人呼吸道合胞病毒(RSV)编码两种糖蛋白(F和G),其已被证明是宿主抗体应答的主要靶标。我们已经表达了一种新的嵌合糖蛋白(FG)在昆虫细胞中使用杆状病毒载体。嵌合糖蛋白含有与RSV G糖蛋白的胞外区连接的RSV F糖蛋白的信号区和胞外区。从氨基末端开始,嵌合糖蛋白由来自RSV F的氨基酸1至489,随后是来自RSV G的氨基酸97至279组成。嵌合FG糖蛋白不含锚区,并有效地分泌到重组杆状病毒感染的昆虫细胞的培养基中。FG糖蛋白的大小范围从69 K到91 K,并且相对于等电点是异质性的。F糖蛋白上存在的切割位点在嵌合FG上被识别,并且该糖蛋白似乎与天然RSV F和G糖蛋白抗原性相似。
Human respiratory syncytial virus (RSV) codes for two glycoproteins (F and G) which have been shown to the major targets for the host antibody response. We have expressed a novel chimeric glycoprotein (FG) in insect cells using a baculovirus vector. The chimeric glycoprotein contains the signal and extracellular regions of the RSV F glycoprotein linked to the extracellular region of the RSV G glycoprotein. Beginning at the amino terminus, the chimeric glycoprotein consists of amino acids 1 to 489 from RSV F followed by amino acids 97 to 279 from RSV G. The chimeric FG glycoprotein did not contain an anchor region and was efficiently secreted into the medium of recombinant baculovirus-infected insect cells. The FG glycoprotein ranged in size from 69K to 91K and was heterogeneous with respect to isoelectric point. The cleavage site present on the F glycoprotein was recognized on the chimeric FG, and the glycoprotein appeared to be antigenically similar to the native RSV F and G glycoproteins.
