One injection of gene therapy spreads through brain in animal study

By targeting a site in a mouse brain well connected to other areas, researchers successfully delivered a beneficial gene to the entire brain - after one injection of gene therapy.

Viewing dye-packed vesicles causes them to explode

It's a long-standing question: Can just the act of observing an experiment affect the results, According to a new study by Rockefeller University scientists, if the experiment uses a fluorescent dye called acridine orange, the answer is a resounding yes."

Process of necrosis redefined in landmark study

A new study led by investigators from the University of Pittsburgh School of Medicine demonstrates that the process of necrosis, long thought to be a chaotic, irreversible pathway to cell death, may actually be triggered as part of a regulated response to stress by a powerful protein, SRP-6, that can potentially halt necrosis in its path.

Mechanism for the in-vivo transport of siRNA

It all started with flowers: in the nineties of the last century Norwegian researchers discovered that additional copies of a particular gene in petunias inhibited its activity instead of reinforcing it as had been assumed.

Rochester receives $1.2 million to battle rare childhood disease

"For an orphan disease like Batten, which has such a clear-cut course of deterioration and no present cure, this grant is transformative both for these families and for us, as clinicians and researchers."

Scientists link cell's protein recycling systems

Many age-related neurological diseases are associated with defective proteins accumulating in nerve cells, suggesting that the cell's normal disposal mechanisms are not operating correctly.

Researchers discover how strokes trigger biochemical events that increase amyloid-beta production in the brain

Researchers from the MassGeneral Institute for Neurodegenerative Disorders (MGH-MIND) have discovered how the death of brain cells caused by a stroke or head injury may cause generation of amyloid-beta protein ? the key component of senile plaques seen in the brains of patients with Alzheimer's disease.

Strokes role in Alzheimer's disease

Researchers have discovered key details of how stroke or traumatic brain injury can trigger Alzheimer's disease (AD) by enhancing formation of brain-clogging amyloid plaques.

New hope for Krabbe disease sufferers

By all expectations, it shouldn't have worked as well as it did. A combination of bone marrow transplantation and gene therapy greatly lengthened the lives of laboratory mice doomed by a rapidly progressing, fatal neurodegenerative disorder also found in people.

Functionalized carbon nanotubes are non-cytotoxic and preserve the functionality of primary immune cells

Various types of carbon-based nanomaterials, such as buckyballs and nanotubes, have shown promise as drug delivery tools and imaging agents, but reports of toxicity associated with some of these materials have raised questions about their ultimate utility in clinical oncology.

Simple screening process opens door to treating rare metabolic diseases such as Tay-Sachs, Fabry and Gaucher syndromes

Rare metabolic diseases such as Tay-Sachs, Fabry and Gaucher syndromes are caused by enzyme deficiencies and typically have crippling, even fatal, consequences starting at very early ages.

Macrophages kill bacteria - but not always

Macrophages are effective weapons used by our immune system to absorb and digest pathogenic intruders. Some bacteria, however, can subvert this defence mechanism and even multiply within the macrophages.

Researchers successfully treat laboratory model of a lysosomal storage disease called GM1

Physicians might one day be able to treat a disease that destroys brain cells in children using genetically modified cells to transport a "drug" to the site of the dying neural cells (cells that transmit impulses).

Autophagy is also cell's second line of defense against invading pathogens such as strep

Cells give up their secrets slowly. Just when you think that all major cellular systems are understood, along comes a surprise. The latest is about autophagy, a major pathway for degrading and recycling within cells.

First use of technology called ubiquitin-mediated fluorescence complementation to study a cell-signaling mechanism called ubiquitination

Researchers at the University of Michigan Medical School and Howard Hughes Medical Institute have found a way to see proteins in cells that have been tagged by a molecular “sticky note” called ubiquitin.
