Theory and Techniques in Infection and Immunity

Module code: BS4308

Modern laboratory techniques in molecular and cellular biology are essential tools in the fight against infectious diseases. They have revolutionised our understanding of pathogenic micro-organisms, of the mechanisms whereby they colonise host tissues, of their molecular vulnerabilities which allow novel therapies (including antibiotics) to be developed, and of the host immune responses which serve to protect against infections.

In this module you will learn about the key molecular theory that underpins molecular and cellular biology, and then apply this theory in a series of laboratory practicals which show exactly how these techniques can be applied at the laboratory bench to real biological problems relevant to infectious diseases. We will examine both prokaryotic and eukaryotic cell biology, as well as molecular regulation and infectious disease progression.

This is a vital module for increasing your employment prospects as a biomedical scientist, bridging the gap between theory and practice, and preparing you for the 6 month supervised laboratory research project which takes up the whole of semester 2 of the MSc.
