Georgia Perona-Wright

Immune responses can be both protective and pathological. Dr. Georgia Perona-Wright's aim is to understand how the balance between these two outcomes is achieved, focusing on the role of cytokines in the context of infection.

She is particularly interested in the interaction between coincident, opposing cytokines:

> What dictates the appropriate polarisation of an immune response to infection?

> Do these instructions affect cells not specific for the initiating pathogen?

> Can this cytokine cross-talk be manipulated for therapeutic gain?
