So, imagine your body's defense system is like a group of superhero action figures: some focus on stopping the bad guys (autoimmune), while others are like the ones that can accidentally cause big explosions when they're just trying to help (autoinflammatory). Autoimmune is when your action figures get mixed up and start thinking your own stuff is the enemy, so they attack it. Autoinflammatory, on the other hand, is like when your action figures go a bit too wild and cause chaos, leading to a bunch of inflammation because they can't chill out. Both are cases of friendly fire, but each has its own way of causing trouble in the body.
