Bill Horsnell’s research team applies a range of mouse infectious disease models to their various research projects. Their main focus is on how helminth infections influence our immune system. Current projects focus on:
Under-explored influences of helminth on host immunity. Currently we are exploring roles for neurotransmitters in regulating immunity, studying how helminths regulate the innate immune molecules surfactant protein A and D, and how maternal infection influences offspring immunity.
Pre-clinical and clinical studies addressing how exposure to helminths alters host ability to respond to unrelated diseases including colon cancer, mTB, salmonella, RSV infection, and allergy.
