3D Imaging Reveals How Killer T Cells Attack Cancer Inside Tumors

Researchers used cryo-expansion microscopy to preserve near-native cell structure and visualize cytotoxic T lymphocytes at the immune synapse in 3D, revealing a dome-shaped contact interface and variations in cytotoxic granules. Extending the technique to human tumor tissues, the team could observe T cells infiltrating tumors and deploying their killing machinery at nanometer-scale resolution, offering insights that could guide improvements in immuno-oncology therapies.

Thymus: The aging immune regulator linked to longevity and cancer therapy

Scientists are reframing the thymus—a two-lobed gland behind the breastbone—as a central regulator of aging and immune health, with healthier thymuses linked to longer lifespans, lower cancer and heart-disease risk, and better responses to cancer immunotherapy; researchers are pursuing thymus rejuvenation and engineered thymic tissue to boost vaccines and transplant tolerance.

Lilly to Acquire Kelonia for Up to $7B to Advance In Vivo CAR-T Therapy

Eli Lilly agreed to acquire Kelonia Therapeutics for up to $7 billion, with $3.25 billion upfront and the rest tied to milestones, in a deal expected to close in the second half of 2026. Kelonia’s in vivo CAR-T technology aims to reprogram patients’ T-cells inside the body to attack cancer, potentially offering a one-time IV therapy compared with traditional ex vivo CAR-T. Lilly plans to apply the tech beyond multiple myeloma to other blood cancers and possibly solid tumors, as part of a broader push to diversify beyond obesity and diabetes drugs amid ongoing biotech dealmaking and competition from J&J and Gilead-backed therapies.

Pill-Based Donor Microbes Show Early Promise in Boosting Cancer Immunotherapy

Two small Nature Medicine trials suggest oral fecal microbiota transplantation (FMT) pills may boost immunotherapy in advanced cancers: in metastatic kidney cancer, FMT reduced immunotherapy side effects and produced about a 50% response; in advanced lung cancer or melanoma, combining FMT with immunotherapy yielded response rates around 75–80%, higher than typical 39–45% rates. While promising, results are early and require larger trials.

Statins May Boost Immunotherapy by Blocking Cancer PD-L1 Cargo

Researchers found that cancer cells load the immune-inhibiting protein PD-L1 into tiny extracellular vesicles via the protein UBL3, helping tumors suppress immune responses. Statins block this UBL3-driven modification, reducing PD-L1 cargo and potentially improving responses to immune checkpoint inhibitors, with supporting evidence from non-small cell lung cancer patients showing fewer PD-L1–containing vesicles in those taking statins.

KLHL6 tunes T cell fate to boost cancer immunotherapy

A Nature study identifies the E3 ubiquitin ligase KLHL6 as a dual regulator of CD8+ T cell exhaustion and mitochondrial fitness. KLHL6 promotes TOX poly-ubiquitination and degradation, delaying terminal exhaustion, while also restraining excessive mitochondrial fission via the PGAM5–Drp1 axis to maintain T cell metabolism. TCR stimulation downregulates KLHL6, but enforced KLHL6 expression in adoptively transferred T cells enhances anti-tumor and anti-viral responses, highlighting KLHL6 as a clinically actionable target to improve cancer immunotherapy by tuning proteostasis.

Vitamin A's Role in Tumor Immune Evasion and New Cancer Treatment Avenues

Scientists have discovered that a vitamin A metabolite, retinoic acid, can suppress the immune system's ability to fight cancer by promoting immune tolerance. They developed inhibitors that block this pathway, restoring immune responses and improving cancer vaccine efficacy, paving the way for new immunotherapy treatments.

mRNA COVID-19 vaccines show promise in enhancing cancer treatment and survival

A study finds that COVID-19 mRNA vaccines, like Pfizer and Moderna, can boost the immune system to recognize and kill cancer cells, especially when combined with immunotherapy, potentially extending benefits to more cancer patients. The vaccines act as an immune alarm, helping to turn 'cold' tumors 'hot,' and are being tested in clinical trials for lung cancer.

Mitochondria and lysosomes reprogram immune cells to reduce inflammation

Scientists at St. Jude's Research Hospital discovered how mitochondria and lysosomes work together to activate and deactivate regulatory T cells, which are crucial for controlling inflammation and immune responses. Their findings reveal metabolic and organelle signaling pathways that influence T cell function, with potential implications for treating autoimmune diseases and enhancing cancer immunotherapy.
