Improving the efficacy of cellular therapies

Researchers have gained a better understanding of the complexity of the environment in which T cells thrive and, by extension, the tolerance mechanisms of these cells which are an obstacle to cellular immunity. Published in Nature Communications, the new study was directed by Dr. Marie-Ève Lebel, a post-doctoral intern at the […]

Kang finds keys to control the ‘driver of cancer’s aggressiveness’

“Do not erase.” “Recycle me.” “Free to a good home.” Humans post these signs to indicate whether something has value or not, whether it should be disposed of or not. Inside our cells, a sophisticated recycling system uses its own enzymatic signs to flag certain cells for destruction — and […]

$14 million boost for Parkinson’s disease research

Two new grants totaling nearly $14 million over three years will jump-start research at UC Berkeley into the molecular and genetic causes of Parkinson’s disease, a neurodegenerative disorder that afflicts more than 1 million Americans, yet whose cause remains a mystery. The grants are among 21, for a total of […]

People with PTSD are facing hugely increased risk of dementia

As society ages, we have more and more people living with dementia. It is an incurable disease and we are sort of accepting it as a sad part of life. Your lifestyle, genes and some other factors influence the risk of dementia. And the goal for you is to reduce […]

Problems in synapse connection sites found in rare neurodevelopmental disorders

Researchers at Karolinska Institutet describe molecular and cellular consequences of unique genetic mutations affecting the CASK gene which has been implicated in various neurodevelopmental disorders. Notably, the results indicate differences in the development of presynapses of inhibitory neurons in individuals with specific mutations. The findings elucidate key mechanisms during early […]

Survivors of neonatal heart repair surgery face lifelong risk of kidney disease, high blood pressure

Babies who have life-saving surgery for congenital heart problems within the first month of life face a lifelong risk of chronic kidney disease and high blood pressure, according to new research led by University of Alberta pediatric specialists. “We know that kidneys, like all organs, have to last a lifetime,” said Catherine Morgan, […]

Antibiotic pre-treatment reduces joint inflammation

Tearing an anterior cruciate ligament (ACL) can be an excruciatingly painful injury. Nearly 50 percent of these patients will develop a secondary form of osteoarthritis, deemed post-traumatic osteoarthritis (PTOA). Researchers from Lawrence Livermore National Laboratory (LLNL) and the UC Davis Medical Center have found that treatment with antibiotics prior to the injury could reduce inflammation […]

Researchers develop tissue engineering platform technology for joint tissue regeneration

A research team led by Professor Kim Gyo-beom of Dongguk University's Department of Chemical and Biological Engineering has developed the latest technology for joint tissue regeneration via simultaneous delivery of therapeutic growth factors and adi-pose derived stem cells into the body. The work was published in the Journal of Controlled […]

On the Clock

How old are you for your age? Scientists who study ageing have begun to distinguish chronological age: how long it's been since a person was born, and so-called biological age: how much a body is “aged” and how close it is to the end of life. These researchers are uncovering […]

Maternal Stress During Pregnancy Linked to Infant Illness

Greater maternal stress during pregnancy is linked with significant increases in the number and variety of infant illness during the first year of life, independent of the level of stress after birth, according to a study led by researchers at UC San Francisco. The study, published in the Journal of […]

RNA Information Transfer Could Be Used in Repairing DNA

Genomes are routinely subjected to DNA damage. But most cells have DNA repair systems that enforce genome stability and, ideally, prevent diseases like cancer. The trouble gets serious when these systems break down. When that happens, damage such as unrepaired DNA lesions can lead to tumors, and genomic chaos ensues. […]

Stanford technology predicts the slow death of lithium-ion batteries

Batteries fade as they age, slowly losing power and storage capacity. As in people, aging plays out differently from one battery to another, and it’s next to impossible to measure or model all of the interacting mechanisms that contribute to decline. As a result, most of the systems used to […]

Fighting breast cancer with nanotech, immunotherapy

A team of scientists led by a researcher at the Case Western Reserve University School of Medicine is making strides to fight deadly metastatic breast cancer by combining nanotechnology with immunotherapy. Efstathios “Stathis” Karathanasis, an associate professor of biomedical engineering, is directing the novel technique—sending nanoparticles into the body to […]

Studying the human genome to understand the risk of autism

A team of researchers at CHU Sainte-Justine and Université de Montréal has succeeded in using bioinformatics to develop a statistical model to assess how the gain or loss of genetic material impacts the risk of autism. The results of this work are presented in the American Journal of Psychiatry. This […]

Why is COVID-19 more severe in men and elders?

The immune system usually mounts a strong immune response to infection by SARS-CoV-2, the virus that causes COVID-19. That defensive response, however, appears to be weaker in men and people over the age of 60, a study led by researchers at the University of Washington School of Medicine in Seattle has […]

Preserving Brain Tissue with Stem Cells

UT Health physicians use supercomputers to interpret results of traumatic brain injury clinical trial. Individuals with traumatic brain injuries, or TBIs, frequently experience the shrinking or atrophying of brain tissue near where the injury occurred, causing additional damage beyond the original harm. If this can be prevented, many could function […]

Seeing the eye like never before

Researchers are able to visualize the retina's function at the cellular level, which will help accelerate cures for blinding diseases. While there is no cure for blindness and macular degeneration, scientists have accelerated the process to find a cure by visualizing the inner workings of the eye and its diseases at […]

Mutation leading to biological changes may play role in cancer

A new study from McGill University’s Goodman Cancer Research Centre (GCRC) has revealed significant biological changes in mice expressing an activated, mutant form of the Estrogen Receptor alpha (ER alpha), shedding new light on the role of this important gene in development and cancer. Over-expressed in approximately 70 % of breast cancer cases, the Estrogen Receptor is often associated […]

Powerful push to use AI for cancer immunotherapy

For artificial intelligence (AI) tools being developed at Case Western Reserve University to have impact in the fight against cancer, they’re going to have to be validated in rigorous human clinical trials. That validation may be a step closer following two recent agreements among bioengineering pioneer Anant Madabhushi, a longtime […]
