Researchers investigate the potential value of a new vaccine candidate for the influenza virus.

Many people develop Alzheimer's or other forms of dementia as they get older. However, others remain sharp well into old age, even if their brains show underlying signs of neurodegeneration.

A study by UT Southwestern researchers finds that changing the biochemistry of parts of brain cells abolished the formation of amyloid beta plaques in a mouse model of Alzheimer's disease.

Researchers around the world have tried many ways, and for many years, to generate neurons in the lab so they could study them better. Neurons-on-demand might also provide a therapeutic option for replacing neurons lost in neurodegenerative conditions, such as Parkinson's disease.

Scientists at the Centro Nacional de Investigaciones Cardiovasculares Carlos III and the Spanish Cardiovascular Research Network (CIBERCV), led by Dr Vicente Andrés, have generated the HGPSrev experimental mouse model.

A heart attack kills heart muscle cells, leading to a scar that weakens the heart, often leading to eventual heart failure. The lack of muscle repair is due to the very limited ability of mammalian heart muscle cells to proliferate, except for a brief period around birth.

Osteocalcin (OCN) is a multifunctional bone-derived hormone that modulates numerous physiological activities. OCN can cross the blood brain barrier (BBB) and thus play critical roles in neuronal and brain development.

Dementia- a condition involving the extreme loss of cognitive function- is caused by a variety of disorders, including Alzheimer's disease.

In response to gut inflammation, such as that caused by inflammatory bowel disease (IBD), the vascular barrier in the brain choroid plexus closes, locking down access to the brain, according to a new study.

Like DNA, RNA molecules contain information through unique combinations of four different nucleotides. However, through a molecular process called RNA editing, chemical changes can be made to adenosine nucleotides that convert them to a nucleotide called inosine by enzymes known as adenosine deaminases (ADARs).
