Study finds path for addressing Alzheimer’s blood-brain barrier impairment

MIT researchers pinpoint mechanism and demonstrate that drugs could help. By developing a lab-engineered model of the human blood-brain barrier (BBB), neuroscientists at MIT’s Picower Institute for Learning and Memory have discovered how the most common Alzheimer’s disease risk gene causes amyloid protein plaques to disrupt the brain’s vasculature and […]

Blocking brain signals detected in the kidney could help unlock future treatments for kidney failure, heart disease, and stroke

Scientists have discovered an important cell signaling pathway in the kidney which if stopped, could hold the key to treating chronic kidney disease as well as other deadly conditions, including heart attack and stroke. The pathway was already known to exist in the brain, where it helps to maintain the […]

Study: Neurons can shift how they process information about motion

Our brains use various reference frames—also known as coordinate systems—to represent the motion of objects in a scene. Some coordinate systems are more useful than others for representing information. To represent a location on Earth, for example, we might use an Earth-centered coordinate system such as latitude and longitude. In […]

Transparent fish reveal the subtle, cellular dance in which sensory organs take shape

We owe a great deal to the hair cells in our inner ear—without them we couldn’t detect sounds or take five steps without tripping. Moreover, these cells happen to be a useful model for biologists who want to understand how tissues self-organize into complex shapes during embryonic development. The cells’ […]

Diluting blood plasma rejuvenates tissue, reverses aging in mice

In 2005, the University of California, Berkeley, researchers made the surprising discovery that making conjoined twins out of young and old mice — such that they share blood and organs — can rejuvenate tissues and reverse the signs of aging in the old mice. The finding sparked a flurry of research […]

Evidence of a Senescent Cell Population for which Elimination Might be Problematic

Senescent cells accumulate throughout the body with age. They are constantly created and destroyed throughout life, but the balance between creation and destruction is upset with age, leading to an accumulated burden of cellular senescence. These cells secrete a potent mix of signals that produce chronic inflammation, disrupt tissue structure and cell function, and encourage […]

Stress Granules are Required for Calorie Restriction Induced Longevity

The formation of stress granules in cells is an interesting topic. As the name might suggest, this behavior emerges in cells undergoing stress, such as lack of nutrients, heat, cold, and so forth. Stress granules are transient structures that form within cells, made up of a wide variety of biomolecules that are packed […]

Loss of Visual Acuity Correlates with Dementia Risk

Many aspects of aging correlate with one another, even those with quite different underlying mechanisms and proximate causes. The various forms of root cause damage that result in the aging process, as well as their downstream consequences, all interact with one another. So whether or not any specific correlation teaches us anything […]

Putting ‘Super’ in Natural Killer Cells

Using induced pluripotent stem cells (iPSCs) and deleting a key gene, researchers at University of California San Diego School of Medicine have created natural killer cells — a type of immune cell — with measurably stronger activity against a form of leukemia, both in vivo and in vitro. The findings were published in […]

Helping damaged nerves to re-grow

Severed nerve tracts are very difficult to treat. If at all, the damage so far can only be repaired through complex operations. At the Max Planck Institute for Polymer Research, we have developed materials that stimulate damaged nerves into growth. Results from initial tests on mice show that nerve tracts […]

Human embryo-like model created from human stem cells

Scientists from the University of Cambridge, in collaboration with the Hubrecht Institute in The Netherlands, have developed a new model to study an early stage of human development using human embryonic stem cells. The model resembles some key elements of an embryo at around 18-21 days old and allows the […]

‘Terminator’ protein halts cancer-causing cellular processes

Essential processes in mammalian cells are controlled by proteins called transcription factors. For example, the transcription factor HIF-1 is triggered by a low-oxygen situation to cause the cell to adapt to decreased oxygen. Transcription factors operate in healthy cells, but cancer cells can co-opt transcription factors such as HIF-1 into […]

How Young Embryos Conduct Quality Control

The first few days of embryonic development are a critical point for determining the failure or success of a pregnancy. Because relatively few cells make up the embryo during this period, the health of each cell is vital to the health of the overall embryo. But often, these young cells […]

Virginia Tech veterinary neurologist helps establish shared 'life history' of brain cancer in dogs and people

Humans and dogs share many aspects of their lives: food, homes, and a deep bond of mutual affection. Although these common bonds bring joy and comfort, one connection between the two species is decidedly not positive. Both dogs and humans are uniquely susceptible to a devastating, aggressive brain tumor referred […]

Modeling neuronal cultures on 'brain-on-a-chip' devices

For the past several years, Lawrence Livermore National Laboratory (LLNL) scientists and engineers have made significant progress in development of a three-dimensional “brain-on-a-chip” device capable of recording neural activity of human brain cell cultures grown outside the body. Now, LLNL researchers have a way to computationally model the activity and structures of neuronal communities […]

Scientists generate early stem cells that form human placenta

Despite researchers’ efforts to understand pregnancy — both healthy and high-risk — the human placenta remains something of a mystery. Tissue samples are nearly impossible to obtain until after birth, making it difficult to study the placenta’s role in pregnancy complications. Now, scientists at Washington University School of Medicine in […]

Human eggs prefer some men’s sperm over others, research shows

Human eggs use chemical signals to attract sperm. New research from Stockholm University, Manchester University NHS Foundation Trust and The University of Manchester shows that eggs use these chemical signals to “choose” sperm. Different women’s eggs attract different men’s sperm – and not necessarily their partners. Humans spend a lot […]

Cancer cells adapt to lack of key nutrient, posing potential problems for drugmakers: U of T study

Cancer can adapt its metabolism in a way that could overcome lipid-focused therapies being developed by drug companies, a University of Toronto study has found. “Several clinical trials have failed because metabolism is such an adaptive process by which cancer cells gain drug resistance,” says Michael Aregger, a co-lead author and research associate […]
