Immunology allergy

Allergic reactions are caused by degranulation of basophils, the release of biologically active substances, histamine

If you think about autoimmune disease, it is really like this!

Yeah, I mean, why does our immune system sometimes perceive harmless substances as dangerous to the body and starts to fight them?

@elizaveta-msu The answer can be simple - due to evolutional development. If your organism does not fight, then you give a chance for some bacteria/virus/alien substance harm your body.

@morphism Are there any preventive measures against allergies? Something like an "allergy vaccine" in childhood, for example? I understand, it sounds incredible, because there are a lot of potential allergens, but..

@elizaveta-msu There are so-called "allergy shots": regular injections over a period of time, generally around three to five years to stop or reduce allergy attacks. You may want to consider allergy shots if you have symptoms more than 3 months a year and medicines don’t give you enough relief.

@morphism In fact, this shows the imperfection of the immune system, since this is a pathological reaction.

@argentum Ofc, nothing is perfect. The system is tuned to specific things and every new one is like disturbance

@argentum you mean e.g. this? https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6585781/  

@morphism Yes, as an example this article

@morphism just allergic reactions can be purely physical effects, such as the sun

@argentum in this case I think this is a definitely an error 

@morphism me too
