New therapeutic perspectives for rhabdoid tumors
Cancer Cell journal logo

Rhabdoid tumors are one of the tumors presenting the fewest mutations among all human cancers; their ability to induce an immune response was presumed low until this study. 

An integrated analysis of the immune infiltrate using immunohistochemistry , RNAseq and methylation profiles of a large series of rhabdoid tumors showed that a large proportion of tumors are abundantly infiltrated by T cells and myeloid cells. Further, scRNAseq (single cell RNA seq) sequencing associated with the sequencing of the gene encoding the T cell receptor revealed clonal expansion of these T cells unexpectedly suggesting the presence of a specific immune response of the tumor

Checkpoint blockade therapy in an experimental model induced the regression of established tumors and durable immune responses paving the way for new therapeutic approaches for children. 

Le blocage des points de contrôle immunitaire effectué sur un modèle murin induit une régression de la tumeur et l’apparition d’une mémoire immune in vivo ouvrant la voie à de nouvelles approches thérapeutiques pour les enfants.
