Abstract
The neurobiology of autism is complex, but emerging research points to potential abnormalities and alterations in neurogenesis. The aim of the present review is to describe the advances in the understanding of the role of selected neurotrophins, neuropeptides, and other compounds secreted by neuronal cells in the processes of postnatal neurogenesis in conjunction with autism. We characterize the fundamental mechanisms of neuronal cell proliferation, generation of major neuronal cell types with special emphasis on neurogenic niches - the subventricular zone and hippocampal areas. We also discuss changes in intracellular calcium levels and calcium-dependent transcription factors in the context of the regulation of neurogenesis and cell fate determination. To sum up, this review provides specific insight into the known association between alterations in the function of the entire spectrum of molecules involved in neurogenesis and the etiology of autism pathogenesis.

ZHONGGUO DANG DAI ER KE ZA ZHI = CHINESE JOURNAL OF CONTEMPORARY PEDIATRICS 2021; 23:786-790. [PMID: 34511166 PMCID: PMC8428910 DOI: 10.7499/j.issn.1008-8830.2106042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Received: 06/11/2021] [Accepted: 07/05/2021] [Indexed: 06/13/2023]
Abstract
OBJECTIVES To study the clinical effect of mouse nerve growth factor (mNGF) in the treatment of children with global developmental delay (GDD). METHODS A prospective clinical trial was conducted in 60 children with GDD who were treated in the First Affiliated Hospital of Anhui Medical University between July 2016 and July 2017. These children were randomly divided into two groups: conventional rehabilitation treatment and mNGF treatment group (n=30 each). The children in the conventional rehabilitation treatment group were given neurodevelopmental therapy, and those in the mNGF treatment group were given mNGF treatment in addition to the treatment in the control group. The evaluation results of the Gesell Developmental Scale were compared between the two groups before and after treatment. RESULTS Before treatment and after 1.5 months of treatment, there was no significant difference in the developmental quotient (DQ) of each functional area of the Gesell Developmental Scale between the mNGF treatment and conventional rehabilitation treatment groups (P>0.05). After 3 months of treatment, the mNGF treatment group had significantly higher DQs of gross motor, fine motor, and personal-social interaction than the conventional rehabilitation treatment group (P˂0.05). The incidence rate of transient injection site pain after injection of mNGF was 7% (2/30), and there was no epilepsy or other serious adverse reactions. CONCLUSIONS In children with GDD, routine rehabilitation training combined with mNGF therapy can significantly improve their cognitive, motor, and social abilities.

Abstract
BACKGROUND Neural differentiation from embryonic stem cells (ESCs) is an excellent model for elucidating the key mechanisms involved in neurogenesis, and also provides an unlimited source of progenitors for cell-based nerve regeneration. However, the existing protocols such as small molecule substances, 3D matrix, co-culture technique and transgenic method, are complicated and difficult to operate, thus are limited by laboratory conditions. Looking for an easy-to-operate protocol with easily gained material and high induction efficiency has always been a hot issue in neuroscience research. NEW METHODS This paper established an optimized method for embryonic neurogenesis using a strategy of "combinatorial screening". In our study, the whole process of embryonic neurogenesis was divided into two phases, and the differentiation efficiency of seven experimental protocols in phase I and three protocols in phase II were systematically evaluated in A2lox and 129 ESCs. RESULTS In phase I differentiation, "2-day embryoid bodies formation + 6-day retinoic acid induction" (Phase I-protocol 3) could effectively induce the differentiation of ESCs into neural precursor cells (NPCs). Furthermore, in phase II, N2B27 medium II (Phase II-protocol 3) could better support the subsequent differentiation from NPCs into neurons. COMPARISON WITH EXISTING METHOD(S) Such a combinational method (phase I-protocol 3 and phase II-protocol 3) can realize embryonic neurogenesis with high efficiency, easy implementation and low-cost, and is suitable for promotion in most laboratories. CONCLUSIONS Through "combinatorial screening" strategy, we established an optimized method for embryonic neurogenesis in vitro, which is expected to be a powerful tool for neuroscience research.

Abstract
Environmental stressors in early childhood can have a detrimental impact later in life, manifesting in functional gastrointestinal disorders including irritable bowel syndrome (IBS). The phenomenon is also observed in rodents, where neonatal-maternal separation, a model of early life stress, induces phenotypes similar to IBS; however, the underlying mechanisms remain unelucidated. Our recent study provided a mechanism for the pathogenesis in the gut, demonstrating that increased visceral hyperalgesia resulted from the expansion of the intestinal stem cell compartment leading to increased differentiation and proliferation of serotonin (5-hydroxytryptamine/5-HT)-producing enterochromaffin cells. Moreover, it identified nerve growth factor (NGF) as a key mediator of the pathogenesis; surprisingly, it exerts its effect via cross talk with Wnt/β-catenin signaling. This article addresses the roles of NGF in driving IBS and its potential clinical implications, outstanding questions in how psychological stimuli are transduced into physical phenotypes, as well as future directions of our findings.

Abstract
General anesthesia with sevoflurane is associated with an increased incidence of postoperative cognitive dysfunction. Previous studies have shown that sevoflurane anesthesia can affect the integrity and function of basal forebrain cholinergic neurons (BFCNs) which are essential for learning and memory. However, the underlying mechanisms remain largely unknown. Here, we demonstrated that exposure to 2.5% sevoflurane induced significant loss of BFCNs and caused impairments of the spatial and the fear memory. Further, sevoflurane exposure significantly reduced the level of nerve growth factor (NGF), an important factor for the survival and phenotype maintenance of BFCNs, by disrupting its synthesis pathways in the brain. More importantly, NGF administration not only prevented the loss of BFCNs but also ameliorated the cognitive impairments in sevoflurane-treated mice. Our findings indicate that NGF metabolic dysfunction contributes to sevoflurane-associated BFCNs degeneration and subsequent cognitive deficits.

Abstract
Many therapies with potential for treatment of brain injury have been investigated. Few types of cells have spurred as much interest and excitement as stem cells over the past few decades. The multipotentiality and self-renewing characteristics of stem cells confer upon them the capability to regenerate lost tissue in ischemic or degenerative conditions as well as trauma. While stem cells have not yet proven to be clinically effective in many such conditions as was once hoped, they have demonstrated some effects that could be manipulated for clinical benefit. The various types of stem cells have similar characteristics, and largely differ in terms of origin; those that have differentiated to some extent may exhibit limited capability in differentiation potential. Stem cells can aid in decreasing lesion size and improving function following brain injury.
