Having obtained EMBO Long-term Fellowship and Marie Curie Intra-European Fellowship, she then moved to London to carry out her postdoctoral studies in the field of PI3K biology together with Prof Bart Vanhaesebroeck at the Barts Cancer Institute, QMUL. In 2013, she was appointed as a Lecturer to start the “Mucosal Immunity and Signalling” group within the William Harvey Research Institute.ResearchGroup members Post-doctoral Researchers & Fellows: Luiz Ricardo Vasconcellos PhD students: Laura Medrano PI3K signalling role in shaping host-microbiome interactionsThe intestinal mucosa is a large immunologic organ, lined up with trillions of microbes and plays a key role in the development of oral tolerance and host-defence. Our studies are aimed to uncover how phosphatidylinositol lipid signalling by phosphoinositol 3-kinases (PI3Ks) control innate immunity and translate innate immune receptor mediated signals during host-microbial interplay in the gastrointestinal tract to influence systemic immunity to pathogens, tolerance, and responses to immunotherapy. Elucidation of these fundamental mechanisms will help us uncover how conventional protective immune responses differ from pathogenic ones that result in autoinflammation and autoimmune disease. PI3K role in the control of intestinal epithelial cell responses to intestinal injury and infectionThe intestinal epithelium is the fastest self-renewing, complex and large tissue in mammals. Intestinal epithelial cells (IECs) play an essential role in the absorption of nutrients and provides the primary physical and biochemical barrier against pathogens, yet while induce tolerance to food antigens and commensal microbiota. Our group studies the molecular mechanisms how PI3K signalling shapes IEC regenerative response to changes in metabolic cues and microbial products under normal conditions and injury states.
