Ibrutinib and PD-1 Blockade Potentiate Mesothelin-Targeting CAR T-cell Therapy in Preclinical Models of Pancreatic Cancer.
In Clin Cancer Res on 4 February 2026 by Armstrong, A., van der Plancke, G., et al.
PubMed
Pancreatic ductal adenocarcinoma (PDAC) remains refractory to chimeric antigen receptor (CAR) T-cell therapies because of its immunosuppressive microenvironment and a dense extracellular matrix deposited by cancer-associated fibroblasts (CAF), which impair CAR T-cell infiltration. To address these barriers, we previously developed a dual-targeting CAR-TEAM platform in which mesothelin-specific CAR T cells secrete a fibroblast activation protein (FAP)-targeting T-cell engager antibody molecule (TEAM) to simultaneously kill tumor cells and CAF. In this study, we leveraged mesothelin-targeting CAR T cells and tested rational drug combinations and optimal delivery strategies to enhance therapeutic efficacy and guide potential combinations that could be incorporated into a clinical study.

Interleukin-15 (IL-15) is a pleiotropic cytokine recognized as a promising therapeutic agent in cancer immunotherapy. IL-15 superagonists have shown efficacy across various cancers, yet their effects in lung cancer immunotherapy remain underexplored.

Early NK-cell and T-cell dysfunction marks progression to severe dengue in patients with obesity and healthy weight.
In Nat Commun on 1 July 2025 by Gregorova, M., Santopaolo, M., et al.

Dengue is a mosquito-borne virus infection affecting half of the world's population for which therapies are lacking. The role of T and NK-cells in protection/immunopathogenesis remains unclear for dengue. We performed a longitudinal phenotypic, functional and transcriptional analyses of T and NK-cells in 124 dengue patients using flow cytometry and single-cell RNA-sequencing. We show that T/NK-cell signatures early in infection discriminate patients who develop severe dengue (SD) from those who do not. These signatures are exacerbated in patients with overweight/obesity compared to healthy weight patients, supporting their increased susceptibility to SD. In SD, CD4+/CD8+ T-cells and NK-cells display increased co-inhibitory receptor expression and decreased cytotoxic potential compared to non-SD. Using transcriptional and proteomics approaches we show decreased type-I Interferon responses in SD, suggesting defective innate immunity may underlie NK/T-cell dysfunction. We propose that dysfunctional T and NK-cell signatures underpin dengue pathogenesis and may represent novel targets for immunomodulatory therapy in dengue.
