In order for cancer to grow and spread, it has to evade detection by our immune cells, particularly specialized “killer” T cells. Salk researchers led by Professor Susan Kaech have found that the environment inside tumors (the tumor microenvironment) contains an abundance of oxidized fat molecules, which, when ingested by the killer T cells, suppresses their ability to kill cancer cells. In a vicious cycle, those T cells, in need of energy, increase the level of a cellular fat transporter, CD36, that unfortunately saturates them with even more oxidized fat and further curtails their anti-tumor functions.

The discovery, published online in Immunity on June 7, 2021, suggests new pathways for safeguarding the immune system’s ability to fight cancer by reducing the oxidative lipid dama...

Researchers discover an unexpected link between DNA winding and metabolism in the gut to ameliorate aging. Our genetic material is stored in our cells in a specific way to make the meter-long DNA molecule fit into the tiny cell nucleus of each body cell...

Using a new 3D printing process, University of Nottingham researchers have discovered how to tailor-make artificial body parts and other medical devices with built-in functionality that offers better shape and durability, while cutting the risk of bacterial infection at the same time.

Study lead, Dr Yinfeng He, from the Centre for Additive Manufacturing, said: “Most mass-produced medical devices fail to completely meet the unique and complex needs of their users. Similarly, single-material 3D printing methods have design limitations that cannot produce a bespoke device with multiple biological or mechanical functions.

“But for the first time, using ...

Single treatment provides patients with rapid, lasting antidepressant effects. A single, one-hour treatment that involves breathing in a mixture of oxygen and nitrous oxide — otherwise known as laughing gas — significantly improved symptoms in people with treatment-resistant depression, according to new data from researchers at Washington University School of Medicine in St. Louis and the University of Chicago.

In a phase 2 clinical trial...
