Intracellular antibody neutralization of adenovirus infection

Despite extracellular adaptive and innate immunity, viral and bacterial pathogens are still able to infect cells. Because of this there must be a way to neutralise pathogens once they are inside the cell. Historically, infected cells have been seen as largely helpless and only able to signal for help. However, there is increasing evidence that cells have their own mechanisms for directly restricting pathogen replication. It is this process of intracellular immunity that my lab is interested in.

Intracellular antibody immmunity

In order to study intracellular immunity, we are combining cellular pathogen infection experiments with structural and biophysical approaches. Using these techniques we are attempting to address how the host targets fast evolving pathogens and the different mechanisms that are employed to neutralise them.
