Intranasal delivery of small extracellular vesicles from specific subpopulation of mesenchymal stem cells mitigates traumatic spinal cord injury. J Control Release 2024; 369:335-350. [PMID: 38519036 DOI: 10.1016/j.jconrel.2024.03.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Revised: 03/14/2024] [Accepted: 03/19/2024] [Indexed: 03/24/2024]
Abstract
Vascular injury following spinal cord injury (SCI) can significantly exacerbate secondary SCI and result in neurological dysfunction. Strategies targeting angiogenesis have demonstrated potential in enhancing functional recovery post-SCI. In the context of angiogenesis, the CD146+ and CD271+ subpopulations of mesenchymal stem cells (MSCs) have been recognized for their angiogenic capabilities in tissue repair. Small extracellular vesicles (sEVs) derived from MSCs are nanoscale vesicles containing rich bioactive components that play a crucial role in tissue regeneration. However, the precise role of sEVs derived from CD146+CD271+ UCMSCs (CD146+CD271+ UCMSC-sEVs) in SCI remain unclear. In this study, CD146+CD271+ UCMSC-sEVs were non-invasively administered via intranasal delivery, demonstrating a significant capacity to stimulate angiogenesis and improve functional recovery in mice following SCI. Furthermore, in vitro assessments revealed the effective enhancement of migration and tube formation capabilities of the murine brain microvascular endothelial cell line (bEnd.3) by CD146+CD271+UCMSC-sEVs. MicroRNA array analysis confirmed significant enrichment of multiple microRNAs within CD146+CD271+ UCMSC-sEVs. Subsequent in vivo and in vitro experiments demonstrated that CD146+CD271+ UCMSC-sEVs promote enhanced angiogenesis and improved functional recovery mediated by miR-27a-3p. Further mechanistic studies revealed that miR-27a-3p sourced from CD146+CD271+ UCMSC-sEVs enhances migration and tube formation of bEnd.3 cells in vitro by suppressing the expression of Delta Like Canonical Notch Ligand 4 (DLL4), thereby promoting angiogenesis in vivo. Collectively, our results demonstrate that a crucial role of CD146+CD271+ UCMSC-sEVs in inhibiting DLL4 through the transfer of miR-27a-3p, which leads to the promotion of angiogenesis and improved functional recovery after SCI.

Abstract
Background Hip fracture is commonly in the elderly as a consequence of osteoporsis. Currently, China is entering an aging society and there is a lack of studies about the epidemiology and health burden of hip fracturs there. Methods We used data from the Global Burden of Disease study 2019 (GBD 2019) to estimate the incidence, prevalence and disease burden of hip fractures in China and the temporal trends from 1990 to 2019. These estimates were produced by DisMod-MR 2.1, a Bayesian meta-regression tool. Estimated annual percentage change (EAPC) was used to represent the temporal trends. Results In 2019, there was estimated to be 2.0 million incident and 2.6 million prevalent hip fracture cases in China. The age standardized incidence and prevalence rate were estimated to be 117.8 (95 % UI, 83.8 to 161.6) per 100,000 and 139.8 (95 % UI, 125.7 to 154.7) per 100,000, respectively. From 1990 to 2019, the incidence (EAPC, 1.06; 95 % CI, 0.6 to 1.52) and prevalence (EAPC, 1.41; 95 % CI, 1.02 to 1.8) rates have increased, while the age standardized DALY decreased (95 %CI, -1.8; 95 % CI, -2.3 to -1.2). The incidence and DALY rates of hip fractures increased with age, and female people have higher incidence rate and disease burden. Falls were the leading cause for hip fractures, followed by road injuries. Conclusion Due to population growth and ageing, the challenges from hip fractures are expected to increase in the future, and related measures are in need to reduce the related health and economic burden.

Abstract
Mitochondria are crucial in sustaining and orchestrating cellular functions. Capitalizing on this, we explored mitochondrial transplantation as an innovative therapeutic strategy for acute spinal cord injury (SCI). In our study, we developed an engineered mitochondrial compound tailored to target macrophages within the SCI region. Sourced from IL-10-induced Mertkhi bone marrow-derived macrophages, we conjugated a peptide sequence, cations-cysteine-alanine-glutamine-lysine (CAQK), with the mitochondria, optimizing its targeting affinity for the injury site. Our data demonstrated that these compounds significantly enhanced macrophage phagocytosis of myelin debris, curtailed lipid buildup, ameliorated mitochondrial dysfunction, and attenuated pro-inflammatory profiles in macrophages, both in vitro and in vivo. The intravenously delivered mitochondrial compounds targeted the SCI epicenter, with macrophages being the primary recipients. Critically, they promoted tissue regeneration and bolstered functional recovery in SCI mice. This study heralds a transformative approach to mitochondrial transplantation in SCI, spotlighting the modulation of macrophage activity, phagocytosis, and phenotype.

