Flashcards
Antibody-mediated immunity
Antibody-mediated immunity
Immune responses that involve antibodies in blood and lymph to target and neutralize pathogens. This involves B cells differentiating into plasma cells that secrete antibodies.
Cell-mediated immunity
Cell-mediated immunity
Immune responses that directly involve T cells to kill infected cells or activate other immune components. Primarily involves cytotoxic T lymphocytes (CTLs) and helper T cells.
Active immunity
Active immunity
The body's natural immune response to an antigen, resulting in the development of antibodies. This can occur through infection or vaccination.

Study Notes
Immunology 2 Module
- Module is part of Biomedical Sciences
- Tutor is Ms P Lazarou
- Subject is focused on applying biomedical, behavioural, and material science principles to dental therapy and hygiene practices
- Aims to develop knowledge and understanding of immunology
- Learning outcomes include reviewing antibody-mediated and cell-mediated immunity, defining differences between the two types, and understanding passive and active immunization
Assessment
- Formative assessment includes a quiz
- Summative assessment involves questions integrated into the Biomedical Sciences eAssessment
Immunology 2: Tasks
- Task 1: Read and complete a task on an article about antibody-mediated vs cell-mediated immunity (pages 5-8)
- Task 2: Complete a self-assessment quiz on antibody-mediated and cell-mediated immunity
Intended Learning Outcomes
- Review antibody-mediated and cell-mediated immunity by using resources and completing a self-assessment quiz
- Define and understand variances between antibody-mediated and cell-mediated immunity
- Recognise and explain passive and active immunizations
Antibody-mediated and Cell-mediated Immunity - Consolidation
- The Cellular Immune Response (YouTube link included)
- Antigen Processing and Presentation (YouTube link included)
Humoral vs Cellular Immunity
- Diagrams showing differences in processes (Humoral and Cellular Immunity)
- Humoral: extracellular microbes, B-lymphocytes, antibody secretion (neutralization, lysis(complement), phagocytosis)
- Cellular: intracellular microbes, antigen presenting cell, helper T cells, T cell receptor, proliferation of effectors cells, lysis of infected cells
Passive and Active Immunity
- Natural passive immunity: mother's antibodies via placenta/breast milk
- Artificial passive immunity: transfer of antibodies (e.g., snake antitoxin, immunoglobulin)
- Natural active immunity: antibodies developed in response to infections
- Artificial active immunity: antibodies developed through vaccinations
- Transfer of antibodies/sensitized cells from immune person to non-immune person; Short duration of protection; Risk of loss of immunity
- Used when risk of infection is high/patient cannot generate their own immunity
Immunisation
- Artificial Active Immunity: antibodies developed after immunization/vaccine administration
- Immunological memory: a specific immune reaction induced against a weakened/killed microorganism; subsequent infections trigger a stronger and faster immune response via antibodies and/or cells; antibodies attach to antigens activating complement system
How Vaccines Work
- Small amount of harmless form of a disease is introduced
- Body produces antibodies to fight the introduced harmless form
- If the real disease is encountered, the body already has the antibodies and is immune
