Nuclear Softening Allows Cells to Move Into Dense Tissue, Encouraging Injury Repair

Using an enzyme inhibitor in meniscus cells, a Penn team was able to soften their nucleus and promote access to previously impassible areas. By softening a cell’s nucleus so that it can squeeze its way through dense connective tissues, a group of researchers believes they’ve demonstrated a new way to […]

Immune Cells Infiltrating Tumors May Play Bigger Cancer Role Than Previously Thought

Most traditional cancer therapies target either the tumor cells themselves or indiscriminately kill any rapidly dividing cell. New findings by researchers at University of California San Diego School of Medicine indicate that manipulating macrophages, a type of immune cell found abundantly in the tissues surrounding a tumor, could also be […]

NIH study shows genomic variation causing common autoinflammatory disease may increase resilience to bubonic plague

Researchers have discovered that Mediterranean populations may be more susceptible to an autoinflammatory disease because of evolutionary pressure to survive the bubonic plague. The study, carried out by scientists at the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health, determined that specific genomic variants that cause […]

New treatment for common form of muscular dystrophy shows promise in cells, animals

University of Alberta-led team develops synthetic molecule that stops production of toxic muscle-killing protein. Researchers have designed a potential new treatment for one of the most common forms of muscular dystrophy, according to a new study published in the Proceedings of the National Academy of Sciences. Toshifumi Yokota, professor of medical genetics […]

Why memory-forming neurons are vulnerable to Alzheimer's

When Alzheimer’s disease strikes, the entire brain doesn’t crumble at once. Instead, the mind unravels like grim clockwork, beginning with the telltale degradation of a group of brain cells in the entorhinal cortex. These so-called vulnerable neurons are responsible for shuttling experiences into memories. They are always the first to […]

Light drinking may protect brain function

Light to moderate drinking may preserve brain function in older age, according to a new study from the University of Georgia. The study examined the link between alcohol consumption and changes in cognitive function over time among middle-aged and older adults in the U.S. “We know there are some older […]

Researchers find on-off switch for inflammation related to overeating

Researchers at Yale have identified a molecule that plays a key role in the body’s inflammatory response to overeating, which can lead to obesity, diabetes, and other metabolic diseases. The finding suggests that the molecule could be a promising therapeutic target to control this inflammation and keep metabolic diseases in […]

Supercomputer Simulations Show How DNA Prepares Itself for Repair

It’s common knowledge that the human body consists of trillions of cells. The cell nucleus, which houses DNA, is under attack every second of every day by environmental and behavioral factors. Researchers from Harvard University and the University of Texas Medical Branch at Galveston (UTMB) recently used the Comet supercomputer at the San Diego […]

Engineered immune cells recognize, attack human and mouse solid-tumor cancer cells

A method known as CAR-T therapy has been used successfully in patients with blood cancers such as lymphoma and leukemia. It modifies a patient’s own T-cells by adding a piece of an antibody that recognizes unique features on the surface of cancer cells. In a new study, researchers report that […]

Neurons thrive even when malnourished

When animal, insect or human embryos grow in a malnourished environment, their developing nervous systems get first pick of any available nutrients so that new neurons can be made. In this process, called organ sparing, resources are preferentially delegated to the nervous system at the cost of less important organs […]

Genes affecting brains and brawn?

Genetic deletions associated with neurodevelopmental disorders also important for development elsewhere in the body. Genes located in “copy number variants” (CNVs) — parts of chromosomes that are missing in some individuals and duplicated in others — that are associated with neurodevelopmental disorders affect more than just brain development, according to […]

How cancer drugs find their targets

In the watery inside of a cell, complex processes take place in tiny functional compartments called organelles. Energy-producing mitochondria are organelles, as is the frilly golgi apparatus, which helps to transport cellular materials. Both of these compartments are bound by thin membranes. But in the past few years, research at […]

A focused approach to imaging neural activity in the brain

When neurons fire an electrical impulse, they also experience a surge of calcium ions. By measuring those surges, researchers can indirectly monitor neuron activity, helping them to study the role of individual neurons in many different brain functions. One drawback to this technique is the crosstalk generated by the axons […]
