In this study, the frequency of uropod formation and the type of lymphocyte bearing the uropod was investigated in various guinea pig lymphocyte populations. Without prior in vitro stimulation, almost 40% of peritoneal exudate lymphocytes (PELS) form uropods, while thymocytes and lymph node cells form far fewer. Subsequent stimulation in vitro with purified protein derivative demonstrated that there is an association between antigen reactivity and frequency of uropod formation in these populations. The ultrastructure of these uropods is identical to that described for human lymphocytes stimulated with phytohemagglutinin. In the populations studied, all the lymphocytes forming uropods lack easily detectable surface membrane immunoglobulin and are therefore most likely thymus-derived or T lymphocytes.
在本研究中,我们调查了不同豚鼠淋巴细胞群体中尾足形成的频率以及带有尾足的淋巴细胞类型。未经事先体外刺激时,近40%的腹腔渗出淋巴细胞(PELS)会形成尾足,而胸腺细胞和淋巴结细胞形成的尾足则少得多。随后用纯化蛋白衍生物进行体外刺激表明,这些群体中抗原反应性与尾足形成频率之间存在关联。这些尾足的超微结构与用植物血凝素刺激的人类淋巴细胞所描述的相同。在所研究的群体中,所有形成尾足的淋巴细胞均缺乏易于检测到的表面膜免疫球蛋白,因此很可能是胸腺来源的或T淋巴细胞。
