项目摘要
<PERVの制御法の検討>1.各種糖鎖プロセシング阻害薬を用い、PERV表面のN結合型糖蛋白の高マンノース型糖鎖がヒト細胞への感染に関与することを証明した。2.次に、PERV-Bを強発現させた、独立した3系統のブタ血管内皮細胞(PEC)に、N結合型糖鎖のプロセシングに関わるα-mannosidase lb (Man lb)とN-Acetylglucosaminyltransferase l (GnT-l)およびmockを遺伝子導入した。これらの細胞由来のPERVを293細胞へ感染させ、感染細胞数の変化をnls-Lac(Z)pseudotype assayにて検討した。Manlb群の感染細胞数は、mock群に比して、それぞれ#1:33%,#2:30%,#3:29%と低下していた。Gnt-l群でも、#1:25%,#2:44%,#3:18%と低下していた。<siRNAによるPERVの制御>pBlueにpCX/GFPとpSUPER (H1 promoter)を組み込んだcassette vector : pSXGHを作成し、これにgag領域に対するsiRNAを組み込んだ(pSXGH-siRNA)。PERV-Bを強発現させたブタ血管内皮細胞(PEC)にこのvectorを遺伝子導入し、transient cell lineと、さらに数個のstable cloneを樹立した。これらの細胞由来のPERVをヒト胎児腎(HEK293)細胞へ感染させ、感染細胞数の変化をnls-Lac(Z) pseudotype assayにて検討した。1.Mockにたいして、iRNA群(transient cell line)では#1:36%,#2:39%と有意に低下していた。2.Cloneでは、mock cloneに対し#5:26%,#6:14%,#12:15%と低下していた。
& lt;PERV, Dharma, Dharma, gt;1. All kinds of carbohydrates were used to block the use of glycoproteins, N-conjugated glycoproteins on the surface of PERV, high-level glycoproteins, high-level glycoproteins, and high-level glycoprotein on the surface of Glucoprotein. two。 The secondary, PERV-B and independent 3-system were used to detect vascular endothelial cell (PEC), N-combined glucose kinase (Man lb), N-Acetylglucosaminyltransferase l (GnT-l), and mock (GnT-l), respectively. The origin of the cells was PERV 293, the number of infected cells, the number of infected cells, the number of nls-Lac (Z) pseudotype assay cells and the number of infected cells. The Manlb group is infected with the number of cells, the mock group is infected with the number of cells, the number of cells is lower than the number of cells in the mock group, the number of cells in the mock group is lower than that in the population, and the number of cells in the group is lower than that in the group. Gnt-l group fan, # 1 25% Magi 2 Rd 44% Jo 3 18% low QR. & lt;siRNA pCX/GFP PERV system & gt;pBlue pCX/GFP pSUPER (H1 promoter) system cassette vector: pSXGH system, gag domain siRNA system (pSXGH-siRNA). PERV-B strengthens the detection of vascular endothelial cell (PEC) and vector gene entry, transient cell line, and detection of several stable clone isolated cells. The cause of the infection is PERV, the fetus, the fetus, the infection, the infection, the nls-Lac (Z) pseudotype assay, the infection. 1.Mock clusters (transient cell line), iRNAs (iRNAs), iRNAs, IRNAs, iRNAs, transient cell line, iRNAs, transient cell line, iRNAs, iRNAs 2.Clone drivers, mock clone drivers, # 5, 26%, 6, 14, 14, 14, 14, 12, 15, 15, 15, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 15, 15, 15, 15, 15, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 14, 12, 15, 15, 15, 14, 14, 14, 14,
