Etude du rôle de STING dans la biologie des lymphocytes T CD4 : application en immunothérapie anticancéreuse
Recognition of danger signals by intracellular or extracellular receptors expressed by innate immune cells is crucial for the establishment of an effective adaptive immune response. STING (Stimulator of Interferon Genes) is a protein located in the endoplasmic reticulum discovered in 2008 as being essential for the detection of cytosolic DNAs and the establishment of antiviral immune response mediated by type I interferons (IFNs). The STING protein also plays a key role in spontaneous anti-tumor immune responses and the administration of STING ligands in tumor-bearing mice favors tumor growth control. These observations have been verified in clinical trials in patients with melanoma, illust…
Rationale for stimulator of interferon genes-targeted cancer immunotherapy
International audience; The efficacy of checkpoint inhibitor therapy illustrates that cancer immunotherapy, which aims to foster the host immune response against cancer to achieve durable anticancer responses, can be successfully implemented in a routine clinical practice. However, a substantial proportion of patients does not benefit from this treatment, underscoring the need to identify alternative strategies to defeat cancer. Despite the demonstration in the 1990's that the detection of danger signals, including the nucleic acids DNA and RNA, by dendritic cells (DCs) in a cancer setting is essential for eliciting host defence, the molecular sensors responsible for recognising these dange…
Harnessing TH9 cells in cancer immunotherapy
CD4 T cell effector subsets not only profoundly affect cancer progression, but recent evidence also underscores their critical contribution to the anticancer efficacy of immune checkpoint inhibitors. In 2012, the two seminal studies suggested the superior antimelanoma activity of TH9 cells over other T cell subsets upon adoptive T cell transfer. While these findings provided great impetus to investigate further the unique functions of TH9 cells and explore their relevance in cancer immunotherapy, the following questions still remain outstanding: are TH9 cell anticancer functions restricted to melanoma? What are the factors favouring TH9 cell effector functions? What is the contribution of T…
