Dr Anthony Sadler

Dr Sadler investigates components of our immune system. After completing his early research training in microbial genetics at the University of Canterbury and virology at the University of Otago he travelled to the US where he conducted postdoctoral research into host immune responses to microbial pathogens at the Learner Research Institute. In 2007, he came to Australia where he took up a position as a Senior Research Fellow within Hudson Institute. Dr Sadler investigates innate immune responses that regulate inflammation with the aim of identifying strategies to limit pathologies and treat ensuing disease.

His research currently focuses on three response molecules that together transduce cell signals and induce gene responses that he has shown control inflammation. Dr Sadler investigates a progression of immune pathologies from the initial responses to infection, through the development of chronic inflammatory conditions (colitis), to established chronic autoimmune diseases (type I diabetes and lupus).
