Abstract
Mild traumatic brain injury (TBI) is a major risk factor for post-traumatic stress disorder (PTSD), and both disorders share common symptoms and neurobiological defects. Relapse after successful treatment, known as long-term fear resurgence, is common in PTSD patients and a major therapeutic hurdle. We induced a mild focal TBI by controlled cortical impact (CCI) in male C57BL/6 J mice and used fear conditioning to assess PTSD-like behaviors and concomitant alterations in the fear circuitry. We found for the first time that mild TBI, and to a lesser extent sham (craniotomy), mice displayed a spontaneous resurgence of conditioned fear when tested for fear extinction memory recall, despite having effectively acquired and extinguished conditioned fear 6 weeks earlier in the same context. Other characteristic symptoms of PTSD are risk-taking behaviors and cognitive deficits. CCI mice displayed risk-taking behaviors, behavioral inflexibility and reductions in processing speed compared to naïve mice. In conjunction with these changes there were alterations in amygdala morphology 3 months post-trauma, and decreased myelin basic protein density at the primary lesion site and in distant secondary sites such as the hippocampus, thalamus, and amygdala, compared to sham mice. Furthermore, activity-dependent brain-derived neurotrophic factor (BDNF) transcripts were decreased in the prefrontal cortex, a key region for fear extinction consolidation, following fear extinction training in both TBI and, to a lesser extent, sham mice. This study shows for the first time that a mild brain injury can generate a spontaneous resurgence of conditioned fear associated with defective BDNF signalling in the prefrontal cortex, PTSD-like behaviors, and have enduring effects on the brain.

Abstract
The aim of this study was to find a plasma biomarker, in relation with nitric oxide (NO), as a sign of brain damage severity following traumatic brain injury (TBI). We first investigated the post-traumatic evolution of the plasma concentrations of NO via the level of NO end-products metabolites (nitrite plus nitrate, NO(x)), that of l-arginine (Arg) and amino acids involved in its metabolism as well as the time course of neurological score in a rat model of lateral fluid percussion brain injury. First, the level of NO(x) was increased in plasma at 24 and 48 h post-TBI with a marked increase at 72 h. In contrast, this elevation was neither accompanied by a modification of plasma concentrations of Arg, nor of amino acids involved in NO and Arg metabolism, l-ornithine (Orn), l-glutamate (Glu), and l-glutamine (Gln). Second, TBI induced a fall of plasma l-proline (Pro) concentrations. The time course of post-TBI neurological deficit showed also a decrease of neurological score at 24, 48, and 72 h. Furthermore, there is a weak negative correlation between the neurological score and the plasma level of NO(x) (r=-0.305; P<0.05), while a marked positive correlation has been found between the neurological score and the plasma level of Pro (r=0.563; P<0.001). In conclusion, the plasma concentrations of Pro could be a promising marker of post-traumatic neurological deficit.
