Acute lymphoblastic leukemia expressing the gamma delta T-cell receptor (γδ T-ALL) is a poorly understood disease. We studied 200 children with γδ T-ALL from 13 clinical study groups to understand the clinical and genetic features of this disease. We found age and genetic drivers were significantly associated with outcome.
Gliomas account for nearly 30% of all primary central nervous system (CNS) tumors in children and adolescents and young adults (AYA), contributing to significant morbidity and mortality. The updated molecular classification of gliomas defines molecularly diverse subtypes with a spectrum of tumors associated with age-distinct incidence.
Each year, approximately 1000 children in Australia and New Zealand, aged 0–14 years, are diagnosed with cancer. Despite paediatric cancer accounting for less than 1% of all cancer cases, the impact on their families and communities is profound and disproportionate.
Leukaemia, also spelled leukemia, is a cancer that develops in the bone marrow and results in abnormal white blood cells. It is the most common cancer in children, accounting for almost a third of all childhood & teen cancers.
CD8+ T cells are an important weapon in the therapeutic armamentarium against cancer. While CD8+CD103+ T cells with a tissue-resident memory T (TRM) cell phenotype are associated with favorable prognoses, the tumor microenvironment also contains dysfunctional exhausted T (TEX) cells that exhibit a variety of TRM-like features.
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.
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.
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.
Peroxisome proliferator-activated receptor γ (PPARγ) is a prominent ligand-inducible transcription factor involved in adipocyte differentiation, glucose homeostasis, insulin sensitivity, inflammation, and cell proliferation, making it a therapeutic target for diabetes, metabolic syndrome, autoimmune diseases, and cancer.
