The degeneration of brain cells that occurs in Parkinson's disease may be caused by either externally provoked cell death or internally initiated suicide when the molecule that normally prevents these fatal alternatives is missing, according to studies in mouse models by investigators at St. Jude Children's Research Hospital.

- Replacing the cells lost in Parkinson disease
12-03-2007 · EurekAlert!
Parkinson disease is caused by the progressive degeneration of dopamine brain cells. Replacing these cells is considered a promising therapeutic strategy. Although DA cell-replacement therapy by transplantation of human fetal mesencephalic tissue has shown promise, limited tissue availability means other sources of these cells are needed. A recent study has described one new source for DA cells that provided marked benefit when transplanted into mice with a PD-like disease.

- A stepwise retreat: How immune cells catch pathogens
07-11-2007 · EurekAlert!
To protect us from disease our immune system employs macrophages, cells that roam our body in search of disease-causing bacteria. With the help of long tentacle-like protrusions, macrophages can catch suspicious particles, pull them towards their cell bodies, internalize and destroy them. Using a special microscopy technique, researchers from the European Molecular Biology Laboratory now for the first time tracked the dynamic behavior of these tentacles in three dimensions.

03-19-2007 · EurekAlert!
A research team headed by Academy Research Fellow Michael Courtney has identified a new molecular pathway in neurons. The pathway is a factor in the degeneration of brain cells, which in turn plays an important role in neurological conditions and diseases, such as Alzheimer's disease, epilepsy and stroke.

10-18-2006 · EurekAlert!
In a finding that contradicts current theories behind Parkinson's disease, neuroscientists at Duke University Medical Center have discovered in mice that critical nerve cells fire all at the same time and thus overwhelm the brain's ability to control the body's movements.

03-13-2007 · EurekAlert!
Uncontrolled neuronal death in the brain often gives rise to neurodegenerative illnesses like Parkinson or Alzheimer disease. Whether or not neurons have a long and healthy life is, apart from other factors, determined by the presence of neurotrophic factors. Scientists of the Max Planck Institute of Neurobiology have now provided unambiguous proof that the presence of the neurotrophic factor GDNF and its receptor Ret are essential for the survival of neurons in a specific brain region.
