使用单克隆抗体识别所有的γ/δ和α/β T细胞受体的细胞荧光分析,我们比较了肠上皮内淋巴细胞(i-IEL)在正常胸腺和无胸腺无菌(GF)和常规(SPF)小鼠的组成。结果表明,微生物定植对单阳性(CD 4+或CD 8+)α/β i-IEL的数量有显著影响,但对γ/δ i-IEL的样本池大小或特征几乎没有影响。在年轻的无胸腺小鼠中,几乎没有检测到α/β i-IEL,而相当数量的γ/δ i-IEL仍然存在,尽管在GF动物中减少。
Using monoclonal antibodies identifying all gamma/delta and alpha/beta T cell receptors in cytofluorometric analysis, we have compared the composition of intestinal intraepithelial lymphocytes (i-IEL) in euthymic and athymic germ-free (GF) and conventional (SPF) mice. The results show a marked influence of microbial colonization in the numbers of single-positive (CD4+ or CD8+) alpha/beta i-IEL, but little effect in the pool size or characteristics of gamma/delta i-IEL. In young athymic mice, virtually no alpha/beta i-IEL are detected, while considerable numbers of gamma/delta i-IEL remain, though reduced in GF animals.
