Immunoglobulin E
Okay kiddo, have you ever heard of allergies? They make you sneeze, cough, and feel not so great. Well, immunoglobulin E (IgE) is a type of protein that our immune system makes when we have allergies.
Think of IgE as an alarm signal that tells our immune system that something isn't right. When we breathe in or touch something that we're allergic to, like pollen or cat hair, our body makes IgE. The IgE then attaches to cells called mast cells and basophils, kind of like a key fits into a lock.
Once the IgE is attached, those cells release chemicals like histamine that try to fight off the allergen. This causes symptoms like itching, sneezing, and swelling. It's like the cells are trying to sound the alarm and tell our body "hey, there's something bad in here, we need to get rid of it!"
So while IgE helps us fight off allergens, it can also make us feel pretty crummy if we have an allergy. But don't worry, there are ways to manage allergies and feel better.