Abstract
Elezanumab is a fully human monoclonal antibody, which is directed against repulsive guidance molecule A. The safety, tolerability, pharmacokinetics (PK), and immunogenicity of elezanumab were assessed in 2 Phase 1 clinical studies. The objective of this study was to assess the PK, safety, tolerability, and immunogenicity following intravenous infusion of elezanumab in healthy adult Japanese, Han Chinese, and Caucasian participants as well as Western participants from the single-ascending-dose study. Elezanumab exposures were approximately 20% higher in Japanese and Han Chinese participants compared to White participants without controlling for body weight. After statistically controlling for body weight by including it as a covariate, the PK of elezanumab in White participants were comparable to those in Japanese and Han Chinese participants. The clinical implications of these exposure differences are yet to be determined. All adverse events were assessed by the investigator as having no reasonable possibility of being related to the study drugs and were mild in severity. No positive immunogenicity effect was observed that impacted elezanumab exposure or safety.

Abstract
Spinal cord injuries are incredibly disabling and can have fatal consequences. At present, there is a lack of available information regarding the epidemiological characteristics of patients who have experienced spinal cord injury (SCI) in China. This retrospective hospital-based study was conducted in the Rehabilitation department of Wuhan's Tongji Hospital between 2016 and 2022. A total of 649 individuals diagnosed with SCI (both traumatic and non-traumatic) were admitted during this period. Data regarding various epidemiological features were gathered, including sex, age, etiology, occupation, neurological level of injury, the American Spinal Injury Association Impairment Scale at the time of admission, and information on any accompanying injuries. Out of the 649 cases of SCI, there were 539 cases of traumatic SCI and 110 cases of non-traumatic SCI. The mean age at the time of injury was 45.6 ± 14.8 years. The ratio of male to female patients was higher in traumatic SCI at 2.82:1compared to non-traumatic SCI at 1.68:1. Traffic accidents were the most common cause of TSCI, accounting for (n = 207/539; 38.40%) of cases. On the other hand, neoplasm was the most common cause of NTSCI, accounting for (n = 38/110; 34.54%) of cases. The findings indicated a higher proportion of males, with traffic accidents being the main cause of injury among TSCI patients. It is crucial to prioritize the risk of falling among older adults and allocate more attention to this issue. These results emphasize the need for tailored preventive strategies that consider the unique characteristics of different types of SCI patients.

Abstract
BACKGROUND Spinal cord injury is a frequent debilitating neurologic condition with increasing prevalence and related morbidity over the last decades. The neutrophil-to-lymphocyte ratio is a promising biomarker for determining different medical conditions' disease course and outcome such as traumatic brain injury (TBI). This study aimed to investigate the predictive value of neutrophil to lymphocyte ratio (NLR) in the outcome of SCI. METHOD In a retrospective cross-sectional study from April 2019 to April 2022, all patients 18 to 65 years old, following spinal cord injury who were referred to Imam Khomeini Hospital and met inclusion and exclusion criteria enrolled in the study. A checklist including demographic data, lab, and clinical findings at admission, 24h, 48 h, and discharge were recorded. IBM SPSS Statistics software was used to analyze the data. A P-value of less than 0.05 was considered significant. RESULTS Six hundred patients met our inclusion criteria and enrolled in the study. The mean age of the patients was 40.93 ± 12.77, with 75% male and 25% female. There was a significant correlation between the N/L ratio at different time points (p.value=0.001), injury type, and ASIA score at admission and discharge (0.001). Furthermore, the NLR had approached significant value alone to predict outcomes in patients enrolled in the study (0.06). CONCLUSIONS A high NLR is unequivocally linked with poor outcomes in patients suffering from acute SCI and should be considered a negative prognostic factor; however, the NLR had approached significant predicting value in patients enrolled in the study.

