Summary: Traumatic brain injury is a leading cause of death and disability worldwide. Currently, there are no targeted therapies for preventing or limiting the secondary damage caused by traumatic brain injury. However, nerve growth factor shows promise in preventing or limiting this secondary damage, especially when delivered intranasally. This review examines the dysfunctional mechanisms of traumatic brain injury that may benefit from nerve growth factor treatment and discusses the experimental evidence and effects of intranasal nerve growth factor treatment on traumatic brain injury outcomes.

Summary: Neurotrophins play crucial roles in neural development, survival, and plasticity, and are key regulators of neuroinflammation, apoptosis, memory capacity, and neurite regeneration following traumatic brain injury. The expression of neurotrophins post-TBI is influenced by injury severity, genetic polymorphism, and timing of trauma. Emerging research is exploring the therapeutic potential of neurotrophins in managing TBI.

Summary: This study investigates the formation of the epichaperome in traumatic brain injury (TBI) and suggests that this mechanism may contribute to protein misfolding, degradation, aggregation, and transport. Further understanding of this pathological mechanism can provide insights into the connection between TBI and increased risk of neurodegenerative diseases, as well as potential therapeutic targets.

Summary: Hippocampal dysfunction post-TBI is influenced by sex-related neuroprotective hormones, with females showing superior outcomes to males. CYP1B1 expression in response to pTBI differs between sexes, with females displaying a more urgent but brief regulatory response compared to males. Sex-dependent differences in CYP1B1 activity may affect inflammation and neuroprotection in pTBI.

Summary: The study demonstrates the therapeutic effect of using injectable hyaluronic acid hydrogel encapsulated with bone mesenchymal stem cells and nerve growth factors for traumatic brain injury. The hydrogel loaded with BMSC and NGF improved neurological function recovery by promoting neurotrophic factors release and neuroinflammation regulation, accelerating the repair process.

Summary: Severe traumatic brain injury in pediatric patients is a critical condition with limited treatment options. A study suggests that intranasal administration of hr-NGF may improve neurological function and clinical outcomes in these patients.

Summary: Traumatic brain injury (TBI) leads to neuroinflammation, reactive astrogliosis, and cognitive and motor damage. Intranasal delivery of nerve growth factor (NGF) can limit and improve the outcomes of secondary damage. Experimental results showed that NGF administration reduced motor dysfunction and neuroinflammation.

Summary: Traumatic brain injury (TBI) is brain damage caused by external forces. Mild TBI (mTBI) is the most common type of TBI and repeated mTBI increases the risk of neurodegenerative diseases. This study evaluated mitochondrial calcium dynamics in an mTBI mouse model using isolated hippocampal mitochondria. The findings showed that mTBI results in decreased mitochondrial membrane potential, increased basal matrix calcium levels, and increased NCLX protein levels.

Summary: We found that a distinct ferroptotic signature was detected in the injured hippocampus at the early stage of traumatic brain injury (TBI). Elevated levels of arachidonic acid (AA), ACLS4, and ALXO15, and deficiency of GPX4 were observed in the hippocampus after TBI, creating a pro-ferroptosis environment. Gpx4 overexpression alleviated TBI-induced cognitive deficits and reversed hippocampal ferroptosis and synaptic damage.

Summary: The study found that melatonin only enhanced cognition when administered during the early pathological stages of TBI, with no effect in the late (chronic) stages. Furthermore, an increase in neuronal activity and inhibition of astrocyte reactivation were observed in cognition-related brain regions such as the medial prefrontal cortex and hippocampus.

Summary: This study aimed to analyze the effect and mechanism of Wnt5a-loaded fibrin hydrogel on a 10-mm rat sciatic nerve defect. Results showed that Wnt5a could promote Schwann cell proliferation and the expression of various neurotrophic factors, and the Wnt5a/Fn group outperformed the control groups in terms of nerve regeneration and functional recovery 12 weeks after the operation. The Wnt5a/Fn nerve conduit may promote peripheral nerve defect regeneration by facilitating multiple neurotrophin secretion, combining vascularization and neurotrophic growth cues.

Summary: Exo70, a subunit of the exocyst complex, is involved in cellular membrane addition and polarized exocytosis. After traumatic brain injury, Exo70 is redistributed from microsomes to the synaptic compartment, where it interacts with GluN2B. This redistribution may play a compensatory role in maintaining GluN2B on synapses, potentially reducing the detrimental effects associated with TBI.

Summary: This study evaluated the effects of bevacizumab on ApoE(-/-) mice undergoing TBI, and found that bevacizumab improved motor deficits, reduced VEGF levels and brain edema, preserved BBB integrity, and mitigated neuroinflammation induced by TBI. Additionally, it was observed for the first time that bevacizumab prevented the acceleration of atherosclerosis.
