ApoE4 from neurons plays a critical role in Alzheimer's disease

Of all the known genetic risk factors for late-onset Alzheimer's disease, the strongest is a gene for the protein called ApoE4.

Realistic model explores new treatments for brain tumors

Until now, the use of models to study the barrier that differentiates the circulatory and nervous systems has been either limited or extremely complex. ETH Zurich researchers have created a more accurate model that can also be used to effectively investigate new treatments for brain tumors.

Pets help improve the mental health and wellbeing of older people

Furry, finned, or feathered, our family pets come in all shapes and sizes. But while these friendly faces keep us company at home, it's a very different story for people in aged care – many of whom must relinquish their beloved pet as a condition of entry.

Role of probiotics and functional materials in the treatment of intestinal inflammation

Maintenance of sulfomucin is a key end point in the treatment of diarrhea and inflammatory bowel disease (IBD). However, the mechanism underlying the microbial sense to sulfomucin are poorly understood, and to date, there are no therapies targeting the secretion and maturation of sulfomucin in IBD. Considering the important role of gut microbiota in host immune regulation, maintain sulfomucin by modulating the gut microbiota is inspired.

New method for studying mitochondria using advanced imaging technology

Scientists at Scripps Research have developed an advanced imaging-based approach that provides a unique perspective on mitochondria, which are best known as the “powerhouses” of cells.

Adding antioxidants to cell cultures for efficient production of antibodies

Researchers at the Department of Chemical Engineering, Indian Institute of Technology, India, have investigated the effects of oxidative stress on the production of monoclonal antibodies (mAbs), and how antioxidants can alleviate this stress to improve their performance.

New approach to rapidly determine biological aging

Telomeres-;the caps at the ends of chromosomes that protect our genetic materials from the brunt of cellular wear and tear-;are known to shorten and fray over time.

How the immune response in the brain aggravates epilepsy

Biologists at the University of Iowa have conclusively connected epilepsy with the brain’s immune system.

Study reveals the mechanisms that prevent effective cancer cell death

Cancer is a disease driven by gene mutations. These mutated genes in cancer fall into two major categories: tumor suppressors and oncogenes. Mutations in tumor suppressor genes can allow tumors to grow unchecked – a case of no brakes – while mutations in oncogenes can activate cell proliferation, pushing the gas pedal all the way to the floor.

Extracts from two common wild plants block SARS-CoV-2 from entering human cells

Two common wild plants contain extracts that inhibit the ability of the virus that causes COVID-19 to infect living cells, an Emory University study finds.

A treatment strategy to hasten cancer cell death

Gene mutations are the cause of cancer. Tumor suppressors and oncogenes are the two main groups of these altered genes in cancer. Mutations in oncogenes can drive cell proliferation, pushing the gas pedal to the floor, whereas mutations in tumor suppressor genes can cause tumors to grow unchecked—a situation in which there is no control.

Identifying the molecular switch that regulates autophagy in plants

Autophagy, commonly known as “self-eating,” is a cellular quality control mechanism that relieves the cell of protein aggregates and damaged organelles. This system is inert under ordinary conditions and is only activated in the presence of persistent cellular stress.

Telomeres, mitochondria, and inflammation: Working in synergy to fight cancer

The telomeres, or ends of the chromosomes, increasingly shorten as people age. Recently, Salk researchers found that when telomeres are very short, they can still interact with the mitochondria, the cell’s powerhouses.

Psychological trauma related to HIV could make it difficult to end the AIDS epidemic

Failing to address the psychological trauma experienced by many older people living with HIV/AIDS will make it difficult, if not impossible, to end the epidemic, according to a Rutgers study.

Novel insight into how stress changes in dynamic social systems

Stress is ubiquitous in today's world and affects people's lives significantly. Past research has focused on how stress is transmitted between pairs of individuals and in small groups. In a new longitudinal study, researchers adopted a network perspective to examine how the distribution of stress in an individuals' social environment influences their appraisal of stress.

Understanding how tiny organisms thrive after wildfires

UC Riverside researchers have identified tiny organisms that not only survive but thrive during the first year after a wildfire. The findings could help bring land back to life after fires that are increasing in both size and severity.

Structure of amyloid fibers formed by the protein hnRNPDL-2 determined

Using high-resolution cryo-electron microscopy (cryo-EM), UAB researchers determined the structure of amyloid fibers formed by the protein hnRNPDL-2, which has been linked to limb-girdle muscular dystrophy type 3 and concluded that the protein’s inability to form amyloid ﬁbers, rather than aggregation, would be the cause of the disease.

Exploring how plants can adapt to accelerating aridity due to climate change

At a time when climate change is making many areas of the planet hotter and drier, it's sobering to think that deserts are relatively new biomes that have grown considerably over the past 30 million years.

Learning about cellular proteins through “snapshots” of translation

Pep-tRNAs, nascent polypeptides inside the ribosome that are covalently connected to transfer RNA, are engaged in a variety of cell processes, including gene expression, according to advances in molecular biology.
