Engineering Non-immune Cells to Kill Cancer Cells

But researchers have recently used T-cells engineered in the laboratory to combat tumours. Modified to include additional functions, these immune cells can hunt down and kill cancer cells. Unfortunately, however, such immune cell therapies can have significant side-effects. On top of that, the production of modified T-cells is technically challenging.

First Draft cell Atlas of the Small Intestine

This census, published in Nature, comprises a first-draft atlas of the small intestine's cellular composition, providing a reference for studying the biology of a host of conditions affecting or involving the gut, such as inflammatory bowel disease, cancers of the small intestine, celiac disease, and food allergies. The study also enhances

Newly discovered microRNA regulates mobility of tumor cells

During an embryo's development, epithelial cells can break away from the cell cluster, modify their cell type-specific properties, and migrate into other regions to form the desired structures there. This process, which is known as an epithelial-mesenchymal transition (EMT), is reversible and can also proceed in the direction from mesenchymal

Cells Induce Inflammation Upon Detection of Cytoplasmic DNA

The presence of free DNA in the cytoplasm activates two distinct defense measures. The first is an antiviral immune response, mediated by induction of the synthesis and secretion of immunostimulatory messenger molecules called interferons. The second is a classical inflammatory reaction, which elicits symptoms such as fever, and localized swelling

Brain Cells Die in Alzheimer’s and FTD

In the brain, LSD1 (lysine specific histone demethylase 1) maintains silence among genes that are supposed to be turned off. When the researchers engineered mice that have the LSD1 gene snipped out in adulthood, the mice became cognitively impaired and paralyzed. Plenty of neurons were dying in the brains of

A Tubular Structure to Stop Cell Growth

Some of the treasures of Easter Island are invisible. In the 1960s, researchers discovered a bacterium that produces a compound with potent anti-fungal properties. They called it rapamycin, from the island's native name Rapa Nui. Although evolutionarily distant, fungi and mammals share much of the basic biochemistry that drives cellular
