New Discovery Sheds Light on How Monoamines Regulate Brain Rhythms

A collaborative effort between Mount Sinai and Memorial Sloan Kettering Cancer Center has shed valuable light on how monoamine neurotransmitters such as serotonin, dopamine, and now histamine help regulate brain physiology and behavior through chemical bonding of these monoamines to histone proteins, the core DNA-packaging proteins of our cells.

Identifying PRIMER Cells and their Role in Defense Signaling

A diverse population of immune cells that move from one organ to another and react to anything from cuts to colds to cancer is how human bodies protect themselves. However, this luxury is not available to plants.

New Study Reveals DNA’s Role in Stabilizing Cellular Structures

In a discovery that could redefine how we understand cellular resilience and adaptability, scientists at Scripps Research have unlocked the secret interactions between a primordial inorganic polymer of phosphate known as polyphosphate (polyP), and two basic building blocks of life: DNA and the element magnesium.

Plant Research Reveals Unexpected Function for Key Cellular Protein

A cell protein previously believed only to provide a scaffolding for DNA has also been shown to directly influence DNA transcription into RNA – the first step of the process by which an organism's genetic code expresses itself. The fundamental breakthrough was discovered in apple cells but is relevant to all living organisms made of nucleus-containing cells, including humans.

Researchers Create 3D Atlas of Brain-Spinal Cord Connections

Signals relayed to motor neurons from the brain enable muscle movement, but these signals typically pass through spinal interneurons before they reach their destination. How the brain and this highly diverse group of "switchboard operator" cells are connected is poorly understood.

ALS Stem Cell Model Reveals Increased Susceptibility to Cell Death

Amyotrophic lateral sclerosis (ALS) is a fast-progressing neurodegenerative disease with an average survival time of three years. In ALS, certain types of neurons called motor neurons that are required for muscle contractions die off, leading to progressive paralysis affecting most muscles of the body. The molecular causes of ALS are poorly understood, and effective treatments are missing.

Chaperone Proteins Unveil Their Role in Neurotransmission

A team of researchers from the University of Massachusetts Amherst is the first to show how proteins called "chaperones" are vital in ensuring that neurons can transmit signals to one another. When this neurotransmission breaks down, devastating diseases such as Alzheimer's and Parkinson's along with many others, can occur.
