Abstract
Spinal cord injury (SCI) is a systemic injury. The spinal damage provokes not only local responses but also a number of dysregulations in peripheral organs that, in turn, affect the spinal cord. Each human lesion is unique and thus biomaterial-based therapies should be individually tailored. Studies performed on human subjects and postmortem tissue samples are burdened by important limitations. Four categories of human SCI have been established based on the macroscopic/low magnification appearance of the injured cord: solid cord injuries, contusions/cavities, lacerations, and massive compressions. In addition, two different damages occur after SCI: the insult itself that leads to the primary damage and the subsequent cascade of pathological processes that further enlarge the lesion, defined as the secondary damage. Beside, there is increasing evidence that acute and chronic SCI are associated with a severe dysfunction of the immune system, which includes three main syndromic alterations: (i) systemic inflammation; (ii) immunodeficiency; and (iii) autoimmune reactions. SCI dysfunction is mainly due to the alteration in the communication between the immune and neuroendocrine systems. Intestinal dysbiosis has been found in SCI patients, accompanied by loss of the integrity of the intestinal barrier. This increased intestinal permeability may play a role in the observed increase in bacterial translocation and, through it, in the disturbances of the innate and adaptive immune responses found.
