Immunology 2 Tutor: Ms P Lazarou Module: Biomedical Sciences GDC Learning Outcomes The aim of this subject is to apply to the practice of dental therapy and dental hygiene principles that derive from the biomedical, behavioural and materials sciences. To develop knowledge in the study of immunology. GDC 1.1 Assessment Formative Summative Quiz Questions incorporated in Biomedical Sciences Eassessment 4 Immunology 2 1) Read and complete task on the following article, pages 5-8 from Antibody- mediated vs cell-mediate immunity: An introduction to immunology and immunopathology Richard Warrington1*, Wade Watson2 , Harold L Kim3,4, Francesca Romana Antonetti5 2) Complete the self-assessment quiz on the antibody mediated and cell mediated immunity 5 Intended Learning outcomes: Immunology 2 Review antibody mediated and cell mediated immunity by reading appropriate resources and completing a self assessment quiz Define and recognise the variances between antibody mediated and cell mediated immunity Recognise and explain passive and active immunization 6 Antibody-mediated and cell-mediated immunity Consolidation of learning The Cellular Immune Response – YouTube https://www.youtube.com/watch?v=oUpcRfpEh3c ANTIGEN PROCESSING AND PRESENTATION – YouTube https://www.youtube.com/watch?v=Bgd1qxQ0Dh4&feature=emb_logo 7 8 Passive and active immunity Acquired (adaptive) immunity Passive Active immunity immunity Natural passive immunity: Artificial passive immunity: Natural active immunity: Artificial active immunity: e.g mother’s antibodies Transferred therapeutically Antibodies developed in Antibodies developed in through placenta/breast milk e.g. snake antitoxin, response to infection response to a vaccination Immunoglobulin – transplant Transfer of antibody or of sensitised cells from Production of antibodies against a specific an immune person to a non-immune person. agent after exposure to the antigen. -Short duration. Person at risk when immunity -Specific antibodies identified as foreign runs out. -Response is specific to a particular antigen - Used when infection risk is high/own response -Memory: antigen is remembered not developed 9 Immunisation Artificial active immunity: antibodies develop after immunisation/administration of vaccine. How does this happen? Ø Immunological memory Ø A specific immune reaction induced against a weakened/killed microorganism Ø Subsequent infections from same pathogen raises a stronger and faster defensive reaction Ø This reaction may come from antibodies and/or cells. Ø Antibodies attach to specific surface structures on antigen – activates the complement system (see immunology 1) 1 0 Vaccines and the immune response https://www.youtube.com/watch?v=Atrx1P2EkiQ 1 1 References: An introduction to immunology and immunopathology Richard Warrington1*, Wade Watson2 , Harold L Kim3,4, Francesca Romana Antonetti5 McMahon R., Sloan P.
