When the immune system fails to recognize self and destroys its own tissues what is this?
The medical term for the immune system failing to recognize its own body tissue and attacking its owner's body is autoimmunity. Common examples of autoimmune disorder are (a) Rheumatoid arthritis and (b) systemic lupus erythematosus ("lupus")
Why is it important for immune-system cells to be able to recognize all of the body's own cell?
Think about it for a second. If you lead an army into battle, and your own army start to shoot each other, what odds do you have of winning against the oposition? If the body starts to kill it's own cells that may be used to kill pathogens, it is immediately weakened
What happens when the body cannot differentiate between pathogens and body cells?
The immune system will target the body's own cells
Why is it important for immune system cells to be able to recognize all of the body's own cells?
This happens to my Mom sometimes. When she's really stressed, tired, sick, etc; her immune system starts attacking her body again. I don't know why, it just does. It happened with her immune system or something like that and also her eyes. The immune System needs to know what is friendly and a threat to the brain & body. Although it has trouble sometimes when you get a transplant and the shape/size/composition/etc isn't similar enough to your own.
How does your body know which cells to attack?
1. Your immune system can recognize cells based on the proteins present on the surface of cells. Viruses, bacteria, and other foreign cells are recognized as being different from your own cells and are attacked by your immune system.
What is immume and its function?
Immune system is an essential for all living organisms. In bodies immunity system helps to protect the body from harmful diseases. Vitamins , carbohydrates are essential to boost immune system in a body.
What produces an autoimmune response?

What cell surface molecule is a major agent in tissue rejection?
Class I and II MHC molecules are what the body uses to recognize it's own cells as "self". If it detects an antigen (anything foreign to the body) the immune system will trigger a response.
What is a autoimmue disorder?
An illness that occurs when the body tissues are attacked by its own immune system.
What is One example of the immune system attacking the body?
One example of the immune system attacking the body is autoimmune diseases, such as rheumatoid arthritis. In this condition, the immune system mistakenly targets and attacks the joints, leading to inflammation, pain, and potential joint damage. This occurs when the immune system fails to distinguish between foreign invaders and the body’s own tissues, resulting in self-destructive immune responses.
How do people get sarcoidosis?
The body's immune system normally fights off infections by releasing white blood cells into the blood to isolate and destroy the germs. This results in inflammation (swelling and redness) of the body tissues in that area. The immune system responds like this to anything in the blood it doesn't recognize, and dies down when the infection has been cleared. It is thought that sarcoidosis happens because the immune system has gone into "overdrive", where the body starts to attack its own tissues and organs. The resulting inflammation then causes granulomas to develop in the organs.
