Can viruses be used to diminish the effects of genes?

In summary, the conversation discusses the possibility of using viruses to diminish the effects of genes. While viruses have been engineered for this purpose, they often do not replicate and are not suitable for all cell types. However, it is possible to create a virus that replicates and affects genes, but it would need to be carefully designed to avoid causing harm.

Can viruses be used to diminish the effects of genes? My friend said they couldn't be because we didn't understand enough about the mechanisms behind viruses and she gave some other reasons...but she was in a hurry and she might not have understood what i was asking...so I was wondering if a virus could be to used to stop/lower the effect of a gene or two, (in things that arent embroys) and why or why not

thanks

Scientist already use viruses but these viruses have been engineered/modified to suit the purpose. However, these viruses, more often than not, do not replicate.

Do they not replicate for safety purposes?
A virus that replicates could be used/created though right? (To diminish the effects of a gene)

I'm fairly sure that the guts of the virus are completely replaced with siRNA, leaving the virus only able to efficiently inject the cargo into a cell. Otherwise the cure would be worse than the disease?

a virus couldn't be used to affect genes in every cell type because it would probably be too tissue-specific right?
 

FAQ: Can viruses be used to diminish the effects of genes?

1. Can viruses be used to change or alter our genes?

Yes, viruses can be used as a tool to change or alter our genes. This process is known as gene therapy, where viruses are used to deliver specific genetic material into our cells in order to correct or replace faulty genes.

2. How can viruses be used to diminish the effects of genes?

Viruses can be used to diminish the effects of genes by targeting and altering specific genes that are causing a disease or disorder. This can be done through gene editing techniques or by introducing new, healthy genes into the affected cells.

3. Are there any risks associated with using viruses to modify our genes?

Yes, there are potential risks associated with using viruses for gene therapy. These can include immune reactions, unintended changes to other genes, or the possibility of the virus being transmitted to others. However, extensive research and safety protocols are in place to minimize these risks.

4. What diseases or disorders can be treated with gene therapy using viruses?

Gene therapy using viruses has shown promising results in treating a variety of diseases and disorders, including genetic disorders such as cystic fibrosis and hemophilia, as well as certain types of cancer and inherited eye diseases.

5. Is gene therapy using viruses currently available for use in humans?

Yes, gene therapy using viruses has been approved for use in humans by regulatory agencies in several countries. However, it is still a relatively new and developing field, and its use is currently limited to certain conditions and in specialized medical settings.
