Antigens are substances that incite your immune system to respond by producing antibodies. They include both foreign substances, such as pollen, and substances made by the body. Ones made by the body are non harmful.
An antigen is a substance that can trigger an immune response in the body, such as proteins on the surface of bacteria or viruses. A pathogen, on the other hand, is a type of antigen that can cause disease in the host organism by invading and damaging tissues. Not all antigens are pathogens, but all pathogens are antigens.
Antigen. An antigen is a small piece of a pathogen, such as a virus or bacteria, that triggers the immune system to produce antibodies to fight off the infection. This immune response helps protect the body from further exposure to the pathogen in the future.
To help immune cells identify and destroy a pathogen
Antigen
c. a pathogen makes more than one antigen. Pathogens typically have multiple epitopes that can be recognized by antibodies, but they do not make more than one antigen. Each pathogen produces specific antigens that can trigger an immune response.
An Antibody.
An Antibody.
Basically to explain this, an antigen is any type of pathogen that causes disease, while an antibody is something that combats against the antigen.
do you mean antigens? An antigen is any (foreign) substance that stimulates an immune reaction.
If it can be harmful, it can be referred to as pathogen.
A substance that contains the antigen of a pathogen is known as a vaccine. Vaccines are designed to stimulate the immune system by introducing a harmless form or component of the pathogen, such as proteins or inactivated viruses. This exposure helps the body recognize and mount an immune response against the pathogen if encountered in the future, providing immunity.
An antigen is a body's system for creating antibodies to fight infection. A pathogen is an infectious agent (or germ).
