研究了创伤（闭合伤、截肢伤、烧伤）后小鼠不同来源淋巴细胞（脾脏、胸腺、肠系膜淋巴结）白介素２受体（ＩＬ－２Ｒ）ｍＲＮＡ及ＩＬ－２Ｒ的变化，并观察了创伤后血清，巨噬细胞、Ｔｓ细胞的抑制作用。结果显示：３种类型创伤组小鼠不同来源淋巴细胞ＩＬ－２ＲｍＲＮＡ水平均降低，淋巴细胞膜ＩＬ－２Ｒ的变化与此相一致，二者呈非常显著的正相关。创伤后血清、巨噬细胞、Ｔｓ细胞在体外均可抑制正常小鼠脾细胞ＩＬ－２ＲｍＲＮＡ及ＩＬ－２Ｒ水平，去除创伤小鼠脾细胞中的巨噬细胞或Ｔｓ细胞均可致ＩＬ－２ＲｍＲＮＡ及ＩＬ－２Ｒ水平的提高。提示创伤后血清、巨噬细胞、Ｔｓ细胞可通过抑制淋巴细胞ＩＬ－２Ｒ的转录从而导致淋巴细胞膜ＩＬ－２Ｒ的减少。
To study the changes of interleukin 2 receptor (IL-2R) mRNA and IL-2R in different lymphocytes (spleen, thymus and mesenteric lymph nodes) in mice after trauma (closed injury, amputation, burn) , Macrophage, Ts cell inhibition. The results showed that the levels of IL-2R mRNA in lymphocytes of different types of trauma mice decreased, and the changes of IL-2R in lymphocyte membrane were consistent with the three types of wounds. The two showed a very significant positive correlation. Traumatic serum, macrophages, Ts cells in vitro can inhibit the normal mouse spleen IL-2R mRNA and IL-2R levels, removal of trauma mouse spleen cells in macrophages or Ts cells can cause IL-2R mRNA and IL-2R levels increased. It is suggested that posttraumatic serum, macrophages and Ts cells can induce the decrease of IL-2R in lymphocytes by inhibiting the transcription of IL-2R in lymphocytes.
