Professor Gordon Brown’s primary research area is innate immunity, with particular emphasis on C-type lectin receptors and their role in antimicrobial immunity and homeostasis. Much of his earlier work has revolved around studying the functions of the C-type lectin Dectin-1, a receptor for beta-glucan carbohydrates that plays a key role in anti-fungal immunity. Dectin-1, and subsequently other C-type lectins, were found to be able to mediate numerous cellular responses, to trigger intracellular signalling through novel pathways, and to modulate and directly induce innate and adaptive immune responses.

His current research continues to explore the roles and functions of C-type lectins as well as their involvement in antifungal immunity. He is a member of the Aberdeen Fungal Group (AFG). He is also an adjunct member of the Institute of Infectious Diseases and Molecular Medicine ( at the University of Cape Town), where he maintains a small research group focussing on innate anti-mycobacterial immunity.

To recognise infection, the immune system utilizes sensors on immune cells called “pattern recognition receptors” which detect invading pathogens. These sensors then trigger a number of responses which are aimed at providing protection against the infection. Our group is focussed on understanding a particular group of these pathogen sensors, called the C-type lectins (CLRs), which stemmed from our discovery of the first receptor in this class, Dectin-1.

We have shown that CLRs are able to induce essential immune responses, and have determined the mechanisms that they utilize to trigger these effects. Importantly, we have shown that CLRs play a central role in protective immune responses during fungal infections and identified genetic variants of Dectin-1 in humans, which can confer susceptibility to disease.

We have also determined that defects in recognition by pathogen sensors can result in an untreatable fungal infection of the skin, called chromoblastomycosis; work which has led directly to the testing of a novel treatment in humans.

Our current research is aimed at gaining a more detailed understanding the role of CLRs in immunity during fungal infection, and exploring the roles and functions of new CLRs that we have recently identified.
