Course and current status

PI Inserm U1111

Biography: Principle Investigator at the International Center for Infectiology Research (CIRI), Lyon, France, for the last ten years, I have been working in the field of innate immunity. My career path started at Kings College then at St Bart's and Royal London Medical School where I was awarded her PhD in Immunology. My post doctoral training was based at Schering Plough under the direction of Giorgio Trinchieri working in the field of Toll Like Receptors. I worked on HPV, EBV and HBV immune escape from innate receptor sensing. This led to forming a theme within Inserm in which I continue to understand how chronic diseases can prevent innate immune responses.

Scientific summary

Chronic diseases and Immunity

Research

Oncoviruses and cancer cells have the capacity to escape immune surveillance and promote cellular transformation in order to persist and progress in humans. Innate immune responses play a crucial role in the control of viral replication and are required for a timely orchestration of specific adaptive responses against the infection. The innate immune system can sense pathogen components via the Toll Like Receptor (TLR) family and cytosolic receptors. We observed that the human papillomavirus type 16 (HPV16) (associated with cervical cancer), a virus that infects the basal epithelium, can effectively deregulate the expression and function of Toll Like Receptor 9 (TLR9). We have also shown that TLR9 is deregulated by hepatitis B virus as well as another double-stranded DNA sensor,  AIM2.  Another ambitious goal will be to determine whether TLR9 has a role in regulating the cell cycle in cancer, in particular, to determine the mechanisms that induce events leading to cell death. This highlights a new function of Toll Like Receptors and underscores why TLR9 is targeted in chronic diseases. We have also shown that NK cells from HBV infected patients display an exhaustive phenotype similary to those described in T cells.  More recently, by performing CRISPR/Cas9 screens we have identified new genes that render tumour cells resistant to primary NK cell killing.

Clinic

All studies are conducted in humans and require intensive use of primary human cell cultures in P2/P3 facilities, and tight collaboration with labs and hospitals based nationally and internationally. Most importantly, all our research is corroborated in the clinic with inclusions from patients. Our studies in TLR9-B and NK cell deregulation by HBV have been done in with the CHU hospital in Limoges. Here we set up a study to recruit blood, serum and PAX/RNA samples from patients with Chronic Hepatitis B infection. In addition, in collaboration with the IARC, Lyon, we examined whether certain polymorphisms in innate receptors will influence the risk of cervical cancer using DNA samples from women in different regions of the world. The TLR9 cell cycle project is being performed in collaboration with the CRCL and Kings College in London.
