Antigen

Any foreign molecule that can trigger an immune response. Examples include pollen, bacteria, and viruses.

Clonal Selection

The process in which the immune system identifies specific pathogens and produces B and T cells to fight them.

Immunity

The body's ability to resist or fight off infections, diseases, or harmful substances.

Passive Immunity

The transfer of antibodies from one individual to another, providing immediate, temporary protection.

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.
