Protein plays important roles in intracellular membrane trafficking in the brain

Our bodies couldn’t operate without the central nervous system - a complex network that coordinates our actions, reflexes, and sensations. Each neuron in your brain has one long cable that snakes away from the main part of the cell.

Researchers unlock mystery of immunosuppressive drug's biosynthesis

Mycophenolic acid (MPA), discovered in 1893, was the first natural antibiotic to be isolated and crystallized in human history.

Researchers demonstrate how manganese produces parkinsonian syndrome

Using X-ray fluorescence at synchrotrons DESY and ESRF, researchers in the Centre d'Etudes Nucléaires de Bordeaux Gradignan have demonstrated the consequences of a mutation responsible for a hereditary parkinsonian syndrome: accumulated manganese in the cells appears to disturb protein transport.

Researchers shed new light on how to combat Shiga and ricin toxins

Min Dong, PhD, and his lab are world experts in toxins and how to combat them. They've figured out how Clostridium difficile's most potent toxin gets into cells and zeroed in on the first new botulinum toxin identified since 1969.

One type of Chlamydia protein manipulates human cells in two different ways

When Chlamydia trachomatis, the bacterium that causes one of the most common sexually transmitted infections worldwide, infects a human cell, it hijacks parts of the host to build protective layers around itself.

New discovery in cell biology can have implications for research into autoimmune diseases

Research carried out by the University has discovered the first data on an organelle that is really important in human cells in an ancient organism distantly related to humans.

Golgi stress signaling pathway found in cells with Huntington’s disease

Working with cells grown in the lab, Johns Hopkins researchers have identified a biochemical pathway that allows a structure within cells, called the Golgi apparatus, to combat stress caused by free radicals and oxidants.

Excessive copper in diabetes impedes ability to make new blood vessels

It's a metal we worry thieves will steal from our air conditioners or power lines, but inside our bodies too much copper can result in a much larger loss.

Researchers explore new method of destroying tumor cells

Researchers from Lomonosov MSU Faculty of Biology have studied the stages of entosis, a process of cell death when one cell invades the other and gets digested inside of it. Entosis could become a new method of destroying cancer cells.

NTNU researchers reveal how HCV converts innocent cells into virus factories

The Hepatitis C (HCV) virus is a sly enemy to have in one's body. Not only does it manage to make itself invisible to the immune system by breaking down communication between the immune cells, it also builds secret virus "factories" that quickly go into mass production.

RUB researchers identify new rare muscle disorder

A new rare muscle disorder has been identified by researchers at Ruhr-Universität Bochum. This hereditary disease is caused by a defect in the BICD2 gene that manifests itself in altered cellular transport processes in skeletal muscle cells.

Scientists managed to produce large quantities of promising natural substance

Once they can synthesise molecules of active natural substances, scientists will be able to harness nature’s medicine cabinet for the drugs of the future.

Loss of Golgi function may contribute to pathology of neurodegenerative diseases

Disabling a part of brain cells that acts as a tap to regulate the flow of proteins has been shown to cause neurodegeneration, a new study from The University of Manchester has found.

Scientists identify ‘cellular post office’ that could be key to preventing spread of lung cancer

Scientists at the Universities of York and Texas have found that a component of cancer cells, which acts like a 'cellular post office', could be the key to preventing the spread of lung cancer to other parts of the body.

Research shows cellular component may play vital role in how lung cancer spreads

A cellular component known as the Golgi apparatus may play a role in how lung cancer metastasizes, according to researchers at The University of Texas MD Anderson Cancer Center whose findings were reported in the Nov. 21 online issue of the Journal of Clinical Investigation.

Scientists identify mutation responsible for new, rare genetic disorder

An international team of researchers has discovered the mutation responsible for a rare, newly identified genetic disorder that causes craniofacial abnormalities and developmental delays.

ULK1, ULK2 enzymes play key role in maintaining cellular homeostasis

Researchers at St. Jude Children's Research Hospital have uncovered how two enzymes, ULK1 and ULK2, which are best known for their role in the degradation and recycling of proteins, control the trafficking of specific proteins.

Familiar gene manages transport of proteins around the cell

How do cells avoid growing topsy-turvy? Growing so your top, front, bottom and back all wind up on the correct side requires a good sense of direction at the cellular level. A Hiroshima University research group has identified a familiar gene with an unexpected role in directing proteins around the cell.

Lack of ARHGAP33 molecule causes neuropsychiatric disorders-related abnormal higher brain functions

A research group led by Osaka University and the University of Tokyo found that the intracellular protein trafficking is important for higher brain functions such as learning and memory. The research group showed that a molecule, ARHGAP33 regulates synaptic functions and behaviors via intracellular protein trafficking and that the lack of ARHGAP33 causes neuropsychiatric disorder-related impaired higher brain functions.

Study suggests Golgi as potential drug target for Alzheimer's treatment

Alzheimer's disease (AD) progresses inside the brain in a rising storm of cellular chaos as deposits of the toxic protein, amyloid-beta (Aβ), overwhelm neurons. An apparent side effect of accumulating Aβ in neurons is the fragmentation of the Golgi apparatus, the part of the cell involved in packaging and sorting protein cargo including the precursor of Aβ. But is the destruction the Golgi a kind of collateral damage from the Aβ storm or is the loss of Golgi function itself part of the driving force behind Alzheimer's? This was the question for Yanzhuang Wang, Gunjan Joshi, and colleagues at the University of Michigan, Ann Arbor, as they set out to uncover the mechanism damaging the Golgi, using a transgenic mouse and tissue culture models of AD to look at what was going on.
