Cancer and Innate Immunity

Research Group Heads

Scientists in the Cancer and Innate Immunity laboratory are interested in the role of the innate immune system in the regulation of cell growth and differentiation, as well as
in establishing acquired immune responses. We are investigating the innate immune response to RNAs, in both viral infections and other disease processes, including inflammation, autoimmune disease and tumour immunity. We are also looking at the roles of transcription factors such as PLZF and ATF3 as regulators of molecular signalling pathways in the innate immune system, focusing on both antiviral responses and immune mechanisms in cancer. In addition, we are focusing on the effect of pro-inflammatory cell signalling on cancer progression and are developing inhibitory therapeutics to suppress tumour growth.

Recent Achievements

– We identified the transcription factor PLZF as a key regulator of the antiviral response.
– We discovered that regulation of the actin-modifying protein gelsolin limits viral entry into cells.
– We found that the transcription factor ATF3 suppresses metastasis in bladder cancer.
– We showed that the protein kinase PKR represses inflammasome activity to control inflammation.
– We discovered that PLZF curbs inflammatory cell signalling.
