    摘要: Collapsin response mediator proteins (CRMPs) decreased in tissue and increased in biological fluids after neural injury from traumatic brain injury (TBI). Significant decreases of CRMP1, CRMP2, CRMP4 and CRMP5 were accompanied by the appearance of distinct 58 kDa (CRMP-2) or 55 kDa (CRMP-4) breakdown products from proteolytic cleavage by calpain. Synaptotagmin breakdown products were also associated with TBI and could be detected along with intact protein in human cerebral spinal fluid (CSF). Both biomarkers were detected in human biofluid and related to recovery from traumatic brain injury.
