决定簇方面具有特殊价值;本文对这些试验系统进行了综述,并与使用游离抗Ig分子致敏淋巴细胞的更传统直接结合方法进行了比较。
