Summary: Researchers have uncovered a surprising link between gut immune cells and the brain in Alzheimer’s disease. In mice, antibody-producing B cells that normally reside in the gut were found migrating into brain border regions, influenced by chemokine signals from inflammatory brain cells. Feeding the animals a high-fiber diet restored gut immune balance and reduced frailty symptoms, even without lowering …

Summary: Researchers analyzing post-mortem brain tissue found two cell types altered in people with depression: excitatory neurons that regulate mood and stress, and microglia that manage inflammation. The findings highlight how depression is tied to measurable brain changes, not just emotional symptoms. By mapping gene activity alongside DNA regulation, scientists identified key cellular disruptions unique to depression. This breakthrough could …

A new study shows that blocking one protein can reprogram immune cells to fight cancer more powerfully, offering hope for next-generation therapies. Credit: Shutterstock Blocking a single protein boosts T cell metabolism and tumor-fighting strength. The discovery could lead to next-generation cancer immunotherapies. Scientists have identified a strategy to greatly enhance the cancer-fighting abilities of the immune system’s T cells. …

Researchers at UT Southwestern have uncovered a surprising way in which tumors exploit the body’s own immune system to grow unchecked. Their findings reveal a hidden interaction between a hormone and an immune receptor that switches cancer-fighting cells into cancer-supporting ones. Credit: Shutterstock A hormone-receptor interaction weakens immunity. Targeting it could fight cancer. Scientists at UT Southwestern Medical Center have …

Immune cells in the human brain may be critical to orchestrating the organ’s development in the womb because they trigger a dramatic increase in an important type of nerve cell, new research suggests. Estimates suggest that these key cells, known as inhibitory interneurons, make up some 25% to 50% of the neurons in the adult cortex, the wrinkled tissue that …

The biological cycle of our existence seems relatively straightforward: we’re born, we live, we die. The end. But when you examine existence at the cellular level, things get a bit more interesting. You, me, and all of the 108 billion or so Homo sapiens who’ve ever walked the Earth have all been our own constellation of some 30 trillion cells. …

Mice The mice used in this study were housed in pathogen-free facilities at the University of Chicago and Stanford University. All mice were housed in positively pressurized, individually ventilated cage racks and changed in biological safety cabinets. Cage supplies were sanitized using hot water (82 °C). Bedding and shredded-paper enrichment were autoclaved and cages were provided with irradiated food. Reverse Osmosis …

Microsoft Excel is testing a new AI-powered function that can automatically fill cells in your spreadsheets, which is similar to the feature that Google Sheets rolled out in June. You would use the “COPILOT” function followed by a natural language prompt and (optionally) specify the cells you want it to reference; the AI would then classify information, generate summaries, create …
