FIRST TALK:   Self versus foreign – how does the immune system learn?

The immune system is the general line of defence for the body against bacterial infections and viruses.

The immune system is made up of a variety of different tissues such as the spleen or lymph nodes. Several cell types produce different proteins such as antibodies which are contributing to immune responses.  This talk will focus on the thymus, the organ responsible for ‘educating’ certain types of immune cells, known as T cells.  Through this ‘education process’, a response of immune cells against the body’s own tissues (termed autoimmunity) is prevented.  In this talk I will discuss the discovery of autoimmunity and the remaining mysteries surrounding the processes which the body has developed to prevent it from occurring.

SECOND TALK: Colloidal Polymers

Understanding the formation, ageing and failure of particle gels is both of fundamental interest and industrial importance. Numerous commercial products contain active ingredients, which contain colloidal polymers. Polymers or clays are routinely added to such systems as thickening agents. The addition of these often results in the formation of particle or colloidal gels, the lifetime and behaviour of which can be difficult to predict.
