PI3K activation in neural stem cells drives tumorigenesis which can be ameliorated by targeting the cAMP response element binding protein

Our findings present a novel mouse model for glioma demonstrating that the PI3K pathway is important for initiation of tumorigenesis

Partial trisomy 21 contributes to T-cell malignancies induced by JAK3-activating mutations in murine models

This JAK3A572V knockin model is a relevant new tool for testing the efficacy of JAK inhibitors in JAK3-related hematopoietic malignancies

Regular exercise improves the well-being of parents of children with cancer

Mental health benefits of a pedometer-based exercise intervention for parents of children with cancer were identified.

Immunogenicity and safety of single-dose, 13-valent pneumococcal conjugate vaccine in pediatric and adolescent oncology patients

All children who are receiving therapy for cancer should receive a single dose of PCV13 as soon as possible after diagnosis, regardless of prior PCV exposure.

Contemporary survival endpoints: An international diffuse intrinsic pontine glioma registry study

This study defines PFS and OS, and is the first describe post-progression survival in a large cohort of children with DIPG.

Advancing CNS tumor diagnostics with expanded DNA methylation-based classification

DNA methylation-based classification is now central to contemporary neuro-oncology, as highlighted by the World Health Organization classification of central nervous system tumors. This expansion is a result of newly identified tumor types discovered through our large online repository and global collaborations, underscoring CNS tumor heterogeneity.

Flt3L-mediated tumor cDC1 expansion enhances immunotherapy by priming stem-like CD8+ T cells in lymph nodes

Immune checkpoint blockade (ICB) evokes antitumor immunity through the reinvigoration of T cell responses. T cell differentiation status controls response, with less differentiated cells having an enhanced capacity to proliferate after ICB. Given that conventional type 1 dendritic cells (cDC1) maintain precursor exhausted T cells (TPEX), we hypothesized that expansion of cDC1s with Flt3L could enhance responses to ICB. 

Comparative analysis of malignant pleural effusion and peripheral blood reveals unique T cell signatures associated with survival in mesothelioma patients

The success of cancer immunotherapies has highlighted the importance of monitoring the anti-tumour T cell response. Patients with mesothelioma frequently present with a malignant pleural effusion (MPE) that is commonly drained regularly to alleviate symptoms. As MPE contains tumour cells, T cells and cytokines, it provides a unique opportunity to sample immune events at the tumour site.

Beyond bone: the emerging role of osteoclasts in immune regulation, leukemia development and following myeloablative therapy

Osteoclasts are important regulators of bone remodeling, with an established role in maintaining skeletal homeostasis. The emergence of osteoimmunology has identified osteoclasts as key players in the immune system. In particular, osteoclasts can initiate bi-directional crosstalk mechanisms with hematopoietic stem cells and various immune cells, such as T cells, B cells and NK cells, to influence hematopoiesis and inflammatory response.

Histone methyltransferase PRDM9 promotes survival of drug-tolerant persister cells in glioblastoma

Chemotherapy often kills a large fraction of cancer cells but leaves behind a small population of drug-tolerant persister cells. These persister cells survive drug treatments through reversible, non-genetic mechanisms and cause tumour recurrence upon cessation of therapy. Here, we report a drug tolerance mechanism regulated by the germ-cell-specific H3K4 methyltransferase PRDM9.
