The immune system in the uterus can regenerate after both uterus transplantation and bone marrow transplantation. This is shown by a new study from Karolinska Institutet. The new insights into how the uterine immune environment ...
Medical Xpress / Tuning T cells' cancer-killing power via an engineered hydrogel platform
Lymph nodes, considered the command centers of our immune system, often get swollen and stiff when fighting infection. Now, a UC Berkeley-led team of researchers has discovered that this mechanical change may help instruct ...
Medical Xpress / Anchoring a key immune molecule makes T cells hit harder
Researchers at the Kennedy Institute of Rheumatology have found that physically resisting the formation of an immunological synapse actually promotes a stronger immune response. The findings could help explain how immune ...
Medical Xpress / Overlooked brainstem pathway that controls human hands offers stroke therapy targets
Researchers have identified a network of connections linking the brainstem and spinal cord that helps control hand and arm movements, revealing an unexpected layer of the nervous system enabling people to grasp, hold, and ...
Medical Xpress / Immune cells in the brain may tune fertility hormones, animal study suggests
The kick-off signal for puberty begins in the brain. Specifically, in the hypothalamus, where specific neurons release a hormone that activates the hypophysis, at the base of the skull, which then releases other hormones ...
Medical Xpress / Power outages linked to more emergency hospital visits for older adults

Medical Xpress / Researchers trace brown fat to an unexpected embryonic source at the aorta
A team of scientists has identified an unexpected embryonic "starting point" for several brown-fat depots: a small cell niche around the dorsal aorta. Using a combination of time-controlled genetic lineage tracing and single-cell ...
Medical Xpress / Scan that makes prostate cancer cells glow could cut need for biopsies
An imaging test could safely halve the number of people who need a biopsy for suspected prostate cancer following inconclusive or reassuring results from an MRI scan, new research has found. Findings from the PRIMARY2 trial ...
Medical Xpress / High-fat diet-linked dysbiosis may send gut bacteria to the brain via vagus nerve
Gut dysbiosis caused by a high-fat diet can allow bacteria to move from the gut to the brain in mice, according to a new study by David Weiss and Arash Grakoui from Emory University, U.S., and colleagues published in the ...
