Fungal Immunology

As a new group within the Division of Immunology, this group focuses on fungal infections associated with immune deficiency. Fungal infections are often an overlooked clinical and public health issue. Certain fungal species have immediate devastating effects on health, while other infections are chronic with little or no potential treatment. With the increase of diseases rendering patients immunocompromised such as HIV/AIDS, the incidence of opportunistic fungal infection is synonymously increasing with detrimental effects. One such fungus, Pneumocystis jirovecii causes pneumonia in HIV/AIDS patients leading to mortality unless treated aggressively. Although the use of highly active antiretroviral therapy has decreased the incidence of Pneumocystis Pneumonia the morbidity and mortality remain high. The focus of the research group is to identify innate immune signalling mechanisms in response to Pneumocystis in the immunocompromised host. Furthermore, considering the presence of other pathogens in HIV infected individuals, with particular emphasis on Mycobacterium tuberculosis (MTB) and helminths, the group also focuses on identifying an impact of co-infection on the prevalence of Pneumocystis Pneumonia.

Projects include:

  • Innate immune signalling mechanisms in Pneumocystis Pneumonia 
  • The role of innate immune receptors in response to clinical isolates of MTB
