Herpes simplex virus vectors for gene therapy 总被引:2,自引:0,他引:2
David S. Latchman 《Molecular biotechnology》1994,2(2):179-195
Herpes simplex virus (HSV) has a number of advantages as a vector for delivering specific genes to the nervous system. These
include its large size, wide host range, and its ability to establish long-lived asymptomatic infections in neuronal cells
in which a specific region of the viral genome continues to be expressed. Unfortunately, the large size of this virus and
difficulty in manipulating it has led to its use as a vector lagging behind that of other, smaller viruses such as the retroviruses.
In addition, the virus's ability to replicate lytically in the brain, under some circumstances, causing encephalitis, has
led to fears about its potential safety for ultimate use in humans. This review will discuss a number of new approaches that
are aimed at rendering simpler the insertion of foreign genes into the virus and making it as safe as possible. Ultimately,
these advances offer real hope for the use of HSV vectors in gene therapy procedures. 相似文献

CT-1 mediated cardioprotection against ischaemic re-oxygenation injury is mediated by PI3 kinase, Akt and MEK1/2 pathways. 总被引:3,自引:0,他引:3
Cardiotrophin-1 protects cardiac myocytes from ischaemic re-oxygenation (IR) injury. CT-1 activates MEK1/2,p42/44MAPK as well as the phosphatidylinositol (PI) 3-OH kinase (PI3) protein kinase B (PKB/Akt) pathway. In this study we investigate the signalling pathways that mediate the anti-apoptotic cell survival effect of CT-1 in IR. Dominant negative gene based inhibitors of MEK1/2, PI3-kinase and Akt inhibited CT-1 mediated cardioprotection in re-oxygenation as did chemical inhibitors of the PI3-kinase pathway. Hence the PI3-kinase/Akt pathway is required in addition to MEK1/2 to mediate CT-1 cardioprotection in IR. 相似文献
