Researchers shed new light on the body's largest cell receptor

A giant toadstool that swallow up vitamins and nutrients. This is how the receptor, which e.g. absorbs B12 vitamin, looks. For the first time, researchers have an insight into a biology which has survived millions of years.

Researchers develop new method of analysis to map cellular locations of proteins

Researchers at Karolinska Institutet and SciLifeLab have developed a new method of analysis that maps the location of proteins in the cell. The information has been compiled in a database that is accessible to researchers around the world.

Fruit fly study sheds light on the evolution of metabolism

Diet choice of animal species is highly variable. Some are specialists feeding only on one food source, such as a sugar-rich fruit or protein-rich meat. Other species, like humans, are generalists that can feed on different kinds of food sources.

Senescent cells in the brain shown to cause obesity-related anxiety

Researchers have shown that obesity increases the level of semi-dormant senescent cells in the brain, which give rise to anxiety-like behaviors.

Researchers reveal cause of possible genetic problems in mitochondria

A group of researchers from the Andalusian Centre for Molecular Biology and Regenerative Medicine has revealed the importance of eliminating any excess of defective products that might have accumulated in the mitochondria, as its presence generates mitochondrial instability and information loss on the mitochondrial genome.

Hyperactive immune system implicated in aging brain disorders

In a study of fruit flies, NIH scientists suggested that the body's immune system may play a critical role in the damage caused by aging brain disorders. The results are based on experiments in which the researchers altered the activity of Cdk5, a gene that preclinical studies have suggested is important for early brain development and may be involved in neurodegenerative diseases, such as ALS, Alzheimer's and Parkinson's disease.

Study uncovers how tumors backfire on neoadjuvant chemotherapy

Some patients with breast cancer receive chemotherapy before the tumor is removed with surgery. This approach, called 'neoadjuvant' therapy, helps to reduce the size of the tumor to facilitate breast-conserving surgery, and can even eradicate the tumor, leaving few or no cancerous cells for the surgeon to remove.

Salk scientists show how brain cells filter information in groups

When we perceive the world around us, certain objects appear to be more noticeable than others, depending on what we do. For example, when we view a forest-covered mountain from a distance, the forest looks like a large green carpet. But as we get closer, we start noticing the individual trees, and the forest fades to the background.

New research could help restore youthful characteristics

If only we could keep our bodies young, healthy and energetic, even as we attain the wisdom of our years. New research at the Weizmann Institute of Science suggests this dream could be at least partly obtainable in the future.

New insights on cellular death mechanisms caused by the loss of neuronal cells and astrocytes

The blood circulation to neurons is affected due to Ischemic, hemorrhagic stroke and subarachnoid hemorrhage stimulation the activation of pathophysiological responses i.e. mitochondrial death pathways, protein misfolding, apoptosis, pyroptosis, necrosis, autophagy, mitophagy, ferritinophagy, excitotoxicity, free radicals release, and inflammation.

Sound can affect perception of touch in mice

Our eyes, ears and skin are responsible for different senses. Moreover, our brain assigns these senses to different regions: the visual cortex, auditory cortex and somatosensory cortex. However, it is clear that there are anatomical connections between these different cortices such that brain activation to one sense can influence brain activation to another

Research reviews role of protein tyrosine phosphatase in molecular biology

As the proteomics technology develops and human genomic analysis becomes easier to execute, molecules involved in the regulation of biochemical signaling pathways have become interesting subjects for researchers.

Multi-database electronic research finds link between gene polymorphisms with zinc status

Zinc is one of the essential components in the diet of all living organisms. It is the second most abundant biological trace element after iron.

Study finds how long-term memory encoded engram neurons are formed

While long-term memory is known to be encoded in specific neural cells, engram neurons, it has been unclear how these engram neurons are formed during training.

Study suggests dopamine release in the brain occurs twice per meal

We know a good meal can stimulate the release of the feel-good hormone dopamine, and now a study in humans from the Max Planck Institute for Metabolism Research in Germany suggests that dopamine release in the brain occurs at two different times: at the time the food is first ingested and another once the food reaches the stomach.

How physical activity decreases belly fat in humans

Some of you may have made a New Year's resolution to hit the gym to tackle that annoying belly fat. But have you ever wondered how physical activity produces this desired effect? A signaling molecule called interleukin-6 plays a critical role in this process, researchers report December 27 in the journal Cell Metabolism.

Study explains effects of aging on endothelial health and vascular regenerative capacity

The endothelium plays an important role in cardiovascular regulation, from blood flow to platelet aggregation, immune cell infiltration and demargination.

Kanazawa University researchers unravel link between inflammation and cancer

Severe inflammation in tissues is often associated with the occurrence of cancer. The mechanism linking both these conditions is not clearly understood. Furthermore, inflamed and cancerous tissues contain a heterogenous mix of damaged and protective cells.

Gently stroking babies could provide effective pain relief before medical procedures

Researchers found that gently stroking a baby seems to reduce activity in the infant brain associated with painful experiences. Their results, appearing December 17 in the journal Current Biology, suggest that lightly brushing an infant at a certain speed--of approximately 3 centimeters per second--could provide effective pain relief before clinically necessary medical procedures.
