Blood vessel malformations originate in vein cells

In the condition known as cavernoma, lesions arise in a cluster of blood vessels in the brain, spinal cord or retina. Researchers from Uppsala University can now show, at molecular level, that these changes originate in vein cells.

Researchers reveal mechanisms that help C. difficile pathogen to survive in low oxygen levels

Researchers from ITQB NOVA, in collaboration with the Institut Pasteur in Paris, have shed light on the mechanisms that allow Clostridioides difficile, a pathogen that can only grow in oxygen-free environments, to be able to survive low oxygen levels.

Study sheds new light on how the immune system remembers viruses

For a person to acquire immunity to a disease, T cells must develop into memory cells after contact with the pathogen.

Researchers design a light-sensitive inhibitor that can control cell division and cell death

Ludwig-Maximilians-Universitaet (LMU) in Munich researchers have designed a light-sensitive inhibitor that can control cell division and cell death - and provides a promising approach for studies of essential cellular processes and the development of novel tumor therapies.

Study reveals how gene control mechanisms define the identity of developing brainstem neurons

A recent study at the University of Helsinki reveals how gene control mechanisms define the identity of developing neurons in the brainstem.

Tumor suppressor gene represses 'jumping genes'

About half of all tumors have mutations of the gene p53, normally responsible for warding off cancer. Now, UT Southwestern scientists have discovered a new role for p53 in its fight against tumors: preventing retrotransposons, or "jumping genes," from hopping around the human genome.

Cell biologists and bioimaging expert team up to solve fourth dimension secrets

Cell biologists at the University of Illinois at Urbana-Champaign and Bar-Ilan University at Israel and a bioimaging expert at the University of Central Florida are teaming up in what they hope may lead to a major breakthrough in understanding of the three-dimensional organization of the nucleus over time and their role in certain diseases.

Myeloid cells can suppress immune response, promote brain metastasis

Scientists have long believed that the brain protects itself from an aggressive immune response to keep down inflammation. However, that evolutionary control may work against it when a cancer cell attempts to spread to the brain, researchers at the University of Notre Dame have discovered.

Study shows how a genetic mutation causes common sleep syndrome

A new study by researchers at UC Santa Cruz shows how a genetic mutation throws off the timing of the biological clock, causing a common sleep syndrome called delayed sleep phase disorder.

Proton regulator of essential cancer miRNA discovered

MicroRNAs (miRNAs) are evolutionarily conserved small noncoding RNAs - bits of genetic code that serve as critical gene regulators in many aspects of biological processes important for human health.

UVA research sheds light on how cancer remodels our chromosomes

Cancer remodels the architecture of our chromosomes so the disease can take hold and spread, researchers at the University of Virginia have revealed.

Genome-wide screens reveal new helpful and harmful COVID-19 related genes

Researchers at Yale University and the Broad Institute of MIT and Harvard screened hundreds of millions of cells exposed to the COVID-19 and MERS viruses and identified dozens of genes that both enable the viruses to replicate in cells and also those that seem to slam the door on the virus.

Study better reveals the function and behavior of macrophages in cancer growth

Macrophages, cells that help engulf and destroy harmful organisms in the body, tend to be characterized as the Jekyll and Hyde of the immune system.

New versatile method to isolate individual cells with unique profiles

Researchers at Rice University and Baylor College of Medicine have developed a new method to isolate specific cells, and in the process found a more robust fluorescent protein.

Scientists devise new method to map HIV's sugary shield in unprecedented detail

Scientists from Scripps Research and Los Alamos National Laboratory have devised a method for mapping in unprecedented detail the thickets of slippery sugar molecules that help shield HIV from the immune system.

Study reveals new and essential details of how photoreceptors work

Moving around in the half-light is difficult but not impossible. To help us in this undertaking we have the rods, a type of light-sensitive cells (photoreceptors) present in the retina of vertebrates, capable of detecting very low lights which allow to move about even in poorly lit cellars or caves.

Neutrophils have more functions in the body than previously thought

Scientists at the Centro Nacional de Investigaciones Cardiovasculares have discovered that neutrophils, the most abundant cells of the innate immune system, have many more functions in the body than previously thought.
