Deleting a gene prevents Type 1 diabetes in mice by disguising insulin-producing cells

Removing a gene from the cells that produce insulin prevents mice from developing Type 1 diabetes by sparing the cells an attack from their own immune system, a new UW–Madison study shows. The cellular sleight of hand may suggest ways to prevent Type 1 diabetes in high-risk individuals, as well […]

Cellular train track deformities shed light on neurological disease

A new technique allows researchers to test how the deformation of tiny train track-like cell proteins affects their function. The findings could help clarify the roles of deformed “microtubules” in traumatic brain injuries and in neurological diseases like Parkinson’s. Joint press release by Hokkaido University and the National Institute of […]

Parents modeling physical activity help kids with developmental disabilities improve motor skills

It’s a self-perpetuating cycle: Kids with developmental disabilities face challenges in building motor skills, which makes them less able to participate in routine physical activity, which gives them less opportunity to practice those same motor skills. But parents can make a big difference by modeling and supporting physical activity in […]

Old human cells rejuvenated with stem cell technology

Old human cells return to a more youthful and vigorous state after being induced to briefly express a panel of proteins involved in embryonic development, according to a new study by researchers at the Stanford University School of Medicine. The researchers also found that elderly mice regained youthful strength after their […]

A critical enzyme for sperm formation could be a target for treating male infertility

While some of our body’s cells divide in a matter of hours, the process of making sperm, meiosis, alone takes about 14 days from start to finish. And fully six of those days are spent in the stage known as the pachytene when pairs of chromosomes from an individual’s mother […]

What determines our lifespan?

There are so many anti-aging products around these days that claim to prevent the aging process. Their effectiveness aside, do you know that the average lifespan of Japanese people has increased by more than 30 years over the past century? Of course, no other living thing has been able to […]

CAR Macrophages Go Beyond T Cells to Fight Solid Tumors

Chimeric antigen receptor (CAR) T cell therapy has been a game-changer for blood cancers but has faced challenges in targeting solid tumors. Now researchers from the Perelman School of Medicine at the University of Pennsylvania may have an alternative to T cell therapy that can overcome those challenges. Their research shows genetically […]

Scientists investigate why females live longer than males

An international team of scientists studying lifespans of wild mammals have found that, just like humans, females tend to live significantly longer than their male counterparts. The researchers looked at the lifespans of 101 different species, from sheep to elephants, and found that females lived an average of 18% longer […]

Finding the best method to grow bioengineered tissue for pulmonary research

Before scientists develop the bioengineered tissue of tomorrow for treating pulmonary diseases, they need to identify the best methods for growing tissue for artificial trachea and lungs in experiments today. A new Yale analysis does just that, determining which methods produce tissue cells that are most like the natural cells […]

Engineers model mutations causing drug resistance

Whether it is a drug-resistant strain of bacteria, or cancer cells that no longer react to the drugs intended to kill them, diverse mutations make cells resistant to chemicals, and “second generation” approaches are needed. Now, a team of Penn State engineers may have a way to predict which mutations […]

Trajectories of Exercise and Mortality in Late Life

Greater physical activity correlates well with lower mortality in later life. Given the way that human data is collected, and the way in which epidemiological studies are carried out, it is hard to determine causation, however. Is it that exercise is protective, or is it that more robust people both live longer and exercise […]

Stem Cells and Nerves Interact in Tissue Regeneration and Cancer Progression

Researchers at the University of Zurich show that different stem cell populations are innervated in distinct ways. Innervation may therefore be crucial for proper tissue regeneration. They also demonstrate that cancer stem cells likewise establish contacts with nerves. Targeting tumour innervation could thus lead to new cancer therapies. Stem cells […]
