Research description

Phosphoinositide 3-kinases (PI3Ks) are enzymes that act downstream of tyrosine kinase signalling and generate second messenger signalling molecules that can regulate cell survival, metabolism, growth, proliferation, differentiation and migration. We are investigating the regulation of PI3Ks in lymphocytes using genetic and pharmacological approaches. We also investigate how manipulation of PI3K signalling influences different kinds of immune responses including against cancer. Results from these investigations help provide rationale for the use of PI3K inhibitors in therapeutic settings. Indeed, the PI3Kdelta inhibitor idelalisib is already approved for the treatment of certain B cell malignancies (CLL, SLL, FL) and PI3Kdelta inhibitors are also being trialled as immunotherapeutic agents in solid cancer.
