Abstract

Circulating peripheral blood lymphocyte subpopulations were analysed in patients with primary intracranial neoplasia. Patients with tumours of glial origin demonstrated a significant depletion of E-rosetting lymphocytes whereas the quantitative lymphocyte profiles of patients with non-glial brain tumours were normal. The number of immunoglobulin and Fe receptor-bearing cells was not significantly altered in any group of patients: however, the EAC-RFC subpopulation was increased in those with malignant gliomas. Two hypotheses are suggested to explain these observations: first, the presence of cross-reacting antibody between T cells and brain (glial) cells, and secondly, the proliferation of EAC-RFC in response to malignant degeneration.

摘要

对原发性颅内肿瘤患者的循环外周血淋巴细胞亚群进行了分析。胶质源性肿瘤患者的E花环形成淋巴细胞显著减少,而非胶质脑肿瘤患者的淋巴细胞定量分布正常。任何一组患者中免疫球蛋白和带有铁受体的细胞数量均无显著改变:然而,恶性胶质瘤患者的EAC-RFC亚群增加。提出了两种假说以解释这些观察结果:第一,T细胞与脑(胶质)细胞之间存在交叉反应抗体;第二,EAC-RFC因恶性变性而增殖。
