Spinal cord injury (SCI) is considered an incurable condition, having a heterogenous recovery and uncertain prognosis. Therefore, a reliable prediction of the improvement in the acute phase could benefit patients. Physicians are unanimous in insisting that at the initial damage of the spinal cord (SC), the patient should be carefully evaluated in order to help selecting an appropriate neuroprotective treatment. However, currently, neurologic impairment after SCI is measured and classified by functional examination. The identification of prognostic biomarkers of SCI would help to designate SC injured patients and correlate to diagnosis and correct treatment. Some proteins have already been identified as good potential biomarkers of central nervous system injury, both in cerebrospinal fluid (CSF) and blood serum. However, the problem for using them as biomarkers is the way they should be collected, as acquiring CSF through a lumbar puncture is significantly invasive. Remarkably, microRNAs (miRNAs) have emerged as interesting biomarker candidates because of their stability in biological fluids and their tissue specificity. Several miRNAs have been identified to have their expressions altered in SCI in many animal models, making them promising candidates as biomarkers after SCI. Moreover, there are yet no effective therapies for SCI. It is already known that altered lysophospholipids (LPs) signaling are involved in the biology of disorders, such as inflammation. Reports have demonstrated that LPs when locally distributed can regulate SCI repair and key secondary injury processes such as apoptosis and inflammation, and so could become in the future new therapeutic approaches for treating SCI.
