Losing a productive type of beta cell may contribute to the development of diabetes

Multiple types of beta cells produce insulin in the pancreas, helping to balance blood sugar levels. Losing a particularly productive type of beta cell may contribute to the development of diabetes, according to a new study by Weill Cornell Medicine investigators.

Common commensal gut bacterium uses phase separation of Rho factor to thrive in the mammalian gut

The common commensal gut bacterium Bacteroides thetaiotaomicron uses phase separation of the transcription termination factor Rho to colonize and thrive in the mammalian gut, according to a new study in mice.

Potential approach to improve solid tumor T cell therapy

Researchers at the Perelman School of Medicine at the University of Pennsylvania have been working on a preclinical study that focuses on a new strategy that uses a “one-two punch” to assist T cells in attacking solid tumors.

Highlighting a potential sex‐specific precision immunotherapy strategy

Immunotherapy is an effective form of treatment for various types of cancer. However, its effect on pancreatic cancer is restricted and varies between men and women. Karolinska Institutet scientists have observed a possible explanation for this gender difference.

Unique region of the brain's cortex used when visually navigating an area by foot

Using vision to efficiently move through an area by foot uses a unique region of the brain's cortex, according to a small study funded by the National Eye Institute.

Using PET and electron microscopy to generate 3D maps of mitochondrial networks in lung tumors

Scientists have long known that mitochondria, the "powerhouses" of cells, play a crucial role in the metabolism and energy production of cancer cells.

Influence of molecular component of caffeine on gut health

Certain microbes are considered to play a role in the development of inflammatory disorders such as inflammatory bowel disease (IBD).

Study reveals the cellular composition and circuit organization of the locus coeruleus

A small nucleus in the brainstem called locus coeruleus (literally the "blue spot,") is the primary source of a major neuromodulator, norepinephrine (NE), an important mediator of the 'fight or flight' response in animals. However, very little is known about the local connections of this small albeit critically important group of neurons.

High doses of sucralose limit T cell proliferation and differentiation

Scientists at the Francis Crick Institute have found that high consumption of a common artificial sweetener, sucralose, lowers activation of T-cells, an important component of the immune system, in mice.

First molecular images of olfaction sets the stage to create novel smells

Breaking a longstanding impasse in our understanding of olfaction, scientists at UC San Francisco (UCSF) have created the first molecular-level, 3D picture of how an odor molecule activates a human odorant receptor, a crucial step in deciphering the sense of smell.

New therapeutic approaches to treat autoimmune diseases using a metabolite

Researchers have revealed the modulatory effect of the anti-inflammatory metabolite itaconate on T helper and T regulatory cells, which may lead to new therapeutic approaches to treating some autoimmune diseases.

Mesophotic coral reefs function differently than their shallower counterparts, study shows

In a paper published today in Current Biology, researchers from the California Academy of Sciences Hope for Reefs initiative, along with Brazilian collaborators from the University of São Paulo, Federal University of Espírito Santo, and the Instituto Nacional da Mata Atlântica, show that mesophotic coral reefs function much differently than their shallower counterparts and are unlikely to offer a refuge for shallow water fishes trying to escape climate-change driven warming on the ocean's surface.

High correlation between the product of a gene in the majority of cancers

The product of a gene expressed in most cancers, including the most prevalent type of head and neck cancer, has been linked to elevated levels of white blood cells that produce antibodies inside tumors, according to researchers at the University of California San Diego School of Medicine and UC San Diego Moores Cancer Center.

TurboID-based proximity labeling in meiotic cells of Arabidopsis thaliana

During meiosis, reshuffling of genetic information between homologous chromosomes through meiotic recombination creates variable gametes and hence genetic variation in offsprings.

Gut microbiome may modulate the efficacy of CAR-T cell cancer immunotherapy

Scientists from German Cancer Research Center (DKFZ), together with colleagues from Germany, Israel, and the USA, have found that the gut microbiome may modulate the efficacy of CAR-T cellular immunotherapy CAR-T cells in patients with B cell lymphomas.

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.

Effective backup mechanism ensures efficient antimicrobial responses in humans

In the human body, virus particles are identified by pattern recognition receptors (PRRs) either within or on the cell surface. When a receptor is activated, a signaling cascade is initiated, which results in the production and release of signaling molecules like interferons and cytokines.

Significance of astrocyte–neuron interactions in fine-tuning brain function

Humans learn to handle a variety of skilled movements throughout their lives, from driving a car to swinging a tennis racket. Neurons are not the only ones who implement this learning, but a new study from The Picower Institute for Learning and Memory at MIT shows that astrocytes play an important role as well.
