Summary: This article discusses the therapeutic effects and possible mechanisms of hypothermia in patients with traumatic spinal cord injury (SCI). Early hypothermia has neuroprotective effects mainly during the first- and second-month post-SCI, but its beneficial effects gradually diminish over time. The article also mentions the potential complications and side effects of hypothermia.

Summary: Blood-spinal cord barrier (BSCB) disruption is a crucial event in spinal cord injury (SCI), allowing harmful substances to enter neural tissue and exacerbate secondary damage. The mechanisms of BSCB disruption in the acute phase of SCI remain unclear, leading to a lack of effective clinical treatment strategies.

Summary: Secondary spinal cord injury is caused by an irreversible inflammatory response cascade, and the immune system plays a crucial role in mediating inflammation. Investigating the mechanisms and functions of peripheral immune cells at the site of injury is significant for identifying clinical therapeutic targets.

Summary: High mobility group box 1 (HMGB1) functions both as a nonhistone nucleoprotein and an extracellular inflammatory cytokine. It is mainly located in the nucleus in the resting state and regulates key nuclear activities. After spinal cord injury, HMGB1 is expressed by neurons, microglia, and ependymal cells and released into the extracellular matrix and blood circulation, contributing to the pathophysiological process of spinal cord injury. HMGB1 can regulate microglia activation, exacerbate inflammation, and result in neuronal death. However, it has also been shown to benefit neuron survival, regeneration, and motor function recovery. This article reviews the timing of HMGB1 secretion and translocation, release mechanisms, and its role in spinal cord injury, and identifies challenges to be addressed.

Summary: Astroglial cells have a unique reaction during spinal cord damage, and there is a need for treatment targeting activated astrocytes to ensure some preservative effect during progressive damage. Functionalized nanogel-based nanovectors have shown selectivity towards astrocytes and limited uptake by macrophages, with potential therapeutic efficacy.

Summary: In this study, a functional hybrid gelatin and hyaluronic acid hydrogel (F-G/H) modified with cationic polymers and anti-inflammatory cytokines was developed to regulate the immune microenvironment after aSCT implantation. The hydrogel exhibited DAMP scavenging capacity, sustained release of anti-inflammatory cytokines, and reduced lymphocyte accumulation, thereby enhancing the survival and function of aSCTs. When combined with systemic immunosuppressive drug treatment, a significant improvement in locomotor functions of SCI rats was observed after aSCTs and F-G/H transplantation.

Summary: Cervical spondylotic myelopathy is a common cause of non-traumatic spinal cord injury. The main pathological changes involve compression and damage to the microvascular network, leading to ischemia and inflammation. Vascular regeneration and remodeling play a crucial role in neural repair.

Summary: This review summarizes the role of necroptosis in central nervous system trauma and its therapeutic implications, providing important suggestions for researchers conducting in-depth research. The study focuses on the necroptosis signaling pathway, execution, temporal patterns of RIPKs in CNS trauma, association of miRNAs with necroptosis, and different types of CNS trauma cell death. It also highlights potential agents for curtailing necroptosis-related cell death in CNS trauma.

Summary: After hypothermia treatment following acute SCI, more than 50% of patients showed improvement in neurological function. The proportion of cases showing neurological improvement was higher in the systemic hypothermia group compared to the local hypothermia group, although the difference was not statistically significant. There was no statistically significant difference in the proportion of cases with neurological improvement between cervical spine and thoracic spine injury groups.

Summary: The present study aimed to investigate the pro-angiogenic potential of OECs activated by CCM and LPS and the underlying mechanisms. The activated OECs were found to effectively promote proliferation, migration, and vessel-like structure formation of vascular endothelial cells. Several pro-angiogenic growth factors were significantly elevated in the conditioned medium (CM), and the PI3K/Akt signaling pathway was involved in these pro-angiogenic events. Transplantation of activated OECs improved angiogenesis and the microenvironment in the injured spinal cord.

Summary: Spinal cord injury (SCI) often leads to irreversible damage to neurons and glial cells, causing inflammation, ischemia, and cell death. Pyroptosis, a new form of regulated cell death, plays a vital role in SCI development. This review examines the evidence for pyroptosis in SCI, focusing on different cell types and their crosstalk. Additionally, the interaction between pyroptosis and other forms of cell death in SCI is discussed. The therapeutic strategies for inhibiting pyroptosis are summarized, providing novel insights for improving SCI outcomes.

Summary: Spinal cord injury is a devastating disease causing loss of sensory and motor functions, with a pathological process involving mechanical primary injury and secondary injury. Macrophages play a crucial role in the pathology of SCI, and can be divided into different types. Hematogenous macrophages may have various roles in SCI but their specific function remains controversial.

Summary: Spinal cord injury is a severe damage to the central nervous system, often leading to the loss of spinal cord structure and function. Researchers have developed a new hydrogel material with mechanical and electrical properties similar to the spinal cord, which can be used for spinal cord regeneration. By introducing glutathione and MMP-responsive proteins into the hydrogel, biomolecules can be released in response to the microenvironment of spinal cord injury, promoting axon regeneration and angiogenesis, and improving motor function recovery.

Summary: TG2 is a multifunctional enzyme involved in the pathogenesis of EAE and MS. It is found to be induced in neurons following EAE, particularly around perivascular lesion sites, and co-localizes with proteins related to apoptosis and ERK1/2 signaling. Additionally, TG2 is also expressed in vascular cells and relates to the upregulation of VEGF. Its cell autonomous functions during disease progression remain to be elucidated.
