Bystander T cells can steal the show in resolving inflammation

New research reveals that bystander cell accumulation antagonizes rather than abets cell-killing by specific CTLs, curbing inflammation. The finding is noteworthy because that chief anti-inflammatory role has been traditionally ascribed to what are called regulatory T cells, or ‘Tregs,’ which dampen autoimmune responses. The new study challenges this notion and suggests alternate mechanisms can also […]

Higher-dose RT lowers risk of recurrence but does not improve survival for men with prostate cancer

High-dose radiotherapy did not improve survival for men with intermediate-risk prostate cancer but did improve biochemical control and rates of distant metastases, when compared to standard radiotherapy. Men who received higher-dose radiotherapy underwent fewer salvage therapies to control tumors that had grown larger or had spread to another body site; however, they also experienced more […]

Older adults who have slower walking speeds may have increased risk for dementia

Because there’s currently no cure for dementia, it’s important to know about risk factors that may lead to developing it. For example, researchers have learned that older adults with slower walking speeds seem to have a greater risk than those with faster walking speeds. Recently, researchers have learned more about changes in walking speed, changes […]
