Scientists have recently done research that suggest disabling a gene that codes for a protein could cause the development of a cure for the common cold. The problem with the common cold is that it quickly becomes drug resistant since viruses mutate and become drug resistant quickly. They tested that SETD3 was a common protein extracted from infected cells. So they engineered mice that didn't have the protein. After injected with the virus, the mice did not get infected. But removing the gene that produced SETD3 had consequences. SETD3 is involved in muscle contractions, so the mice could not give birth without assistance. Due to this, scientists have started research on a drug that stops the protein from interacting with the virus, but it is still many years off.
In my opinion, this a huge development in the cure for the common cold. I feel it points in the right direction in terms of finding a permanent cure. Obviously, killing the viruses isn't working anymore, so we have to find more intuitive ways to stop infection. I feel this could be the intuition and creativity we need to find a permanent cure.
