The studies described were designed to examine the question of cross-reactivity between basic protein of myelin and a basic protein common to many human tumours. The lymphocytes from guinea-pigs injected with acid extracts of human cancer tissue showed significant (P less than 0-01) tranformation on exposure to basic protein of human myelin. Conversely lymphocytes from guinea-pigs injected with basic protein of human myelin showed significant (P less than 0-01) transformation on exposure to the acid extracts of human cancer tissue. Lymphocytes from control non-injected guinea-pigs did not transform on exposure to either antigen. These findings demonstrate immunological cross-reactivity in guinea-pigs between basic proteins of human myelin and of human cancer tissue using an assay system other than the macrophage electrophoretic migration hitherto used to show this effect in man.
所描述的这些研究旨在探讨髓磷脂碱性蛋白与许多人类肿瘤所共有的一种碱性蛋白之间的交叉反应问题。用人类癌组织酸性提取物注射的豚鼠的淋巴细胞,在接触人类髓磷脂碱性蛋白时显示出显著(P小于0.01)的转化。相反,用人类髓磷脂碱性蛋白注射的豚鼠的淋巴细胞,在接触人类癌组织酸性提取物时显示出显著(P小于0.01)的转化。未注射的对照豚鼠的淋巴细胞在接触任何一种抗原时都不发生转化。这些发现表明,使用一种不同于迄今用于在人类中显示这种效应的巨噬细胞电泳迁移分析系统,豚鼠体内人类髓磷脂碱性蛋白与人类癌组织碱性蛋白之间存在免疫交叉反应。
