Why it is important for body to recognize its own cells?
So that rejection does not occur.
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
How do T cells contribute to the development of autoimmune diseases?
T cells play a key role in autoimmune diseases by mistakenly attacking the body's own cells and tissues. This can happen when T cells become overactive or fail to recognize the body's own cells as "self," leading to inflammation and damage to healthy tissues.
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 the immune system recognize its own body?
By recognizing self from non-self. Every cell in the body carries specific protein markers that are recognized by all immune cells so they do not attack self, at least when the system is operating well.
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 happens when the body cannot differentiate between pathogens and body cells?
The immune system will target the body's own cells
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.
Disease in which body attacks its own cells?
macrophage
Lack of reactivity of T cells and B cells to your own proteins is know as what?
The lack of reactivity of T cells and B cells to your own proteins is known as self-tolerance. It is an important mechanism to prevent the immune system from attacking the body's own tissues. If self-tolerance is disrupted, it can lead to autoimmune diseases.
How does the 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.
Where do the antibodies come from when a person is vaccinated?
Own body cells.
