The mechanisms regulating the balance between the formation of neurons and the maintenance of stem cells in the formation of the brain revealed

Anew study by the Neuronal Dynamics Research Group at UPF has elucidated the cellular and molecular mechanisms that regulate the balance between the differentiation of neurons and the maintenance of progenitor cells during the construction of the embryonic brain. The study, conducted in the zebrafish model, has been published in the journal Cell Reports. Anew … Read more

Pushing T cells down “memory lane” may improve cancer therapy – BIOENGINEER.ORG

Memphis, Tenn. – Scientists at St. Jude Children’s Research Hospital identified a molecular mechanism that in a preclinical study unlocked the promise of CAR T–cell therapy for treatment of solid tumors. The results were published today in the journal Nature. Credit: St. Jude Children’s Research Hospital Memphis, Tenn. – Scientists at St. Jude Children’s Research … Read more

Human cells take in less protein from a plant-based meat than from chicken – BIOENGINEER.ORG

Many people have now embraced the plant-based meat movement. Plants high in protein, such as soybeans, are common ingredients, but it’s been unclear how much of the nutrient makes it into human cells. In ACS ‘ Journal of Agricultural and Food Chemistry, researchers report that proteins in a plant-based substitute model were not as accessible … Read more

How tumors make immune cells ‘go bad’

Investigators from Cedars-Sinai Cancer have discovered that cancerous tumors called soft-tissue sarcomas produce a protein that switches immune cells from tumor-attacking to tumor-promoting. The study, published today in the peer-reviewed journal Cell Reports, could lead to improved treatments for soft-tissue sarcomas. The researchers focused on the tumor microenvironment — an ecosystem of blood vessels and … Read more

New research helps to better understand the basic biology of nerve cells

Scientists are starting to understand the precise workings of a type of gene that, unlike other genes, does not code for proteins – the building blocks of life. New research led by the University of Bath shows the mechanism by which genes coding for a subset of long non-coding RNA (lncRNA) interact with neighboring genes … Read more

Biologists freeze animal cells for preservation

At first glance, you’d hardly call it a zoo. But these tanks lined up in this research complex are preserving the cells of animals – some endangered. “The Frozen Zoo is the oldest collection of living cells, both skin cells, and reproductive cells,” Marlys Houck, the curator at the Frozen Zoo, said. “With those cell … Read more

Fluorescence microscopy shows how living cells form vesicles to transport cargo like growth factors – BIOENGINEER.ORG

BIRMINGHAM, Ala. – Cells have a clever way to transport cargos like growth factors across the cell membrane and into the cell. It is called clathrin-mediated endocytosis. Molecules of the protein clathrin gather on the inside of the cell membrane, and they deform the membrane to make what looks like a pit as seen from … Read more

New way of generating insulin-producing cells — ScienceDaily

Researchers at the Karolinska Institutet in Sweden show how a molecule that they have identified stimulates the formation of new insulin-producing cells in zebrafish and mammalian tissue, through a newly described mechanism for regulating protein synthesis. The results are published in Nature Chemical Biology. “Our findings indicate a new potential target for treating diabetes, in … Read more

New designer cells could advance treatments for illness and disease

ACS Nano 2022″ width=”500″ height=”347″/> Credit: ACS Nano 2022 Artificial cells have been engineered to mimic the natural characteristics of biological cells in a new study from Imperial College London. Scientists from the Departments of Chemical Engineering and Chemistry have developed a way to engineer artificial cells that mimic how biological cells behave in response … Read more

Biochemists use enzymes to change how brain cells communicate with each other – BIOENGINEER.ORG

As you’re reading this sentence, the cells in your brain, called neurons, are sending rapid-fire electrical signals between each other, transmitting information. They’re doing so via tiny, specialized junctions between them called synapses. As you’re reading this sentence, the cells in your brain, called neurons, are sending rapid-fire electrical signals between each other, transmitting information. … Read more
