Neuroanatomy and glial cells come in many types (see, for example, the nervous system section of the list of distinct cell types in the adult human body). Neurons are the information-processing cells of the nervous system: they sense our environment, communicate with each other via electrical signals and chemicals called neurotransmitters across synapses, and produce our memories, thoughts and movements. Glial cells maintain homeostasis, produce myelin, and provide support and protection for the brain's neurons. Some glial cells (astrocytes) can even propagate intercellular calcium waves over long distances in response to stimulation, and release gliotransmitters in response to changes in calcium
Glial scar animal). Further, a reduction in astrocytes and microglia, as well as a reduction in inflammation and angiogenesis, were observed. Interleukin-6 (IL-6) is thought to be a molecular mediator of glial scar formation. It has been shown to promote differentiation of neural stem cells into astrocytes. A monoclonal antibody, MR16-1, has been used to target and block the IL-6 receptors in rat spinal cord injury models. In a study by Okada "et al.", mice were intraperitoneally injected with a single dose of MR16-1 immediately after generating a spinal cord injury. Blockade of IL-6 receptors decreased the number of astrocytes present at
