Description The human immune system is a milieu of cells, cytokines, chemokines, growth factors and cell adhesion molecules which form an elaborate molecular communication network through a number of signalling networks and molecules. The relevance of this knowledge for understanding the pathology and specific diseases of the human immune system are emphasised through the subject. This subject also provides an in depth analysis of the molecular mechanisms of cell to cell communication, cell activation, the immunological synapse, transplant rejection (including adoptive transfer experimentation), antigen presentation, B and T cell recruitment and MHC restriction. Medical and diagnostic applications of hybridoma technology, antibody engineering and advances in vaccine development are discussed. The laboratory course will develop technical and interpretative skills in relevant techniques, in particular the ImmunoCAP technology for asthma and allergy diagnosis.

On successful completion of this subject, students should be able to:
- Describe the structures and roles of key molecules in the immune response, including antibodies, complement, B and T cell receptors, MHC molecules and cytokines.
- Explain the events involved in B and T cell receptor gene rearrangements, the generation of antibody diversity and class switching.
- Explain the role of MHC genes in generating histocompatability.
- Discuss current knowledge about the molecular basis of the immune response, including the roles of cytokines and cell signalling pathways for both humoral and cell-mediated responses.
- Analyse the roles of the humoral and cell-mediated responses in dealing with different types of infection and explain the interrelationships between these two arms of the immune system.
- Explain the applications of this knowledge for the production and use of monoclonal antibodies, the engineering of antibodies, and the development of new therapeutics and immunodiagnostic assays.
- Demonstrate an understanding of advances in vaccine development, including protein and DNA vaccines, and the issues which relate to successful vaccine design.
- Present, organise and interpret experimental data in concise written English.
- Explain and apply principles relating to immunological and immunochemical methodologies for the design and conduct of effective diagnostic and research procedures.
- Access and analyse relevant scientific journal papers.
- Present a written critique of an assigned topic.
- Conduct qualitative and quantitative laboratory techniques involving antibodies and understand their applications.
