Targeted RNA Cleavage and Antiviral Activity
Hairpin ribozymes have been modified in such a way that they can be used to target cleavage of other RNA molecules. This is possible because much of the substrate specificity of the hairpin ribozyme results from simple Watson-Crick base pairing within helices 1 and 2.
One area of particular interest has been the development of hairpin ribozymes for potential therapeutic use, for example by preventing the replication of pathogenic viruses. Antiviral hairpin ribozymes have been generated and expressed within mammalian cells, and cells expressing different engineered ribozymes have been shown to be resistant to infection by HIV-1, hepatitis B, and Sindbis virus.

Famous quotes containing the words cleavage and/or activity:
“Jesus abolished the very concept of “guilt”Mhe denied any cleavage between God and man. He lived this unity of God and man as his “glad tidings” ... and not as a prerogative!”
—Friedrich Nietzsche (1844–1900)
“For universal love is as special an aspect as carnal love or any of the other kinds: all forms of mental and spiritual activity must be practiced and encouraged equally if the whole affair is to prosper. There is no cutting corners where the life of the soul is concerned....”
—John Ashbery (b. 1927)
