How we are engineering bacteria to eat cancer
medicalxpress - Modern medicine has made significant advances in cancer treatments over the decades. But all cancer therapies still face one critical challenge: how to target cancers without damaging healthy cells.
AI Summary: Researchers engineered bacteria that selectively attack and consume tumor tissue in preclinical models, demonstrating promising tumor control and a novel mechanism to deliver anti‑cancer effects. Significant questions remain about safety, immune responses and delivery in humans, so while the “bacteria that eat cancer” headline is delightful, translation to patients will require cautious, rigorous steps.
Researchers identify immune cell that builds cancer-fighting hubs inside tumors
medicalxpress - Researchers at the Icahn School of Medicine at Mount Sinai have identified the immune cell that acts as the architect and coordinator of powerful immune hubs that form inside tumors and plays a key role in antitumor immunity. This discovery could lead to …
AI Summary: Researchers discovered a subset of dendritic cells that orchestrate formation and maintenance of tertiary lymphoid structures—local immune “hubs”—inside tumours. These niches concentrate and sustain anti-tumour T cells, explaining how some cancers spontaneously marshal immune responses and opening avenues to boost immunotherapy by enhancing or mimicking this dendritic cell-driven architecture.
