我们从小鼠肥大细胞和巨噬细胞系中分离出编码小鼠白细胞介素 10 受体 (mIL-10R) 的 cDNA。这两个 cDNA 基本相同,并且在 COS7 细胞中表达几乎等于 110 kDa 的多肽,该多肽特异性结合 mIL-10。表达转染的重组 mIL-10R 的小鼠原 B 细胞系 (Ba/F3) 以高亲和力(几乎等于 70 pM)结合 IL-10,并响应 mIL-10 进行增殖。 mIL-10R 在结构上与干扰素受体 (IFNR) 相关。由于 IL-10 通过 IFN-γ 抑制巨噬细胞活化,因此这种关系的可能暗示是 IL-10R 和 IFN-γR 或其信号传导途径的相互作用。
We isolated cDNAs encoding a mouse interleukin 10 receptor (mIL-10R) from mouse mast cell and macrophage cell lines. The two cDNAs are substantially identical and express an almost-equal-to 110-kDa polypeptide in COS7 cells, which binds mIL-10 specifically. A mouse pro-B-cell line (Ba/F3) expressing transfected recombinant mIL-10R binds IL-10 with high affinity (almost-equal-to 70 pM) and proliferates in response to mIL-10. mIL-10R is structurally related to interferon receptors (IFNRs). Since IL-10 inhibits macrophage activation by IFN-gamma, a possible implication of this relationship is interaction of IL-10R and IFN-gammaR or their signaling pathways.
