Antigens are molecules that are capable of inducing an immune response in the body. They can be proteins, polysaccharides, lipids, or nucleic acids that are recognized by the immune system as foreign invaders.
Types of Antigens
There are two main types of antigens: foreign antigens and self-antigens. Foreign antigens come from outside the body, such as viruses, bacteria, and other pathogens. Self-antigens, on the other hand, are molecules that are derived from the body's own cells.
Role of Antigens in Immune Response
When antigens enter the body, they are recognized by immune cells called lymphocytes. These lymphocytes then produce antibodies that bind to the antigens and mark them for destruction by other immune cells. This process is crucial for protecting the body against infections and diseases.
Antigen Presenting Cells
Antigen presenting cells (APCs) are a type of immune cell that engulf foreign antigens and present them to lymphocytes. This presentation helps activate the lymphocytes and initiate an immune response against the invading pathogens.
Antibodies are proteins produced by the immune system in response to antigens. They help neutralize pathogens and mark them for destruction.
Immune system plays a crucial role in recognizing and responding to antigens, thereby protecting the body from infections and diseases.
Antigenes Examples
- The antigenes in the bloodstream triggered an immune response.
- The doctor is running tests to identify specific antigenes in the patient's body.
- Vaccines are designed to stimulate the production of antibodies by introducing harmless antigenes.
- Different strains of the flu virus have varying antigenes on their surfaces.
- Antigenes play a crucial role in activating the body's defense mechanisms against pathogens.
- The immune system can recognize and respond to foreign antigenes to protect the body from infection.
- Cancer cells can sometimes evade detection by the immune system due to a lack of specific antigenes.
- Autoimmune diseases occur when the immune system mistakenly attacks the body's own antigenes.
- Researchers are studying how to manipulate antigenes to improve the effectiveness of immunotherapy treatments.
- Antigenes are unique markers that help the immune system distinguish between self and non-self molecules.
