Macrophage modulation during viral infection and neuroinflammation

Tissue macrophages, including the microglia in the brain, act as critical sentinels to defend us against infection. Consequently, pathogens such as HIV have developed ways of circumventing the defensive functions of macrophages in order to establish chronic infection. Moreover, their persistence in...

Host-pathogen interactions

An understanding of the way in which an invading pathogen interacts with its host at a molecular level is an essential aid to understanding the nature and extent of disease caused. My group aims to use a variety of techniques to probe the interactions that characterise different disease processes. Central to this approach is the use of X-ray...

Advancing understanding of HIV pathogenesis and vaccine design

Our current research spans the fields of HIV-1 dissemination, HIV-1 antibody-based vaccine design, and the molecular basis of allergy. We use a multi-disciplinary approach, which includes immunology, virology, chemistry, and cell biology together with cutting-edge imaging techniques to address fundamental...

Bacterial pathogenesis: molecular mechanisms to prevention

Human bacterial pathogens are a specialized subset of array microbes we encounter as part of our flora. The group seeks to understand the basis of how pathogens colonise specific niches in the body, evade elimination by the immune system, and cause disease. We study Neisseria spp., which are leading...

Anton van der Merwe

Recognition of abnormal cells by leukocyte receptors

The group studies the mechanisms by which leukocytes, such as T cells, use cell surface receptors to recognise infected or otherwise abnormal cells. The T cell receptor (TCR) plays a major role in this process by probing the surfaces of cells for the presence of 'foreign' peptides presented on MHC molecules in a...

Harnessing mechanisms of immunological tolerance for therapeutic purposes.

Unwanted immune responses have a major impact on human health and wealth. Their management has required long-term immunosuppressive drugs which penalise the whole immune system. The big challenge has been to understand how the individual is naturally tolerant to self, and to exploit this...
