Cellular Basis of Immunity

Module description

In this module you will explore the science of immunology, and how the major cellular and humoral (soluble) components of the innate and adaptive immune systems work together to deliver immunity to infectious diseases. You will develop an understanding of how monoclonal antibodies are generated and engineered in vitro for use in the diagnosis and treatment of human diseases, and the various ways antibodies are used as research tools in the Life Sciences. Lecture content is supported by animations and videos that illustrate key concepts of immunity including cellular interactions during the inflammatory response, and the role of cytokines and chemokines as chemical messengers.

You cannot take this module if you have already taken CSC2008 Immunopathology.

Module aims - intentions of the module

This module aims to introduce you to the science of immunology. Key components of the immune system are explored in the context of infectious diseases (viral, bacterial, fungal and parasitic infections) and allergy, and current research topics used to illustrate how antibodies are engineered and used in the detection and treatment of diseases in contemporary medicine and environmental sciences. Much of the content is research-led owing to the convenor’s research expertise in hybridoma technology, monoclonal antibody production and the generation, protection and exploitation of intellectual property in the arena of medical diagnostics.

Intended Learning Outcomes (ILOs)

ILO: Module-specific skills

On successfully completing the module you will be able to...

• 1. Critically evaluate our understanding of the innate and adaptive immune systems, antibody structure and function, and the immune response to infectious diseases
• 2. Describe in detail and analyse the defining characteristics of mouse hybridoma technology and other technologies e.g. phage display for monoclonal antibody generation and use in diagnostics and therapeutics
• 3. Explain the use of antibodies in various aspects of medicine and environmental sciences

ILO: Discipline-specific skills

On successfully completing the module you will be able to...

• 4. Evaluate in detail approaches to our understanding of immunology with reference to primary literature, reviews and research articles
• 5. Analyse in detail essential facts and theory in a sub-discipline of the biosciences
• 6. Analyse and evaluate independently a range of research-informed literature and synthesise research-informed examples from the literature into written work
• 7. With limited guidance, deploy established techniques of analysis and enquiry within the biosciences

ILO: Personal and key skills

On successfully completing the module you will be able to...

• 8. Communicate effectively arguments, evidence and conclusions using written means in a manner appropriate to the intended audience
• 9. Devise and sustain, with little guidance, a logical and reasoned argument with sound, convincing conclusions

Formative assessment

Summative assessment (% of credit)

Details of summative assessment

Details of re-assessment (where required by referral or deferral)

Re-assessment notes

Deferral – if you miss an assessment for certificated reasons that are approved by the Mitigation Committee, you will normally be either deferred in the assessment or an extension may be granted. If deferred, the format and timing of the re-assessment for each of the summative assessments is detailed in the table above ('Details of re-assessment'). The mark given for a deferred assessment will not be capped and will be treated as it would be if it were your first attempt at the assessment.

Referral - if you have failed the module (i.e. a final overall module mark of less than 40%) and the module cannot be condoned, you will be required to complete a re-assessment for each of the failed components on the module. The format and timing of the re-assessment for each of the summative assessments is detailed in the table above ('Details of re-assessment'). If you pass the module following re-assessment, your module mark will be capped at 40%.
