Okay, kiddo, let's talk about something called cytokine redundancy. You know how when you're drawing a picture and you use different colored crayons to make it look nice and bright? Well, in our body, we have something called cytokines that work like colored crayons to help our immune system fight off bad things like germs and viruses.
But sometimes we have too many cytokines, and they start overlapping or doing the same job. It's like having too many red crayons and not enough blue or green ones. This can lead to problems because instead of helping our immune system, these extra cytokines can actually cause inflammation and damage to our body.
So scientists are working to figure out which cytokines are important for fighting different diseases and which ones we don't need as much. This way, we can make sure our immune system is using the right "colored crayons" to stay healthy and strong.
