8 Personalized Cancer Vaccine Prevents Skin Cancer Recurrence in Trial¶

Merck and Moderna announced early phase 3 trial results showing their personalized cancer vaccine Intismeran, combined with Keytruda immunotherapy, extended disease-free survival in high-risk melanoma patients compared to Keytruda alone. The mRNA-based vaccine sequences individual patient tumors to direct immune system targeting. Over 1,000 patients participated; full results remain unpublished and peer review pending.

Phase 3 trial involved 1,000+ patients with high-risk stage 2, 3, or 4 melanoma
Intismeran (personalized vaccine) + Keytruda reduced risk of disease spreading
Uses mRNA technology targeting individual tumor DNA
Full results not yet published or peer-reviewed
Testing underway for lung, bladder, and kidney cancers

7.5 Genetic Study Reveals 1,000+ Sex-Linked Immune Switches Explain Female Autoimmune Disease Vulnerability¶

Researchers identified over 1,000 genetic switches that function differently in female versus male immune cells, explaining why women are far more vulnerable to autoimmune diseases. Female immune cells show greater genetic activity in inflammatory pathways, providing stronger infection defense but increasing autoimmune disease susceptibility.

7 AI-designed intrabodies open potential treatments for neurodegenerative diseases¶

University of Essex researchers developed AI-designed intrabodies—antibody fragments engineered to function inside human cells—with potential applications for Alzheimer's, Parkinson's, Huntington's disease, and motor neurone disease. Using Nobel Prize winner David Baker's AI protein redesign software, researchers converted 672 antibodies into stable intrabodies. Research published in Nature Communications with molecules made freely available to scientists.

7 Schizophrenia linked to widespread synaptic loss with asymmetric brain damage¶

A brain imaging study of 122 participants found that schizophrenia is characterized by widespread loss of synapses across frontal and temporal regions, with particularly pronounced loss in the left hemisphere. The synaptic loss pattern, measured via PET imaging, does not match volume changes seen on standard MRI, suggesting separate biological processes underlie the disease.

Study of 29 schizophrenia patients and 93 healthy controls using PET imaging
Widespread synaptic loss in frontal, temporal, memory, and emotion-related brain regions
Left hemisphere showed considerably greater synaptic loss than right
Brain regions with greatest losses contain high serotonin, GABA, and glutamate receptors

7 Brain's frontoparietal cortex dynamically adapts information routing¶

University of Iowa neuroscientists discovered that the frontoparietal cortex, the brain's decision-making hub, dynamically adjusts its connectivity with other brain regions based on task requirements rather than maintaining fixed connections. Using computational modeling and brain imaging, researchers found the cortex reorganizes in real-time to filter and prioritize information, functioning like an air traffic controller.
