> I think if this worked as intended, no additional treatment is required. It is correct if the therapy is targeting all stem cells. I have not understood clearly from the article but it seems the treatement is targeting "living cells". Once all your 'fixed' cells have been renewed you would need another round of treatement.

I have Haemophilia A, I was actually offered a place on an earlier trial although I didn't do it. It was explained to me that you would not need further gene treatments even though it targeted adult cells. I think most cells are made by mitosis and don't come from stem cells. Here's a screenshot of the explanation I received when I was invited on the trial - https://i.imgur.com/H329Vgv.jpg > "By using BMN 270 to prov…

Thanks for clarifying my misconceptions !

I’ve heard reports that changing out a microbiome has resulted in a few bald people regrowing their hair.

Thanks for sharing! Can I ask what considerations went into your decision? Will you be pursuing this now that there is more evidence that it's effective?

What a fantastic gateway to show how gene therapy can completely resolve diseases. Many diseases are as simple as your eyes being brown vs blue - you simply have or lack particular proteins. I couldn’t find it on a cursory reading, does anyone know what vector they used to achieve liver sinusoidal cell specificity? My understanding is that many gene therapy studies have used blood cells, which can be pulled out of th…

Many diseases are as simple as your eyes being brown vs blue - you simply have or lack particular proteins.

I wish it were that simple. :(

Eye color, for example, is influenced by a combination of multiple genes. There’s no straightforward eye color gene. Likewise, it’s especially true for diseases when something like “stomach cancer” is actually a dozen different diseases where each is influenced by dozens of different genes that share symptoms. Combinatorial explosion is a real problem.

I hope they can expand this to other genetic problems. There are hundreds of genetic issues science knows about. Just off the top of my head I can think of high cholesterol, cystic fibrous, and sickle cell anemia. I know there are others, but I'm just a layman not a medical doctor. Those who have any of the above would like to be cured.

There is a pretty strong argument that Haemophilia is the disease that has had the biggest impact on the last 100 years. Russian heir to the throne Alexis Romanov inherited the disease and his suffering and lack of treatment options destabilized his family and contributed to leadership issues culminating in Russian defeat in WW1 and the Russian revolution and the rise of the Soviet Union. Agree? If not, what disease…

I'd argue the Bolshevik revolution would still have happened even if Romanov wasn't a hemophiliac. I don't see how the child's disease would have affected the management of the Russian supply lines in WWI, or have caused the February Revolution.

The plague in Europe. And in North America, smallpox, which decimated (and more) indigenous peoples.

Neither of which occurred in the last 100 years.

Just to be extra pedantic, and not in a serious way, the 1917 Russian October Revolution, was neither in the last 100 years since we are in December.

I mean, obviously I regret it now, but at the time I had no idea it would work. I'm sure the next trial will be extremely oversubscribed! I think my trial was actually for a low dose version to test safety of the vector and it didn't have any clinical effects.

Its quite incredible though, there's only a few thousand people in the UK with haemophilia - this trial just cured like 0.5% of them
