<dcterms:abstract xml:lang="fr">Les carcinomes épidermoïdes de la tête et du cou se développent dans la cavité buccale, le pharynx et le larynx et ont un faible taux de survie à 5 ans d'environ 40% en raison de la résistance des cellules cancéreuses aux thérapies utilisées. L'utilisation d'une thérapie ciblée, le cetuximab, n'a permis qu'un gain modeste en termes de survie des patients. Une nouvelle alternative thérapeutique, appelée immunothérapies, vise à lever le frein que les cellules cancéreuses exercent sur les cellules immunitaires. Dans les essais cliniques, les immunothérapies ont montré une grande efficacité, mais chez peu de patients (environ 20%). L'activation de la mort cellulaire spécifique, appelée mort cellulaire immunogène (MCI), active le système immunitaire et pourrait augmenter la proportion de patients chez qui les immunothérapies sont efficaces. On pense que le cetuximab a la capacité de déclencher la MCI dans certains cancers, et donc d'activer le système immunitaire. Au cours de mon travail de thèse, j'ai pu démontrer que le cetuximab seul ou en combinaison induisait l'émission de signaux de danger représentant la première étape de la MCI. J'ai également validé in-vivo l'induction de la MCI par le cetuximab. Au cours de ma thèse, j'ai démontré que le cetuximab peut moduler l'immunogénicité des cellules cancéreuses en impactant l'expression des points de contrôle immunitaires et en induisant la MCI.</dcterms:abstract>
<dcterms:abstract xml:lang="en">Head and neck squamous cells carcinoma develop in the oral cavity, pharynx and larynx and have a low 5-year survival rate of approximately 40% due to the resistance of cancer cells to the therapies used. The use of a targeted therapy, cetuximab, has resulted in only a modest gain in patient survival. A new therapeutic alternative, called immunotherapies, aims to remove the brake that cancer cells exert on immune cells. In clinical trials, immunotherapies have shown great efficacy, but in few patients (about 20%). Activation of specific cell death, called immunogenic cell death (ICD), activates the immune system and may increase the proportion of patients in whom immunotherapies are effective. Cetuximab is thought to have the ability to trigger ICD in certain cancers, and thus activate the immune system. During my thesis work, I was able to demonstrate that cetuximab alone or in combination induced the emission of danger signals representing the first step of ICD. I also validated in-vivo the induction of ICD by cetuximab. During my thesis, I demonstrated that cetuximab can modulate the immunogenicity of cancer cells by impacting the expression of immune checkpoints and inducing ICD.</dcterms:abstract>
