Cascade aggravates hereditary storage diseases

In rare, hereditary storage diseases such as Sandhoff's disease or Tay-Sachs syndrome, the metabolic waste from accumulating gangliosides cannot be properly disposed of in the nerve cells because important enzymes are missing.

Nanotubes enable movement of toxic protein linked to Huntington's disease

A toxic protein linked to Huntington's disease can move from neuron to neuron through a nanotube tunnel whose construction is initiated by a protein called Rhes, say scientists at Scripps Research.

Review highlights calcium handling mechanisms involved in reperfusion injury

Stroke and myocardial infarction (MI) are a significant cause of death and disability worldwide. However, over the past several decades because of advances in medicines (thrombolytic agents, antiplatelet drugs, beta blockers, and angiotensin converting enzyme inhibitors) and approaches to restore tissue perfusion (percutaneous coronary intervention and cardiopulmonary bypass), the mortality of MI has declined dramatically.

NanoBioCel group develops lipid vesicles that can genetic material efficiently and viably

In a piece of research conducted in collaboration, the NanoBioCel group of the UPV/EHU's Faculty of Pharmacy, and the University of Elche have designed some niosomes, which are lipid vesicles for use in gene therapies designed to treat diseases of the central nervous system.

UVA researchers make unexpected discovery about irreplaceable nerve cells

Meticulous new research from the University of Virginia School of Medicine has changed a well-accepted scientific belief about neurons, the vital nerve cells that allow us to experience the world and record those experiences as memories in our brains.

How a single mutation can devastate cellular function

A scientist has shown how a single mutation in a protein found in astrocytes reproduces fibrous globs that devastate cellular function.

Study: Atg2 tethers pre-autophagosomal membrane to endoplasmic reticulum during autophagosome formation

Postdoctoral Researcher Tetsuya Kotani, Associate Professor Hitoshi Nakatogawa, Honorary Professor Yoshinori Ohsumi and colleagues at Tokyo Institute of Technology have analyzed the Atg protein Atg2, whose function had been completely unknown, and have discovered that Atg2 tethers the pre-autophagosomal membrane to the endoplasmic reticulum during autophagosome formation.

Daily exercise facilitates elimination of toxic proteins from muscles

A study published in Scientific Reports by researchers at the University of São Paulo in Brazil, in partnership with colleagues in the United States and Norway, shows that the lack of muscle stimulus results in a buildup of inadequately processed proteins in muscle cells and consequently leads to muscle weakness or wasting.

Researchers discover materials which form new presynapses for release of transmitters

Synapses are the interfaces for information exchange between neurons. Teams of scientists working with Professor Dr. Volker Haucke, Director at the Leibniz-Forschungsinstitut für Molekulare Pharmakologie and Professor at the Freie Universitaet Berlin, and Professor Dr. Stephan Sigrist at the Freie Universität Berlin discovered the materials, which form new presynapses for the release of transmitters. The findings may help to design better nerve-regenerating therapies in the future.

Researchers develop new system for effective cancer diagnosis and treatment

A research group consisting of scientists from NUST MISIS, the Technical University of Munich, Helmholtz Zentrum München, the University of Duisburg-Essen, and the University of Oldenburg has developed a system that allows doctors to both improve the accuracy of diagnosing malignant cells and to provide additional opportunities for cancer treatment.

MSU researchers uncover the effects of aging on regenerative ability of kidneys

Autophagy is a process of destruction and processing of damaged cell components by the cells themselves. It is used by a cell to clean itself of excessive organelles and sometimes for self-execution. This adaptive mechanism supports a healthy phenotype on the cellular level.

OHSU researchers discover disease in monkeys that mimics childhood neurodegenerative disorder

OHSU scientists have discovered a naturally occurring disease in monkeys that mimics a deadly childhood neurodegenerative disorder in people - a finding that holds promise for developing new gene therapies to treat Batten disease.

Researchers discover new protein that controls level of inflammation-inducing molecule

One of the major therapeutic targets for inflammatory diseases is the inflammation-inducing molecule TNF. However, excess levels of TNF cause side effects and can lead to diseases.
