No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

DISCLAIMER: I am in no way advocating for the spreading of a highly contagious and deadly disease or the abstention from safe and highly effective vaccines. But, this is No Stupid Questions, so…

Measles is known for wiping out your immune system memory and re-endangering you to pathogens you had once successfully fought off.

Allergies are when your immune system misidentifies something harmless (like pollen or peanuts) as a harmful pathogen and triggers an immune response.

So, what happens to allergies in people who get measles? Does it wipe out the immune system’s memory of the allergen? Does it expose them to develop new allergies? Do we even know whether it does anything to allergies at all, or has it never been studied? What about other auto immune diseases?

Secondly, if it does do something, is there some way that it can be utilized to help allergy sufferers? Not in the “give people a deadly contagious disease” kind of way (I’ve heard of the tapeworm thing), but is there something there that could studied and developed into a targeted drug or treatment? Or is the mechanism just too broad and dangerous.

That's a really interesting question. I have no idea, but I'd be interested to read what someone with relevant knowledge had to say about it.

That's a fun question to ponder. I don't have a good answer for you. I think it might boil down to the mast cells and whether or not measles kills them in addition to the B and T memory cells. Have you read Immune by Philipp Dettmer yet? If not, you absolutely should check it out. There's an excellent chapter about allergies, as well as a subchapter about measles.

Edit: trying to harness this measles' indiscriminate appetite for long-lived plasma and Memory B and T cells to only those that may be sensitive to allergens seems like a tall order, but it's amazing what immunologists have been able to achieve.

Maybe figure out how to make a measles virus with an antigen that's only similar to the allergen's so it selectively attacks those problematic immune cells. That'd be neat. Sounds REALLY complex in practice.

So, disclaimer. Not a doctor, a microbiologist, a virologist, or anything with actual first hand knowledge. So, keep a salt shaker handy to take this with.

Since worm boy has started running his mouth, I've been casually reading about measles. Just enough that when some idiot echoes him that I can feel comfortable telling them to STFU and GTFO and not wasting my time trying to argue with them. So that's kind of a second disclaimer, I guess, that I haven't read every single line of every single publication out there.

That being said, nah. There have been patients with measles that also had preexisting allergies, and it didn't get rid of them. At best, they were suppressed a little during the illness.

So far, attempts along those lines on purpose haven't worked to an extent that it's worth it. There was some testing done with other means of destroying the relevant immune cells, and the most effect was a temporary reduction in severity of allergic response. They eventually came back in full.

So, assuming you want to cite a rando on the internet, if anyone starts spewing that tripe as a benefit, you can confidently tell them that I said to STFU and GTFO.

I don't know anything about it but I found these 2 articles using google scholar that seem relevant:
