Study Notes
Immune Response
- The adaptive immune response, also known as the specific immune response, recognizes when a pathogen is present.
Antigens
- Antigens are substances, such as proteins, carbohydrates, or other molecules, that can trigger an immune response, causing the production of antibodies.
Leukocyte Recognition
- Leukocytes, also known as white blood cells, recognize when a pathogen is present through the recognition of antigens on the surface of the pathogen.
Immune Response Specificity
- The specificity of the immune response is determined by the shape and chemical properties of the antigen, which allows the immune system to distinguish between different pathogens.
Antigens on Human Cells
- Antigens are not typically present on human cells, as they are typically recognized as "self" by the immune system, and do not trigger an immune response.
