Recent advances in the field of biological sciences have revolutionised the way we understand and treat disease. Stem cell and novel cell-based therapies and personalised medicine are increasingly in the headlines and Biological Scientists are leading the way in developing these powerful new therapeutic options.Modern medicine requires an understanding of the key interactions of molecules and cells both internally - within the cell and the body - and externally from the environment. This can include how a cell responds to a specific pathogen, or how a drug targets a specific pathogen or cellular protein. Equally, external stimuli, such as chemicals, toxic waste or carcinogens, can also have an effect on how cells grow and divide, modifying their function with devastating consequences for health.The Biological Sciences course at Glasgow Caledonian University (GCU) has a strong focus on human disease and aims to help you understand these events, and demonstrate how therapies that may correct or prevent the diseased state are developed.
