Thymus-derived hormone may suppress age-related inflammation and boost cancer therapy
Chronic, low-grade inflammation in the body—a phenomenon known as "inflammaging" because it increases with age—has been linked to many of today's leading causes of illness and death, including cancer, heart disease, metabolic conditions and neurodegenerative diseases. But scienti
This sugar-coated therapy boosted survival against deadly brain cancer by 50% in mice
A new experimental treatment may have found a way to outsmart glioblastoma’s toughest defense: the blood-brain barrier. Researchers used sugar-coated nanoparticles to ferry genetic instructions that restore a key tumor-suppressing protein directly into brain cancer cells. In mous
Brain's immune cells put the brakes on out-of-control circuits in mouse model of Alzheimer
Researchers at Trinity College Dublin have discovered that microglia—the main immune cells of the brain—play a critical role in maintaining the stability of neuronal networks in Alzheimer's disease. Crucially, this suggests treatments that indiscriminately suppress these cells co
Best treatment for multiple sclerosis may be antivirals
Low levels of replicating Epstein-Barr viruses might be the main driver of the autoimmune condition multiple sclerosis. This may mean that targeting them would be as effective as suppressing the immune system, with fewer side effects

New role of PTGES3 uncovered in liver cancer growth and immune evasion
A research team led by Prof. Wang Hongzhi at the Hefei Institutes of Physical Science, Chinese Academy of Sciences, has found a novel role of prostaglandin E synthase 3 (PTGES3) in liver cancer, revealing how it drives both tumor growth and immune suppression.
Kidney cancer gene reveals an unexpected weakness and a new path for treatment
A common genetic mutation that helps some kidney cancers survive may also expose an unexpected weakness, one that MUSC Hollings Cancer Center researchers hope to transform into a new treatment strategy. In a study published in Cancer Research, Aguirre de Cubas, Ph.D., and colleag
