Immunobiology is the study of defence mechanisms that protect living organisms against life-threatening infections. In this unit of study you will explore the essential features of the host immune responses and how it evolved from unicellular organisms to complex multi-cellular organisms. Studies in animal and microbial immunobiology are leading to breakthroughs in veterinary and clinical medicine, including combatting infectious diseases, maximising transplant success, treating allergies, autoimmune diseases and cancer, as well as development of new vaccines to prevent disease. Understanding the immunobiology of plants also enables us to protect crops from disease which enhances our food security. In this unit of study you will be provided with a detailed overview of immunobiology as a basic research science. We will explore in detail the nature of the immune cells and molecules that recognise danger and how the immune system of animals and plants respond at the cellular and molecular level. Advanced practical and tutorial sessions are designed to illustrate particular concepts introduced in other face-to-face activities. Further self-directed learning activities, including online learning activities, will facilitate integration of fundamental information and help you apply this knowledge to the ways in which the host organism defends against disease. This advanced version of Immunobiology has the same overall concepts as the mainstream unit but material is discussed in a manner that offers a greater level of challenge and academic rigour. Students enrolled in the advanced stream will participate in alternative components which may for example include guest lectures from experts. The nature of these components may vary from year to year.
