Whole-Genome Sequencing Shows Strong Real-World Impact in Precision Oncology
Journal: Nature Medicine
Author: van Putten, J., Snaebjornsson, P., Bosch, L.J.W. et al., The Netherlands
In a real-world study of 888 solid cancer patients, whole-genome sequencing (WGS) successfully identified actionable biomarkers in 73% of cases, enabling more personalized treatment decisions with a rapid 6-day turnaround. Patients receiving biomarker-informed therapies experienced significantly improved outcomes, including a 31% increase in overall survival, highlighting WGS as a powerful tool for routine clinical oncology.
Spatially Organized Macrophage Niches Shape Tumor Immunity
Journal: Nature Immunology
Author: Ghosh, S., Li, X., Rawat, K. et al., USA
This study reveals that distinct macrophage subsets occupy specific tumor regions and play opposing roles, with chemokine-expressing tissue-resident macrophages promoting lymphocyte recruitment and tumor control, while others recruit immunosuppressive, tumor-supporting cells. Targeting these spatially defined immune interactions – such as blocking CCR5 to limit suppressive cell migration – can enhance antitumor immunity and improve responses to therapies like neoantigen vaccination.
Engineered Bacteria Boost Immunotherapy via Nitric Oxide Production
Journal: Nature Biotechnology
Author: Xu, S., Zhang, T., Song, Y. et al., China / Singapore
Engineered E. coli capable of sustained nitric oxide production can remodel the tumor microenvironment by normalizing vasculature, reducing immunosuppression, and enhancing immune cell activity. This approach significantly improves the effectiveness of anti–PD-L1 immunotherapy, leading to durable tumor regression and long-lasting antitumor immunity in multiple cancer models.
Immune Interactions Drive Risk and Protection in Congenital Zika Syndrome
Journal: Science Immunology
Author: Abhay P. S. Rathore, Ashley L. St. John
Zika virus infection during pregnancy can lead to congenital Zika syndrome through complex interactions between maternal and fetal immunity, viral factors, and metabolic conditions that influence fetal outcomes. Understanding these immune mechanisms – along with factors like prior flavivirus exposure and genetic variation – provides important insights for developing vaccines and therapies for congenital infections.
