Deleting a liver enzyme lowers the health risk of sweet treats (at least in mice)

Hepatic insulin resistance, caused by diets high in sugar and fat, can lead to type 2 diabetes. Researchers found that the Elovl6 gene plays a key role in hepatic insulin resistance. Deleting Elov6 in liver cells causes a rise in a specific ceramide lipid that protects mice from hepatic insulin resistance due to excessive dietary sugar. The findings could help efforts to find a targeted treatment for the condition.

'Instant liver, just add water'? Not quite, but a better way to grow multiple organs

Pluripotent stem cells can be used to make experimental models of organ systems, but current techniques often produce models that bear limited resemblance to true organs. Researchers developed an improved method to make a sophisticated three-dimensional organoid model of the liver, pancreas, and bile ducts. The model may help researchers understand how these organs form and how genetic mutations can lead to diseases in these organs.

First cell map of developing human liver reveals how blood and immune system develops

In a world first, scientists have created the human developmental liver cell atlas that provides crucial insights into how the blood and immune systems develop in the fetus. It maps changes in the cellular landscape of the developing liver between the first and second trimesters of pregnancy, including how stem cells from the liver seed other tissues to support the high demand for oxygen needed for growth.

New mechanism in the liver helps prevent invasive fungal infections

An expert in intravital microscopy is making breakthroughs in invasive fungal infections. He has discovered a pathway by which liver macrophages capture fungi before dissemination to target organs like the brain. This not only provides an explanation as to why individuals with liver disease have enhanced risk of fungal infection, but also points to therapeutic options to prevent these infections, which kill 1.5 million people annually.