Abstract
Pneumolysin (Ply) is a target for the development of serotype-independent pneumococcal vaccines, an important condition for the efficacy of which is their ability to activate innate immunity with the subsequent formation of adaptive immunity. In this study, the ability of recombinant full-length Ply (rPly) of pneumococci to induce TLR expression and maturation of dendritic cells generated from mouse bone marrow was evaluated. It was shown that rPly in vitro increased the number of dendritic cells expressing Toll-like receptor 4 (TLR4) on the membrane. rPly caused maturation of dendritic cells generated from mouse bone marrow, which manifested in a decrease in the number of progenitor cells (CD34), an increase in the number of cells expressing the adhesion molecule CD38, costimulatory molecules CD80 and CD86, molecules of terminal differentiation of dendritic cells CD83, as well as molecules of antigenic presentation of the major histocompatibility complex class II.

Evaluation of the Optimal Number of Implanted Mesenchymal Stem Cells for the Treatment of Post-Traumatic Syrinx and Recovery of Motor Activity after Chronic Spinal Cord Injury. Bull Exp Biol Med 2023; 175:557-568. [PMID: 37773573 DOI: 10.1007/s10517-023-05904-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Indexed: 10/01/2023]
Abstract
The present work aims at determining the most effective dose (number) of mesenchymal stem cells (MSC) for its transplantation in order to treat chronic spinal cord injury (SCI) in mature Sprague-Dawley rats (n=24). MSC were obtained from bone marrow of 4-6-month-old Sprague-Dawley rats. Four weeks after SCI, MSC suspension (4 μl) was injected to experimental animals into the injured area in doses of 4×105, 8×105, or 106. Using MRI, diffusion tensor imaging (DTI), diffusion tensor tractography (DTT), immunohistochemistry, histological staining, and behavioral tests, we studied the effect of transplantation of MSC in different doses on the following parameters in rats with SCI: the size of lesion cavity and post-traumatic syrinx (PTS), glial scar formation, neuronal fibers remodeling, axonal regeneration and sprouting, vascularization, expression of neuronal factors, and motor functions. MSC administration improved motor function in rats after SCI due to stimulation of regeneration and sprouting of the axons, enhanced recovery of locomotor functions, reduction of PTS and the glial scar, and stimulation of vascularization and expression of the neurotrophic factors. The effects of MSC were dose-dependent; the most effective dose was 106 cells.

Abstract
Traumatic or non-traumatic spinal cord injury (SCI) can lead to severe disability and complications. The incidence of SCI is high, and the rehabilitation cycle is long, which increases the economic burden on patients and the health care system. However, there is no practical method of SCI treatment. Recently, transcranial magnetic stimulation (TMS), a non-invasive brain stimulation technique, has been shown to induce changes in plasticity in specific areas of the brain by regulating the activity of neurons in the stimulation site and its functionally connected networks. TMS is a new potential method for the rehabilitation of SCI and its complications. In addition, TMS can detect the activity of neural circuits in the central nervous system and supplement the physiological evaluation of SCI severity. This review describes the pathophysiology of SCI as well as the basic principles and classification of TMS. We mainly focused on the latest research progress of TMS in the physiological evaluation of SCI as well as the treatment of motor dysfunction, neuropathic pain, spasticity, neurogenic bladder, respiratory dysfunction, and other complications. This review provides new ideas and future directions for SCI assessment and treatment.

Abstract
Military personnel are often exposed to silica dust during combat operations across the globe. Exposure to silica dust in US military or service personnel could cause Desert Strom Pneumonitis also referred to as Al Eskan disease causing several organs damage and precipitate autoimmune dysfunction. However, the effects of microfine particles of sand inhalation-induced brain damage on the pathophysiology of traumatic brain or spinal cord injury are not explored. Previously intoxication of silica nanoparticles (50-60 nm size) is shown to exacerbates spinal cord injury induces blood-spinal cord barrier breakdown, edema formation and cellular changes. However, the mechanism of silica nanoparticles-induced cord pathology is still not well known. Spinal cord injury is well known to alter serotonin (5-hydroxytryptamine) metabolism and induce oxidative stress including upregulation of nitric oxide synthase and tumor necrosis factor alpha. This suggests that these agents are involved in the pathophysiology of spinal cord injury. In this review, we examined the effects of combined nanowired delivery of monoclonal antibodies to neuronal nitric oxide synthase (nNOS) together with tumor necrosis factor alpha (TNF-α) antibodies and a potent antioxidant H-290/51 to induce neuroprotection in spinal cord injury associated with silica nanoparticles intoxication. Our results for the first time show that co-administration of nanowired delivery of antibodies to nNOS and TNF-α with H-290/51 significantly attenuated silica nanoparticles-induced exacerbation of spinal cord pathology, not reported earlier.
