Abstract:
:Evidence and inferences from clinical research, clinical observation, and literature review support an etiologic paradigm for the pathophysiology of spinal cord injury (SCI). According to this paradigm, changes in immunoregulation and in the activation of cytokines or intercellular adhesion molecules (ICAMs) contribute to many of the comorbidities, metabolic changes, and pathophysiologic sequelae observed after traumatic SCI. Cytokines and ICAMs are endogenously secreted molecules that serve as intercellular signals and immunoregulators. They modulate the activity of cells and influence the organization and function of tissues or organs. These intercellular signals are posited as molecular links between the damaged, decentralized nervous system of SCI and the acquired autonomic failure, neuroendocrine-immunoregulatory dysfunction, diminished central nervous system (CNS) regenerative capacity, and broad spectrum of pathology, organ failure, and generalized impairment of homeostasis caused by trauma to the spinal cord. These highly bioactive molecules may also mediate or facilitate the intralesional CNS axonal damage and peripheral neurologic deficits sustained at time of acute CNS injury. Ultimately, it should be possible to develop treatments that will block or modulate the local and systemic expression of cytokine or ICAM bioactivity. Such treatments might aid victims of SCI by diminishing overall morbidity or mortality, helping restore sensorimotor function and homeostasis, and enhancing longevity and quality of life.
