Antigen
Q1: How can you define an antigen?
Answer:
An antigen is any foreign substance that comes inside our body or sometimes our own body’s substances that have the capability to induce an immune response in our body.
Q2: What do you call the substance that is produced by our immune system in response to the antigen?
Answer:
The substance that is produced by our body in response to antigenic stimulation is called the antibodies or the magic bullet of our immune system.
Q3: What do you call the study of antigens, antibodies, and the system associated with them?
Answer:
The branch of biology that deals with the study of antigens, antibodies, and the whole system of immune system is called immunology.
Q4: Give one example of acquired immunity that is used to fight antigens or pathogens.
Answer:
Acquired immunity is something that is acquired throughout our life like vaccines.
Q5: What do you understand by the term immunogenicity?
Answer:
Immunogenicity can be defined as the ability of an antigen to induce a specific immune response in the body of a vertebrate host.
What is an Antigen?
Antigen is a substance that can trigger an immune response in the body. It is typically a foreign substance, such as a microorganism, a toxin, or a particle, that the immune system recognizes as being “non-self” and potentially harmful. When the immune system encounters an antigen, it produces specific proteins called antibodies that can recognize and neutralize the antigen, or stimulate other immune cells to attack and destroy it
