At the site of injury, nerves release a protein called CXCL12 which attracts growing nerve fibers and keeps them trapped in place. This prevents the nerve fibers from growing in the correct direction to bridge the injury site.
Spinal cord injuries cause stem cells in the bone marrow to rapidly divide. Following the cell division, the stem cells become trapped in the bone marrow.
Researchers detail the use of a drug that may help block the way glioblastoma brain cancer cells respond to fluid flow. The finding could lead to stopping glioblastoma from spreading.
Researchers analyze the atomic structure of two types of human serotonin receptors. Their findings could explain why some drugs, which interact with these receptors, occasionally have harmful effects.
