New, Effective Method can Make Rare Cell Types and Disease Patterns Visible in Tissue

The human body contains more than 30 trillion cells. Until recently, the sheer number of cells in the organism meant that approaches to understanding human diseases and developmental processes based on the analysis of single cells were a futuristic vision.

Study identifies 238 amyloid toxicity protective or activator genes

An international study led by the Molecular Physiology Laboratory at the UPF Department of Medicine and Life Sciences (MELIS) identifies new genes that modulate the toxicity of the protein β-amyloid, responsible for causing Alzheimer's disease.

New perspective on how immune cells perceive viruses and other threats

A textbook chapter on the immune system may need to be revised as a result of a new study from Aarhus University.

New model describes the enormous range of DNA in nature

Why neutral sequences, frequently referred to as “junk DNA,” are not removed from the genomes of living things in nature and persist there even millions of years later is a scientific mystery that could have a possible answer according to a new model created at Tel Aviv University.

Tissue inflammation altered by “natural killer” immune cells

The discovery of a previously unknown role of “natural killer” (NK) immune cells by Melbourne researchers has increased the current understanding of how the immune system is controlled to prevent disease.

Genetic variants that increase the risk of ADHD identified

Why are some people diagnosed with ADHD while others are not? And when is the seed of ADHD sown, in life or the womb?

Technology development could help expand usefulness of Raman microscopy

Researchers have developed a Raman microscope that can acquire information hundreds of times faster than a conventional Raman microscope.

Chemosynthesis fuels ocean microbes in the darkest depths

A world first study reverses the idea that the bulk of life in the ocean is fuelled by photosynthesis via sunshine, revealing that many ocean microbes in fact get their energy from hydrogen and carbon monoxide.

New hexameric structure of the protein triggering antibiotic resistance discovered

All living organisms require DNA replication to ensure the genetic integrity of the following generation. On the other hand, bacteria have the ability to horizontally transfer genetic information to other bacteria.

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.

Experimental optimization of prime editing to achieve high efficiency

Genome editing technologies have enormous potential for treating genetic diseases. Techniques like the extensively used CRISPR/Cas9 gene scissors target the source of the disease directly in the DNA.

Clinically approved fungal vaccine protects against fungal infections

A new vaccine developed by the University of Georgia might be the first clinically approved immunization to safeguard against invasive fungal infections, which are becoming more common as antifungal drug resistance grows.

Digital microbe database unlocks patient response to treatment

Scientists at the University of Galway, in collaboration with APC Microbiome Ireland, a world-class SFI Research Centre, have developed a database of over 7,000 digital microbes, allowing computer simulations of how drug treatments operate and how patients may respond.

Preventing protein-protein interactions with a new tool

Proteins constantly interact with one another inside cells to perform various tasks. Blocking the binding of two or more proteins appears as a potential treatment for some diseases where these functions are altered.

Acute infection disrupts the healthy balance between the good and bad gut microbes

Rutgers researchers examined the impact of COVID-19 on patients’ microbiomes, the group of microbes that live in and on the human body.

European project promotes top-notch research in biochemistry and biophysics

TWIN2PIPSA, a new European project funded with €1.2 million, will support leading research and intensive training in the biochemistry and biophysics of protein folding, with implications and applications in biomedicine and biotechnology.

Role of p53-mediated metabolism in preventing genomic instability

The gene that codes for the protein p53 is most likely the most significant factor in defending human cells against DNA-damaging agents that cause cancer. The protein permits cells to repair DNA damage and so prevents the formation of malignancies, earning it the nickname “guardian of the genome.”

Quantifying microanatomical tissue structures without human intervention

Scientists at Weill Cornell Medicine have created a computational method for mapping the architecture of human tissues in extraordinary detail. Their method guarantees to expedite research on organ-scale cellular interactions and could lead to strong new diagnostic strategies for a variety of disorders.

Rutgers researchers seek to develop technology for protein editing

Rutgers researchers are seeking to develop the technology to modify or "edit" protein molecules in the body-;an advance that could spur major breakthroughs in human health.

An analysis of old genes’ influence on sea anemones

For the neuronal cell types’ categorization as more complicated creatures, the genetic fingerprint of Nematostella vectensis—the sea anemone—reveals that the members of this evolutionarily very ancient animal phylum employ identical gene cascades.
