Today, stem cell transplantation is a hot topic in scientific circles as a novel therapeutic approach to repair the structure and function of central nervous system. The safe and neuroprotective effects of cell therapy in models and traumatic brain injury patients were evaluated in many experimental and clinical studies in recent decade and somewhat promising results were provided to the scient...

The accumulation of myelin debris may be a major contributor to the inflammatory response after diffuse axonal injury. In this study, we examined the accumulation and clearance of myelin debris in a rat model of diffuse axonal injury. Oil Red O staining was performed on sections from the cerebral cortex, hippocampus and brain stem to identify the myelin debris. Seven days after diffuse axonal i...

blood brain barrier (bbb) is a specialized non fenestrate barrier that formation by the endothelial cells and controls the transportation of the cells and molecules in to the brain. reducing in function of bbb is one of disruptions in neurological diseases like multiple sclerosis. endothelial progenitor cell (epc) help to the bbb to control the diapedesis of inflammatory cells & molecules in to...

There is an increase in the numbers of neural precursors in the SVZ (subventricular zone) after moderate ischaemic injuries, but the extent of stem cell expansion and the resultant cell regeneration is modest. Therefore our studies have focused on understanding the signals that regulate these processes towards achieving a more robust amplification of the stem/progenitor cell pool. The goal of t...

The potential use of human embryonic stem cells for the treatment of neurological disease and injury is discussed from the perspectives of two common disease scenarios. Spinal cord injury and diseases such as multiple sclerosis that affect specific cell types in the spinal cord represent a substantial proportion of all neuropathologies and are among the most heavily targeted by efforts to estab...

penetrating neck trauma is an important area of trauma care that has undergone evolution in the recent past. a remarkable number of changes have occurred in the treatment paradigm as new technologies have developed and as surgeons have explored the outcomes from different treatment protocols. therapy has evolved from no treatment (before effective anesthesia and instrumentation), to non operati...

Microglia is one of the first innate immune components. These cells account about 5 to 10% of the entire adult brain cells and are activated by trauma. Complex-mediated inflammatory responses occur through cellular and molecular events during and after the traumatic brain injury (TBI). In-lesion area astrocytes, microglia, and damaged neurons begin to secrete cytokines and chemokines. Microglia...
