How is the immune system involved with atopic dermatitis?

I have a question. I heard that the immune system is involved with eczema. Is that true? And also, how does that work?

Thanks so much for asking this question. It's a good one. Essentially, people with Atopic Dermatitis, or AD,

often have a sensitive immune system. Now, your immune system is what fights off the things that make you sick.
