NYU LANGONE HEALTH / NYU SCHOOL OF MEDICINE Among the most studied protein machines in history, mTORC1 has long been known to sense whether a cell has enough energy to build the proteins it needs to multiply as part of growth. Because faulty versions of mTORC1 contribute to the abnormal growth seen in cancer, drugs...

Deciphering the language of cells using observation chambers
Date:May 28, 2018 Source: Ecole Polytechnique Fédérale de Lausanne Summary: Researchers have developed an innovative label-free method for studying the behavior of single cells continuously and in real time. By placing a cell in a small chamber containing nanosensors and observing it over many hours, it is possible to identify the cell’s unique personality and understand...

What Are STAP Cells (Stimulus-Triggered Acquisition of Pluripotency)?
There has been a lot of clamor and hype surrounding stimulus-triggered acquisition of pluripotency (STAP) cells since their introduction to the research community in 2014. Read this post for a short, succinct summary of the scientific controversy surrounding STAP cells. Defining STAP Cells In this article: What Is It About Background of Stapcells The Controversy...

Receptor proteins that respond to nicotine may help fat cells burn energy
ANN ARBOR–The same proteins that moderate nicotine dependence in the brain may be involved in regulating metabolism by acting directly on certain types of fat cells, new research from the University of Michigan Life Sciences Institute shows. IMAGE: ILLUSTRATION OF THERMOGENESIS IN MICE BEIGE FAT CELLS IN RESPONSE ACETYLCHOLINE STIMULATION Previous research by LSI research assistant professor Jun Wu and others identified a new...

Scientists manipulate ‘satellite cells’ to speed healing
Muscle aches and pains, whether from stretching, strenuous exercise or just normal wear and tear, can put a crimp in your day, a limp in your step and be an actual pain in the neck. But no matter the severity, stem cells in the skeletal muscles called satellite cells play a key role in repairing...

New discovery explains why cells with identical genes perform unique jobs
Scientists have made a significant discovery that explains how and why the billions of different cells in our bodies look and act so differently despite containing identical genes. The discovery, made by a team from the Smurfit Institute of Genetics at Trinity College Dublin, applies to all complex animals, including humans. The team has discovered...

Older adults grow just as many new brain cells as young people
Researchers show for the first time that healthy older men and women can generate just as many new brain cells as younger people. There has been controversy over whether adult humans grow new neurons, and some research has previously suggested that the adult brain was hard-wired and that adults did not grow new neurons. This...

Cellular Footprints: Tracing How Cells Move
An engineered cell (green) in a fruit fly follicle (red), or egg case, leaves a trail of fluorescent material as it moves across a fruit fly egg chamber, allowing scientists to trace its path and measure how long it took to complete its journey.

Th17 cells could facilitate wider clinical use of adoptive Immunotherapy
Researchers at Medical University of South Carolina (MUSC) report that long-term expansion protocols for adoptive cancer immunotherapy does not compromise Th17 cells’ effectiveness against large tumors in the March 9.2017 issue of JCI insight. This is a significant finding because rapid expansion protocols (REPs) that are used to produce sufficient CD8+ T cell numbers for...
