We investigated the mechanisms that regulate the efficacy of agonists in the arginine-vasopressin (AVP)/oxytocin (OT) receptor system. In this paper, we present evidence that AVP, a full agonist of the vasopressin receptors, acts as a partial agonist on the oxytocin receptor. We also found that AVP becomes a full agonist when two aromatic residues of the(More)
Brain-derived neurotrophic factor (BDNF) is a neurotrophin that influences neuronal plasticity throughout life. Emergence from a vegetative state (VS) after a traumatic brain injury (TBI) implies that the brain undergoes plastic changes. A common polymorphism in the BDNF gene--BDNF Val66Met (referred to herein as BDNF(Met))--impairs cognitive function in(More)
The mechanisms involved in secondary brain injury after the acute phase of severe traumatic brain injury (TBI) are largely unknown. Ongoing axonal degeneration, consequent to the initial trauma, may lead to secondary brain injury. To test this hypothesis, we evaluated the cerebrospinal fluid (CSF) level of neurofilament light chain (NF-L), a proposed marker(More)
Traumatic brain injury (TBI) is a major risk factor for Alzheimer's disease. Recent studies suggest that amyloid-beta (Aβ) deposit can be detected several years after TBI. However, it is unknown whether post-TBI Aβ deposits arise from short-term changes in Aβ metabolism or reflect a long-term sequela. To answer this question, we evaluated the cerebrospinal(More)
