Feng Zheng is starting a company called Beam Therapeutics that’s going to focus on even more precise CRISPR. Please see the link below. There are many more articles if you google Beam Therapeutics.

Cool but will they be doing any herpes research?

@Taintedgirl

They have not stated what they will be working on yet. Don’t be discouraged by that, this company is very serious. They got $87 million in series A funding.  Feng Zhang who has been a huge part of CRISPR.  I’ve edited the original post that includes their website. 

I am not a scientist but maybe someone else can elaborate from what I quoted from Beams website below.  It seems that if they are able to more precisely edit the genome it’s better news for HSV

Beam Therapeutics website - Science section. 

Our groundbreaking CRISPR base editing technology allows us to make permanent, specific edits to single bases in DNA and RNA. Base editor therapeutics represent a new class of “precision genetic medicines,” combining precision targeting of the genome with precision control of editing outcomes.

They probably won’t have anything to do with hsv

I didn't see any disease mentioned in their website either, but that's likely because Beam is just getting started. The website says they are still recruiting for various management positions. Let's hope the work of Beam, Excision, Editas, and others will soon lead to cures of HIV and HSV. But it's hard to predict when a Eureka moment will occur.

Essentially, nucleotides are the letters in the DNA - they are also the N in DNA. They have to be paired as follows: A  with T, and C with G. 

There are many human genetic diseases that are the result of a mis-pairing of these nucleotides, such that we need to snip out one nucleotide. Consequently, the cell's innate DNA repair mechanisms will kick in (and hopefully provide the correct pairing).

Formerly, CRISPR could only be programmed to remove a chunk of DNA, and so it would have to remove at least one of these pairings per snip. 
The new method described in the link above moved beyond that limitation, allowing a single letter to be removed precisely.

In essence, this is as selective & fine as you can possibly get in editing DNA.

Very cool! Thank you for explaining.

We hope that they can pay attention to the disturbing disease of hsv. If there are strong friends, they can go and visit them. I believe that if there are a large number of people, they will be willing to research and develop. In the United States, 20% of people have hsv2. 90% of people in China carry hsv1, and about 30 million people carry hsv2. This market is very commercially valuable.

I would guess Cancer will be the main target initially. CRISPR has previously been tried on 3 viruses including hsv so they are already thinking about it. This is very promising but still difficult to give a timeframe. HSV is especially difficult because it hides in neurons. Google  “ can CRISPR cure hsv?” I think article was from 2016.. I’m very hopeful!!

Whatever Editas Medicine has I can guarantee it’s more advanced than what Excision has developed.

Excision is using the ICP0 gene editing which only reduces replication by 60-90%. Editas publishes papers on the same findings, but went on to find other genes that could be edited to “eradicate” the virus. 

I know Excision is in animal trials now, with human trials expected in 2019-2020 with nanotechnology for delivery. But that product is based on ICP0 only.

Beam will likely be the one to take this to the next level, but will likely be a couple of years behind Excision at bringing a product to market.

You guarantee it? Based on what? Have you studied both approaches to make this statement?

Excision is NOT using just the ICPO gene editing, they are using ICPO, ICP4, ICP27. From one of their research papers on their website, they say the following:

"Combined treatment of cells with CRISPR targeting ICP0 plus the immediate early viral proteins, ICP4 or ICP27, completely abrogated HSV-1 infection"

Thanks for the additional info. I didn’t know Excision had already gotten so far. 

I guess we can hope that Editas/Beam have gone even further in their research, but I have nothing to confirm that other than timelines of press releases.

      Lol, a thousand guinea pigs.  I think you raise a good question (though it's a bit sad that a 1000 guinea pigs might have to die). But every every preclinical study I know, also uses a fairly small number of lab animals.  It's rarely more than a few dozen.  For example, the EDITAS proof of concept ocular herpes solution tested in 36 animals, of which some got placebo, and some got AAV with no editors.  So testing in only a handful of animals seems to be the norm.  So I wouldn't read into that caveat too much, if I were you.  But whether that vaccine can ever enter human trials, that I don't know.   Some things I've read seemed to suggest that ppl are kind of down on the idea of testing vaccines, on account of the failures.  I hope that's not the case.

      Yeah @Lukeherpwalker I agree. Many people just see the igg tests and listen to random internet strangers about their results being from a childhood infection and on their mouth.  The fact is I got genital herpes because someone didn’t want to believe their HSV1 was genital when it was. Blood tests never can tell you location. Fact. Let’s deal with facts instead of highly unsupported opinions in the name of a life long virus shall we?

      hi Imsu, No problem about the questions.  Sangamo is a research stage stem cell and gene editing company.  They currently are not researching HSV.  But they have a gene editing and stem cell stage 1/2 trials going on regarding HIV.  The gene editing solution they are using is zinc fingers. https://www.sangamo.com/pipeline/partnered-programs And no problem about your questions.  Feel free to also inbox me if you like and want to continue the conversation.  I'm not an expert, but I've done my research.  Cheers.

      I’m more than sure you got it from your current boyfriend. 5 days later and you have an outbreak in the anal where you did it for the first time. I had a vaginal outbreak 5 days after unprotected sex with my ex. I knew I was from him because of the negative tests I had during my outbreak. Unfortunately he was i denial about the situation and didn’t support me at all. Your boyfriend may not have been aware that he had it. And he may also lie about it if he finds out he actually does carry the virus. Hopefully he gets tested and things get sorted out for the both of you.

      If you are having genital symptoms. . and test positive for hsv1 its very relevant. Op may indeed have ghsv1
