St. Jude Children's Research Hospital scientists report new details about mechanisms regulating a crucial step in brain development, offering insight into the origins of epilepsy, mental retardation and possibly brain tumor metastasis St. Jude Children's Research Hospital investigators have identified key components of a signaling pathway that controls the departure of neurons from the brain niche where they form and allows these cells to start migrating to their final destination. Defects in...

The generation of new nerve cells in the brain is regulated by a peptide known as C3a, which directly affects the stem cells' maturation into nerve cells and is also important for the migration of new nerve cells through the brain tissue, reveals new research from the Sahlgrenska Academy published in the journal Stem Cells. Although the research has been carried out using mice and cultured cells, it could lead to a new medicine for human beings, which could be given to patients who have had a...

Real-time observation sheds new light on multiple sclerosis In diseases such as multiple sclerosis, cells of the immune system infiltrate the brain tissue, where they cause immense damage. For many years, it was an enigma as to how these cells can escape from the bloodstream. This is no trivial feat, given that specialized blood vessels act as a barrier between the nervous system and the bloodstream. Until now, tissue sections provided the sole evidence that the immune cells really do manage...

Understanding how neurons migrate to their proper place during brain development will offer insights into how malfunctions in the machinery cause epilepsy and mental retardation MEMPHIS, Tenn., July 15 /PRNewswire-USNewswire/ -- The molecular machinery that helps brain cells migrate to their correct place in the developing brain has been identified by scientists at St. Jude Children's Research Hospital. The finding offers new insight into the forces that drive brain organization in...

A newly identified molecular pathway that directs stem cells to produce glial cells yields insights into the neurobiology of Down's syndrome and a number of central nervous system disorders characterized by too many glial cells, according to a recent study by researchers at the Salk Institute for Biological Studies.Their findings, to be published in the March 13 online edition of Cell Death and Differentiation, indicate that synaptojanin-1, a central component of the pathway, is essential to...

Most cells in the human brain are not nerve cells, but supporting cells (glial cells). They serve as a framework for nerve cells and play an important role in the wound reaction that occurs with injuries to the brain. However, what these "Ëœreactive glial cells' in the brains of mice and men originate from, and which cells they evolve into was hitherto unknown.Now, the study group of Prof. Dr. Magdalena Götz is able to show that after injury, these reactive glial cells in the...
