The CRISPR/Cas9 technology is currently revolutionizing the field of molecular biology research and is opening up many new avenues for potential therapies for many diseases in the future. The CRISPR technique is a new weapon against dormant herpes viruses in the body, which cause cold sores and can be implicated in blindness and cancer. For some, just the word alone can result in a rollercoaster of emotions. Read on to know more about this. Cold sores are HSV-1(herpes simplex 1) and genital herpes are HSV-2. DNA double-stranded breaks can effectively induce homologous recombination in mammalian cells [] and this mechanism can be harnessed. Step 1) Adaptation: CRISPR system allows integration of short pieces of the viral DNA into the CRISPR locus Step 2) crRNA ("CRISPR RNA") biogenesis: CRISPR sequences are transcribed and the crRNA interact with Cas9 to form "Interference Complexes" Step 3) Interference: base pairs with matching sequences in viral DNA to interfere with it. Taylor The Complete DNA Sequence of Varicella-Zoster Virus Andrew J. What is the current status with this? I read about a hopeful research group. To test this, the researchers devised specific guide (g)RNAs—sequences that are. EDIT: The key here would be find or design a vector for the CRISPR complex that would specifically target only infected neurons. But curing herpes will do more than just do away with stigma.
