Viruses modify host cellular machinery to produce high amounts of viral progeny

The study, published in Nature Communications, shows a new mechanism whereby viruses modify cellular machinery so that it can better read the instructions in the genome of the invading virus.

Researchers receive $1.2 million Keck Foundation grant to find molecules for targeting the 'undruggable proteome'

The W.M. Keck Foundation has awarded a $1.2 million grant to medicinal chemistry and computational biology researchers at the University of Kansas and the University of Chicago focused on addressing a long-unresolved problem in biomedical research - finding molecules able to target the "undruggable proteome."

Inactivation of particular protein complex associated with Parkinson's and anxiety disorders

Inactivation of a particular protein complex that plays a key role in keeping genes switched off leads to nerve cells not producing enough essential neurotransmitters.

NRL fungal experiment to launch as part of NASA's scheduled Artemis I mission

An experiment prepared by the U.S. Naval Research Laboratory (NRL) will launch as part of NASA's scheduled Artemis I mission to orbit the moon Aug. 29.

Evolution can favor flexible proteins, research suggests

When you think of proteins – the enzymes, signaling molecules, and structural components in every living thing – you might think of single strands of amino acids, organized like beads on a string.

Study identifies novel neutrophil biomarkers of delayed recovery in COVID-19

Researchers map the proteomes of peripheral blood neutrophils isolated from hospitalized COVID-19 patients using high-resolution LC-MS.

Unconventional T cells influence immune responses in the lymph nodes

Lymph nodes trigger very different immune responses – depending on which body tissue they are connected to. Special T cells are responsible for this newly discovered relation.

UCI study uncovers key insights into 'parasitic genes'

They are considered "parasitic genes." Even though they comprise over half of human DNA, much remains to be learned about them.

Common molecular tool for DNA labelling shows unexpected anticancer properties

Scientists at the UNC School of Medicine have made the surprising discovery that a molecule called EdU, which is commonly used in laboratory experiments to label DNA, is in fact recognized by human cells as DNA damage, triggering a runaway process of DNA repair that is eventually fatal to affected cells, including cancer cells.

SARS-CoV-2 breakthrough infection induces virus-specific nasal T-cells

A new study reports that hybrid immunity induced by vaccination and previous infection induces SARS-CoV-2-specific tissue-resident T-cells in the nasal cavity.

Johns Hopkins Medicine researchers challenge the prevailing belief on how nasal cells process scent

Johns Hopkins Medicine researchers say they have evidence to potentially overturn a prevailing belief in a type of important signaling within cells.

Researchers visualize antigen-bound T-cell receptor at atomic resolution

T cells are our immune system’s customized tools for fighting infectious diseases and tumor cells. On their surface, these special white blood cells carry a receptor that recognizes antigens.

Researchers create novel mouse model for mapping protein communication between organs

Our many different organ systems are in constant communication with each other. During exercise, for example, muscles send out signals to fat and liver tissue to release their energy sources.

Innovative technology revels the impact of environmental conditions on RNA structures in living cells

The impact of environmental conditions on the dynamic structures of RNAs in living cells has been revealed by innovative technology developed by researchers at the John Innes Centre.

Scientists elucidate the structure of Type IV secretion system involved in antibiotic resistance

With antibiotic-resistant bacteria on the rise, scientists have been searching for ways to shut down the Type IV secretion system (T4SS), a protein complex on the outer envelope of bacterial cells that helps them to exchange DNA with neighboring bacteria and resist antibiotics.

KAUST bioscientists develop new method to study the bone marrow microenvironment in greater detail

Deep molecular analysis of the bone marrow microenvironment reveals that the cells regulating blood stem cell maintenance are more diverse than expected and have features likely to be conserved between species.

Intestinal tissue-resident lymphocytes regulate their activity depending on glucose availability

A new study led by Marc Veldhoen, group leader at the Instituto de Medicina Molecular João Lobo Antunes (iMM; Portugal) and Associate Professor at Faculdade de Medicina de Lisboa (FMUL) and published today in the scientific journal PNAS (Proceedings of the National Academy of Sciences of the United States of America) discovered that white blood cells that reside in the intestines, a specific group of immune cells called tissue-resident lymphocytes, use sugar as an energy source and have a faster metabolism than lymphocytes that circulate in the blood.

Study paves new way to develop a predictive biomarker for TRAIL therapy

A cytokine named TRAIL binds to TRAIL receptors and kills cancer cells, but not normal cells. Therefore, various anticancer drugs targeting TRAIL receptors have been developed and gained great attention as a promising cancer therapeutics, but a certain population of cancer patients does not respond to the therapy.

In monkeys, spike-based vaccines produce some immunity based on CD8 T-cells

Scientists evaluate the role of CD8+ T-cells in vaccine protection against SARS-CoV-2 infection in rhesus macaques.

Why is COVID-19 more severe in people older than 50?

A new study reports that the reduced efficiency of the immune response against SARS-CoV-2 could be due to the reduced diversity of both B- and T-cells.
