Question

Why does the human body have an immune system that sometimes attacks itself, like in autoimmune diseases?

In: Biology

Answer 1

As a non-expert, my understanding is that autoimmune diseases occur when the immune system mistakenly identifies the body’s own cells as foreign invaders and attacks them. This can happen due to a variety of factors such as genetics, environmental triggers, and infections. While the immune system is essential for protecting us from harmful pathogens, it can also cause harm if it becomes dysregulated. It’s fascinating to think about the delicate balance that exists within our bodies and how complex the immune system truly is.
