Study Notes
Antigens
- Antigens are foreign molecules that trigger an immune response.
- Examples include pollen, bacteria, viruses.
- Antigens are located on the surface of pathogens.
Immune Response (Challenge and Response)
- Challenge: Antigens on pathogens invading the body.
- Response: Ingestion of the pathogen by a macrophage.
Helper T Cells vs. B Cells
- Helper T Cells: Activate immune cells using cytokines.
- B Cells: Produce antibodies.
Clonal Selection
- Clonal selection is the body's process of producing B and T cells to target specific pathogens.
- These cells identify and respond to specific pathogens.
Immunity
- Immunity is the body's ability to fight off infections and harmful substances.
- Recognizing and neutralizing pathogens or toxins is part of immunity.
- Passive Immunity: Transfer of antibodies.
- Active Immunity: Production of antibodies after exposure to antigens (e.g., vaccines or infection).
Zoonosis
- Zoonosis is the transmission of diseases from animals to humans, caused by pathogens (bacteria, viruses, or parasites).
- Examples include COVID-19, bird flu.
Zoonotic vs. Non-Zoonotic Diseases
- Zoonotic: Rabies, Ebola
- Non-Zoonotic: Diabetes, Cancer
Allergic Symptoms
- Allergic symptoms can be caused by histamines.
Smallpox
- Smallpox is a disease.
