Medical Xpress / Supercentenarians have an abundance of cancer-killing immune cells
The human immune system has specialized cells called CD4 cytotoxic T lymphocytes (CD4 CTLs), which have been shown to kill tumor cells in some cancers. When a person gets sick, these cells multiply in a process called clonal ...
Medical Xpress / Gut bacteria may transform spinach, beets and plant iron into protective compounds
Researchers at Karolinska Institutet have discovered that gut bacteria can convert dietary nitrate and iron into protective molecules that may reduce the risk of cardiovascular and metabolic diseases. The study, published ...
Medical Xpress / Aging reprograms skin genetic activity and promotes inflammation, study reveals
As we age, the skin loses part of its ability to regenerate, heal wounds and maintain an effective barrier against the outside world. Among the causes of this deterioration is low-grade, persistent age-associated inflammation, ...
Medical Xpress / World's largest psilocybin brain-imaging study maps how context reshapes psychedelic effects
A landmark five-year study by Monash University has found psychedelics reorganize brain patterns, giving clinicians powerful new insights into their therapeutic potential.
Medical Xpress / Human multi-organ chip tracks breast cancer spread to bone and lung
Cancer spreading beyond the primary tumor—a process known as metastasis—is responsible for at least two-thirds of cancer deaths. Drugs targeting metastatic progression have largely failed, in part because of the lack of predictive ...
Medical Xpress / Newly found 'immune organ' inside skull directs brain defense
