Skin tumor immunity: Site does matter for antigen presentation by DCs

Timely mobilization of tumor antigen-bearing dendritic cells (DCs) from the periphery to the lymph nodes is critical for effective antitumor T-cell immunity

Research

Tumour draining lymph node-generated CD8 T cells play a role in controlling lung metastases after a primary tumour is removed but not when adjuvant immunotherapy is used

Surgical resection of cancer remains the frontline therapy for millions of patients annually, but post-operative recurrence is common, with a relapse rate of around 45% for non-small cell lung cancer. The tumour draining lymph nodes (dLN) are resected at the time of surgery for staging purposes, and this cannot be a null event for patient survival and future response to immune checkpoint blockade treatment. This project investigates cancer surgery, lymphadenectomy, onset of metastatic disease, and response to immunotherapy in a novel model that closely reflects the clinical setting. In a murine metastatic lung cancer model, primary subcutaneous tumours were resected with associated dLNs remaining intact, completely resected or partially resected.

Invasive fungal disease in children with solid tumors: An Australian multicenter 10-year review

Invasive fungal disease (IFD) occurs less frequently during treatment for solid compared to hematological malignancies in children, and risk groups are poorly defined. Retrospective national multicenter cohort data (2004-2013) were analyzed to document prevalence, clinical characteristics, and microbiology of IFD.

Local immunotherapy for sarcoma

We are developing a gel that can be left behind in the wound bed after sarcoma surgery.

Dietary Vitamin D Increases Percentages and Function of Regulatory T Cells in the Skin-Draining Lymph Nodes and Suppresses Dermal Inflammation

Dietary vitamin D3 increased the suppressive activity of regulatory T cells in the skin-draining lymph nodes, which are poised to suppress dermal inflammation

Inhibition of Autophagy Promotes the Elimination of Liver Cancer Stem Cells by CD133 Aptamer-Targeted Delivery of Doxorubicin

Doxorubicin is the most frequently used chemotherapeutic agent for the treatment of hepatocellular carcinoma. However, one major obstacle to the effective management of liver cancer is the drug resistance derived from the cancer stem cells.

Genes involved in platelet aggregation and activation are downregulated during acute anaphylaxis in humans

Mechanisms underlying the anaphylactic reaction in humans are not fully understood. Here, we aimed at improving our understanding of anaphylaxis by investigating gene expression changes.

Non-severe burn injury increases cancer incidence in mice and has long-term impacts on the activation and function of T cells

Recent evidence suggests that burn patients are at increased risk of hospital admission for infection, mental health conditions, cardiovascular disease and cancer for many years after discharge for the burn injury itself.

Research

Rewiring endogenous genes in CAR T cells for tumour-restricted payload delivery

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.
