Most spinal cord injuries have an almost immediate and devastating effect on the person’s motor control. These severe impairments result from the interrupted communication between the brain and spinal cord, which deprives the spinal cord below the injury of instructions from the higher-level executive functions in the body. Without the essential sources of direction and excitement from the brain, the parts coordinated below the injury on the spinal cord face severe motor deficits – often complete or partial paralysis.

The Nobel Prize in Medicine and Physiology for 2018 was awarded to Dr. James P. Allison and Dr. Tasuku Honjo for making breakthrough discoveries on strategies for treating cancer by preventing the “ignorance” of tumors by the immune system. Developing cancer cells are normally detected by surveying white blood cells, or T-lymphocytes, that recognize the tumor progenitors as abnormal and target the abnormal cells for destruction. However, as a tumor develops, the cancer cells of the tumor begin to send inhibitory signals to immune cells, causing them to “ignore” the growing tumor until it is virtually invisible to the immune system.
