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.
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.
In diseases such as multiple sclerosis, cells of the immune system infiltrate the brain tissue, where they cause immense damage.
Understanding how neurons migrate to their proper place during brain development will offer insights into how malfunctions in the machinery cause epilepsy and mental retardationMEMPHIS, 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.
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.
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 â€˜reactive glial cellsâ€™ in the brains of mice and men originate from, and which cells they evolve into was hitherto unknown.

- A standing still or idling (of mills, factories, etc.).
