Despite advances in immunotherapy, metastatic melanoma remains a considerable therapeutic challenge due to the complexity of the tumor microenvironment. Intratumoral type I interferon (IFN-I) has long been associated with improved clinical outcomes. However, several IFN-I subtypes can also paradoxically promote tumor growth in some contexts.

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.
The efficacy of chimeric antigen receptor (CAR) T cell therapy in solid tumours is limited by immunosuppression and antigen heterogeneity. To overcome these barriers, 'armoured' CAR T cells, which secrete proinflammatory cytokines, have been developed. However, their clinical application has been limited because of toxicity related to peripheral expression of the armouring transgene.

A vaccine against influenza is available seasonally but is not 100% effective. A predictor of successful seroconversion in adults is an increase in activated circulating T follicular helper (cTfh) cells after vaccination. However, the impact of repeated annual vaccinations on long-term protection and seasonal vaccine efficacy remains unclear.
Despite significant advances, outcomes for children with Down syndrome (DS, trisomy 21) who develop acute lymphoblastic leukemia remain poor. Reports of large DS-ALL cohorts have shown that children with DS have inferior event-free survival and overall survival compared to children without DS.
Children with Down syndrome (DS, trisomy 21) are at a significantly higher risk of developing acute leukemia compared to the overall population. Many studies investigating the link between trisomy 21 and leukemia initiation and progression have been conducted over the last two decades.
Components of the bone marrow microenvironment (BMM) have been shown to mediate the way in which leukemia develops, progresses and responds to treatment. Increasing evidence shows that leukemic cells hijack the BMM, altering its functioning and establishing leukemia-supportive interactions with stromal and immune cells.
Acute erythroleukemia (AEL or acute myeloid leukemia [AML]-M6) is a rare but aggressive hematologic malignancy. Previous studies showed that AEL leukemic cells often carry complex karyotypes and mutations in known AML-associated oncogenes.
