A new study led by Cedars-Sinai and the University of California, San Francisco (UCSF), has determined that altering a cellular process can lead stem cells—cells from which other cells in the body develop—to die or regenerate.
The neocortex is the largest and most complex part of the brain and has long been considered the ultimate storage site for long-term memories.
Researchers at Washington University School of Medicine in St. Louis have found that a defect in an enzyme called APT1 interferes with the ability to secrete insulin, contributing to the development of Type 2 diabetes in people who are overweight or obese.
The skin is presumably the largest and one of the most versatile body organs. By providing a physical barrier, it protects our body from environmental assaults.
A newly published study from York University sheds light on the biological underpinnings in sex differences in obesity-related disease, with researchers observing “striking” differences in the cells that build blood vessels in the fatty tissue of male versus female mice.
A Ludwig Cancer Research study has discovered that the immune system’s surveillance of cancer can itself induce metabolic adaptations in the cells of early-stage tumors that simultaneously promote their growth and equip them to suppress lethal immune responses.
Obesity and metabolic diseases, such as diabetes, are extremely common in the United States.
A roundup of the latest medical discoveries and faculty news at Cedars-Sinai.
UT Southwestern immunologists have uncovered a key pathogenic event prompted by obesity that can trigger severe forms of nonalcoholic fatty liver disease and potential liver failure.
High levels of ammonia in tumors leads to fewer T cells and immunotherapy resistance in mouse models of colorectal cancer, new findings from the University of Michigan Rogel Cancer Center revealed. Researchers found that ammonia inhibits the growth and function of T cells, which are vital for anti-tumor immunity. The findings appear in Cell Metabolism.
Nerve cells need a lot of energy and oxygen. They receive both through the blood. This is why nerve tissue is usually crisscrossed by a large number of blood vessels.
Modern humans evolutionarily split from our chimpanzee ancestors nearly 7 million years ago, yet we are continuing to evolve.
A brief roundup of news and story ideas from the experts at UCLA Health.
Investigators from the Smidt Heart Institute at Cedars-Sinai have identified how biological pacemaker cells—cells that control your heartbeat—can “fight back” against therapies to biologically correct abnormal heartbeat rates.
Neuroscience graduate students at Children’s Hospital Los Angeles have developed an automated method that could save time and work for laboratories around the country by streamlining the process of identifying and mapping brain cells. Scientists want to understand how brain cells develop over time because the way these cells, called neurons, develop, influences how they function, or how they malfunction in neurodevelopmental disorders.
Female bees and wasps use modified ovipositors, formerly used in egg laying, to sting their attackers, including people.
Researchers from Boston Children’s Hospital and Harvard, using Argonne’s Advanced Photon Source, have characterized the structure of integrins, a type of cell surface receptor involved in the immune response.
Sometimes a name is just a name. Take bears, for example. In Yellowstone National Park, black bears outnumber their brownish-colored grizzly bear cousins, and in coastal areas of the Pacific Northwest, if someone says “brown bear,” they mean grizzly bear. But not all brown bears are grizzly bears.
Climate change, rather than competition, played a key role in the ascendancy of dinosaurs through the Late Triassic and Early Jurassic periods.
