Rational combination platform trial design for children and young adults with Diffuse Midline Glioma: a report from PNOC

Sebastian Martin Waszak

Diffuse midline glioma (DMG) is a devastating pediatric brain tumor unresponsive to hundreds of clinical trials. Approximately 80% of DMGs harbor H3K27M oncohistones, which reprogram the epigenome to increase the metabolic profile of the tumor cells. We ha ...

KRAB zinc finger proteins link heterochromatin maintenance to replicative stress and inflammation in diffuse large B-cell lymphoma

Filipe Amândio Brandão Sanches Vong Martins

Genomic instability enhances cancer progression by favoring clonal diversity, yet uncontrolled replicative stress can lead to mitotic catastrophe and inflammatory responses promoting immune rejection. KRAB-containing zinc finger proteins (KZFPs) are epigen ...

Microfluidic T Cell Selection by Cellular Avidity

Armand Kurum, Li Tang, Alexandre Harari

No T cell receptor (TCR) T cell therapies have obtained clinical approval. The lack of strategies capable of selecting and recovering potent T cell candidates may be a contributor to this. Existing protocols for selecting TCR T cell clones for cell therapi ...

Cell-autonomous inflammation of BRCA1-deficient ovarian cancers drives both tumor-intrinsic immunoreactivity and immune resistance via STING

Christian Iseli, Julien Dorier, Mauro Delorenzi, Alizée Jéléna Grimm, Marco Mina, George Coukos, Alexandre Harari, Giovanni Ciriello

In this study, we investigate mechanisms leading to inflammation and immunoreactivity in ovarian tumors with homologous recombination deficiency (HRD). BRCA1 loss is found to lead to transcriptional reprogramming in tumor cells and cell-intrinsic inflammat ...
