When the immune system does not respond to a particular antigen?
Tolerance exists when the immune system does not respond to a particular antigen. All cells and tissues in the body contain antigens that normally do not stimulate an immune response. The immune system is said to exhibit tolerance toward such antigens.
What is the term used to describe if a patient has ever had contact with a particular antigen?
The term used to describe if a patient has ever had contact with a particular antigen is "sensitization." Sensitization occurs when the immune system has been exposed to and recognized a specific antigen, leading to an immune response upon subsequent contact with the same antigen.
What is a particulate antigen?
A particulate antigen is a type of antigen that consists of particles, such as viruses, bacteria, or other microbial components. These particles can induce an immune response by being recognized by immune cells, leading to the production of antibodies and activation of immune defenses. Particulate antigens are often used in vaccines to stimulate a strong and targeted immune response.
What is the molecule that can be recognized by the immune system?
Antigens.
What system does antigen belong to?
Antigen is a component of the immune system. It can trigger an immune response in the body by interacting with antibodies or immune cells.
What is antigene and antibody?
An antigen is a substance that can invoke an immune response. While an antibody is the immune system's response to an antigen. Antibodies, act by directly neutralizing the antigen and/or bind to the antigen and signaling marcophages to phagocytose the antigen.
What term describes the overaction of the body to a particular antigen?
Allergies develop when the body overreacts to an antigen.
What causes the immune response?
an antigen
What is a substance that causes an immune response called?
Antigen
Is the immune response triggered by antibodies?
No. Immune response is triggered by the antigen.
What does the body do when an antigen enters the body?
when a antigen enters the body then the body would send antibodies to get rid of them. The antibody doesn't get rid of the antigen they tag it by binding to it so that a cell..a white blood cell can come and destroy by phagi.
What is the first step of the immune response?
antigen
