Study Notes
Immunology 2
- Module: Biomedical Sciences
- Tutor: Ms. P. Lazarou
- Learning Outcomes:
- Apply dental therapy and hygiene principles derived from biomedical, behavioural, and materials sciences.
- Develop knowledge in immunology.
Assessment
- Formative: Quiz
- Summative: Questions integrated into Biomedical Sciences assessment.
Immunology 2 - Specific Tasks
- Task 1: Read and complete a task from the article "Antibody-mediated vs cell-mediated immunity," pages 5-8. Article authors are referenced.
- Task 2: Complete a self-assessment quiz on antibody-mediated and cell-mediated immunity.
Intended Learning Outcomes
- Review antibody-mediated and cell-mediated immunity using resources and a self-assessment quiz.
- Define and recognize differences between antibody-mediated and cell-mediated immunity.
- Understand and explain passive and active immunization.
Antibody-mediated and Cell-mediated Immunity
- Consolidation of learning is required.
- Two YouTube videos linked as resources are included:
- The Cellular Immune Response
- Antigen Processing and Presentation
Humoral and Cellular Immunity
- Diagrams illustrating humoral and cellular immunity are presented.
- Humoral immunity involves extracellular microbes and B lymphocytes, resulting in antibody secretion and functions like neutralization, lysis, and phagocytosis.
- Cellular immunity targets intracellular microbes (e.g. viruses) involving antigen-presenting cells, T cells, and subsequent cytokine release, leading to the lysis of infected cells.
Passive and Active Immunity
- Passive immunity:
- Natural passive: e.g., mother's antibodies through placenta/breast milk.
- Artificial passive: transferring antibodies therapeutically (e.g., snake antitoxin, immunoglobulin).
- Active immunity:
- Natural active: developing antibodies from infection.
- Artificial active: developing antibodies from vaccination.
- Transfer of antibodies/sensitised cells from an immune person to a non-immune person. This is short-term and risky if own response is not developed.
- Production of antibodies against a specific antigen after exposure. Memory is developed.
Immunisation
- Artificial active immunity: antibodies develop after immunization/vaccination.
- Immunological memory and development of a stronger immune response to subsequent infections.
- Antibodies attach to specific surface structures on the antigen to activate the complement system.
How Vaccines Work
- A small amount of a harmless form of a disease is introduced to the body.
- The body produces antibodies to fight it off.
- If the disease reappears, the antibodies are already present to prevent infection.
References
- Articles and resources on immunology, immunopathology, and allergy from various websites and publications are listed.
