In December, I attended the Cell Symposium on type 2 immunity (i.e. our adaptive immune system as opposed to innate defence mechanims) and learned a lot about the big two questions in the field of allergy, namely why did allergies evolve, and why are they becoming more prevalent in industrialised societies?
It's been a steep learning curve not helped by immunologists' habit of speaking in acronyms, but I believe I discovered some meaningful connections to evolution and ecology - it's really all about snakes and parasitic worms. So I wrote a feature summarising what I think I understood, which is out today:
Why did evolution give us allergies?
