Adults harbor lots of risky autoreactive immune cells, study finds
Even though self-targeting immune cells remain prolific in adults’ bloodstreams, some kind of internal emergency brake seems to prevent them from triggering autoimmune disease — usually.
Scientists find genetic signature enabling early, accurate sepsis diagnosis
Systemic inflammation after injuries or surgery can dramatically alter the activity of thousands of genes, but a new study shows that changes in just 11 of them are enough to detect the presence or absence of accompanying infection.
Ulcer-causing bacteria induces stomach stem cell growth in mice, researchers find
The findings could explain why H. pylori is a risk factor for gastric cancer, the researchers said.
Existing drug may treat the deadliest childhood brain tumor, Stanford-led study finds
A multicenter study has identified an FDA-approved medication that prolongs survival in mice with diffuse intrinsic pontine glioma, a brain tumor that now lacks chemotherapy treatments.
Jeffrey Goldberg to lead Stanford’s Department of Ophthalmology
Jeffrey Goldberg, who earned a doctorate and medical degree at Stanford, said he plans to leverage the university’s expertise in neuroscience, engineering and genetics to expand research in regenerative ophthalmology.
Scientists find way to monitor progress of stem cells after transplantation into brain
The ability to detect successful engraftment, integration and function of human cells implanted into the brain of a living animal could potentially speed stem-cell therapies’ path to clinical use.
Foreign antibodies mobilize immune system to fight cancer, researchers find
A mouse’s T cells can be primed to attack and eliminate a malignant tumor by injecting antibodies from another mouse with resistance to the tumor, as well as by activating certain signaling cells, a study has found.
Photovoltaic retinal implant could restore functional sight, researchers say
So far, the researchers have tested the device only in animals, but a clinical trial is planned next year in France.
Brain tumor growth stimulated by nerve activity in the cortex, study finds
New research shows that high-grade gliomas, the deadliest human brain tumors, increase their growth by hijacking some of the machinery of neuroplasticity, which normally helps the brain form new synapses.
Patient-doctor ethnic differences thwart conversations on end-of-life care, study finds
Doctors struggle to start discussions with ailing patients about how they want to spend their last days, a survey finds. The upshot? Patients should bring up the topic themselves.
Leading the Biomedical Revolution
We are in the middle of a biomedical revolution more profound and far-reaching than the industrial and digital revolutions that made it possible.
A Legacy of Innovation
Stanford Medicine's unrivaled atmosphere of breakthrough thinking and interdisciplinary collaboration has fueled a long history of achievements.
