Dendritic cell mobilization

Immunotherapies, in particular those targeting T lymphocytes (LT), have shown convincing results in many tumors but very little in breast cancer despite the presence of an important immune infiltrate. It is therefore necessary to develop new targets/strategies to direct the immune system towards an effective anti-tumor response in this pathology.
LT activation is mediated by antigen-presenting cells, in particular dendritic cells (DCs). Conventional type I dendritic cells (cDC1) seem to be very interesting. Indeed, our group and others have shown the functional superiority of cDC1 to present tumor Ag to CD8+ T cells. Moreover, we have shown for the first time the infiltration of primary breast tumors by cDC1 and observed that there are correlated with good patient prognosis in many types of cancer. In human breast tumor, cDC1 specifically produced a particular interferon (IFN) named type III interferon (IFN-III) which is able to potentialize an antitumor immune response and which is also correlated to a good patient prognosis.
However, the precise role of cDC1 and other DCs in the establishment of an anti-tumor immune response or in response to immunotherapies is not well known in humans. Thus, in order to answer the numerous questions that arise, my group is developing three complementary research axes on:
- The role of DCs and IFN-III in the immune surveillance of the early phases of cancer;
- The identification of IFN-III effects on the tumor microenvironment and in the blood;
- The clinical impact of different DC populations on the response to immunotherapies and the role of each of those different DC populations in the tumor microenvironment.
