antígeno

🧠 What does antígeno mean?

An antigen is a substance that induces an immune response in the body, typically producing antibodies. In medical contexts, it refers to foreign substances like bacteria, viruses, or foreign proteins that are recognized by the immune system as a threat. The presence of antigens often triggers the production of specific antibodies to neutralize them. This concept is fundamental in immunology and is applied in areas such as vaccination and diagnostic testing.
