This will likely not be an impediment to treatments based on CRISPR. The study has been available in preprint form for ~6 months on biorxiv [0]. At least some of the companies researching CRISPR were aware of this issue at the time the paper was released. It has since been mitigated, as specified at the bottom of the article.

It's really amazing that humanity is at the stage where we're intentionally evading our own immunity to bacterial components so we can repurpose the components to help ourselves.

but it's a bit sad that it can't intentionally help it to handle cancer.

I think this is obvious to anyone familiar with bacteria and immunity. The headlines will go for the 'CRISPR is dead" angle, but the work arounds are simple and relatively easy to implement. I think the article is still extremely valuable. It shows that, yes, we target CRISPR just like any other microbiome protein hanging out in a mucus membrane. But it also shows that it's not a threat (or an indicator of a threat).

Yet.

By the way, "cancer" is a class of diseases, not a single disease to treat, and many of them currently have CRISPR-derived treatments being actively developed.

With desktop gene sequencers becoming a near commodity product I’m not so sure. There are a companies that currently focus on this area specifically by leveraging the ever dropping costs and capabilities of gene sequencing by developing targeted immunotherapy solutions that can target the specific genetic makeup of a tumor from a biopsy.

This is all based on the assumption that our understanding of in vivo processes is as good as our understanding of in silico processes. It isn't. Not even close.

But that's also true for mainstream/existing therapies.

CRISPR holds way more promise than silly fantasies of human genetic enhancement. The most exciting and practical uses for it apply to challenging everyday problems: food, energy, invasive species, biodiversity. Besides, the ethical problems with experimenting on human beings are extremely intractable.

> CRISPR holds way more promise than silly fantasies of human genetic enhancement I really dislike pandering, dismissive statements like this.

I'm not sure how to interpret this - are you saying we should use CRISPR to make people think a certain way? If so this seems like a pretty horrific suggestion.

How is a CRISPR trial on a terminal patient any different than another experimental medical trial on that same terminal patient?

I agree. My father has terminal cancer and has been practically banging down doors to try to get onto medical trials for new experimental treatments. If other people in his position want to do the same thing then who are we to judge?

Humans are, for example, very poor at making risk assessments. Evolution has "programmed" our brains to focus too much on certain things and not enough on others. These heuristics might have made sense in ancestral environments bit are quite harmful in today's world. Evolution has already "made us think a certain way". Why would it be so horrific to, for example, lessen certain of those tendancies, if they are harmful?

So to the non-geneticist noobs (like me), is it correct to interpret this finding as suggesting that the promises of CRISPR may be dead in the water? Does this mean all the hype was nothing more than hype? Should anyone with investments in CRISPR be seriously looking at dumping their stock? Should anyone who was holding out on CRISPR to give us super powers / cure disease / etc start drinking copious amounts of alcoh…

What the layman thinks of genetic engineering magic is going to have to happen in the germline. That means it's not going to help you or me or anyone else already alive.

This is true for most genetic engineering applications but not all. Somatic gene therapy has been successfully performed in a few cases. There will almost certainly be more applications in the future, and it’s reasonable to expect that they will be able to handle some prevalent diseases (such as all types of diabetes).

Anything as powerful as CRISPR will most likely be misused and have a very high error rate/unexpected consequences initially anyway: https://labiotech.eu/medical/crispr-therapy-cancer-risk/ CRISPR is definitely going to go through the "hype cycle" - as in the hype will die out long before we can prove it can be safely used in humans, and these achievements will likely happen in the background over several decades tim…

The difference between CRISPR and many other overhyped technologies is that CRISPR has already proven its mettle. It’s being used productively daily in labs across the world and has lowered the cost of performing many experiments, or even made new experiments possible in the first place.

You’re right that there’s a certain amount of hype surrounding CRISPR, especially when it comes to potential medical application (whether this works remains to be seen, although I and most people in the field remain optimistic). But until something even better comes along I don’t think interest in CRISPR will die down soon.
