Successful pancreatic ductal adenocarcinoma (PDAC) immunotherapy requires therapeutic combinations that induce quality T cells. Tumor microenvironment (TME) analysis following therapeutic interventions can identify response mechanisms, informing design of effective combinations. We provide a reference single-cell dataset from tumor-infiltrating leukocytes (TILs) from a human neoadjuvant clinical trial comparing the granulocyte-macrophage colony-stimulating factor (GM-CSF)-secreting allogeneic PDAC vaccine GVAX alone, in combination with anti-PD1 or with both anti-PD1 and CD137 agonist.

Here we show that in hepatocellular carcinoma treated with neoadjuvant immunotherapy, high intratumoral TLS density at the time of surgery is associated with pathologic response and improved relapse-free survival. In areas of tumor regression, we identify a noncanonical involuted morphology of TLS marked by dispersion of the B cell follicle, persistence of a T cell zone enriched for T cell-mature dendritic cell interactions and increased expression of T cell memory markers.

- Pancreatic adenocarcinoma (PDAC) is a challenging cancer to treat with immunotherapies, but certain intratumoral structures called tertiary lymphoid structures (TLS) have been linked to better patient survival outcomes.
- A comprehensive study analyzed 26 PDAC tumors using advanced techniques like machine learning and spatial transcriptomics to better understand the role of TLS within tumors.
- The findings revealed specific gene expression patterns in TLS that correlate with improved survival, highlighting the importance of TLS maturation and its interactions with immune cells and the tumor environment.
Objectives: Hypothermic lung preservation at 10 °C has been recently shown to enhance quality of healthy donor lungs during ischemia. This study aims to show generalizability of the 10 °C lung preservation using an endotoxin-induced lung injury with specific focus on the benefits of post-transplant lung function and mitochondrial preservation.
Methods: Lipopolysaccharide (3 mg/kg) was injected intratracheally in rats to induce lung injury.
