Adipose-derived stem cells (ADSCs) have the capacity to differentiate into neural precursor cells which can be used for nerve regeneration. However, their inherently low neurogenic differentiation efficiency limits further clinical applications. This study was designed to promote neurogenic differentiation efficacy of ADSCs via integrating conductive hydrogel-based microwells with electrical stimulation (ES). We hypothesize that ADSCs will differentiate more efficiently into neural precursor cells when electrically stimulated in conductive hydrogel microwells...

Cell proliferation and differentiation are interdependent processes. Here, we have asked to what extent the two processes of neural progenitor cell amplification and differentiation are functionally separated. Thus, we analyzed whether it is possible to rescue a defect of terminal differentiation in progenitor cells of the dentate gyrus, where new neurons are generated throughout life, by inducing their proliferation and/or their differentiation with different stimuli appropriately timed. As a model we used the Tis21 knockout mouse, whose dentate gyrus neurons, as demonstrated by us and others, have an intrinsic defect of terminal differentiation...

BACKGROUND: FTY720 (fingolimod, Gilenya™) is an oral, blood-brain barrier (BBB)-passing drug approved as immunomodulatory treatment for relapsing-remitting form of the multiple sclerosis (MS). In addition, FTY720 exerts several effects in the central nervous system (CNS), ranging from neuroprotection to reduction of neuroinflammation. However, the neurogenic and oligodendrogenic potential of FTY720 has been poorly investigated. In this study, we assessed the effect of FTY720 on the production of new neurons and oligodendrocytes from neural stem/precursor cells both in vitro and in vivo...

Orthostatic intolerance is defined as the provocation of symptoms upon standing, commonly caused by neurogenic orthostatic hypotension (OH) and postural tachycardia syndrome (POTS), the etiology for which has not been fully uncovered yet. Many reports have described the occurrence of dysautonomia, orthostatic intolerance and POTS following febrile illness, presumably viral and post-vaccine. Furthermore, patients with dysautonomia have higher rates of autoimmune disorders such as Hashimoto thyroiditis and SLE...

From birth to death, catecholamine secretion undergoes continuous adjustments, allowing the organism to adapt to homeostasis changes. To cope with these stressful conditions, the neuroendocrine cells of the adrenal medulla play an immediate and crucial role. Chromaffin cell-driven catecholamine release is chiefly controlled by a neurogenic command that arises from the sympathetic nervous system, which releases acetylcholine at the splanchnic nerve terminal-chromaffin cell synapses. In addition to receiving several synaptic inputs individually, chromaffin cells are coupled by gap junctions...

Abdominal pain is the foremost complication of chronic pancreatitis (CP). Pain can be related to recurrent or chronic inflammation, local complications or neurogenic mechanisms with corresponding changes in the nervous systems. Both pain intensity and the frequency of pain attacks have been shown to reduce quality of life in patients with CP. Assessment of pain follows the guidelines for other types of chronic pain, where the multidimensional nature of symptom presentation is taken into consideration. Quantitative sensory testing may be used to characterize pain, but is currently used in a research setting in advanced laboratories...

Interstitial cells of Cajal (ICC) isolated from the rabbit urethra exhibit Ca(2+)-activated Cl(-) currents (I ClCa) that are important for the development of urethral tone. Here, we examined if TMEM16A (ANO1) contributed to this activity by examining the effect of "new-generation" TMEM16A inhibitors, CACCinh-A01 and T16Ainh-A01, on I ClCa recorded from freshly isolated rabbit urethral ICC (RUICC) and on contractions of intact strips of rabbit urethra smooth muscle. Real-time quantitative PCR experiments demonstrated that TMEM16A was highly expressed in rabbit urethra smooth muscle, in comparison to TMEM16B and TMEM16F...

Neurogenesis is the process by which new neurons are generated. This process, well established during development, persists in adulthood owing to the presence of neural stem cells (NSCs) localized in specific brain areas called neurogenic niches. Adult neurogenesis has recently been shown to occur in the hypothalamus, a structure involved in the neuroendocrine regulation of reproduction and metabolism, among others. In the adult sheep-a long-lived mammalian model-we have previously reported the existence of such a neurogenic niche located in the hypothalamic arcuate nucleus and the median eminence...

Neural stem/progenitor cells (NPCs) generate new neurons in the brain throughout the lifetime in an intricate process called neurogenesis. Neurogenic alterations are a common feature of several adult-onset neurodegenerative diseases. The neuronal ceroid lipofuscinoses (NCLs) are the most common group of inherited neurodegenerative diseases that mainly affect children. Pathological features of the NCLs include accumulation of lysosomal storage material, neuroinflammation, and neuronal degeneration, yet the exact cause of this group of diseases remains poorly understood...

The ventral mesencephalic neural precursor cells (vmNPCs) that give rise to dopaminergic (DA) neurons have been identified by the expression of distinct genes (e.g., Lmx1a, Foxa2, Msx1/2). However, the commitment of these NPCs to the mesencephalic DA neuronal fate has not been functionally determined. Evaluation of the plasticity of vmNPCs suggests that their commitment occurs after E10.5. Here we show that E9.5 vmNPCs implanted in an ectopic area of E10.5 mesencephalic explants, retained their specification marker Lmx1a and efficiently differentiated into neurons but did not express the gene encoding tyrosine hydroxylase (Th), the limiting enzyme for dopamine synthesis...

INTRODUCTION: Bladder and bowel dysfunction (BBD) can negatively impact the quality of life (QoL) of children. Urotherapy is an accepted treatment option for BBD; however, literature that examines the impact of management options on QoL in this population is scarce. OBJECTIVE: To determine whether a bladder training video (BTV) is non-inferior to standard urotherapy (SU) in improving QoL in children with BBD. METHODS: Children aged 5-10 years and who scored ≥11 on the Vancouver Non-Neurogenic Lower Urinary Tract Dysfunction/Dysfunctional Elimination Syndrome Questionnaire (NLUTD/DES) were recruited from a pediatric tertiary care center...

Sustained increases in the activity of the sympathetic neural pathways that exit the brain and which increase blood pressure (BP) are a major underlying factor in resistant hypertension. Recently available information on the occurrence of angiotensin II type 2 receptors (AT2Rs) within or adjacent to brain cardiovascular control centers is consistent with findings that stimulation of these receptors lowers BP, particularly during hypertension of neurogenic origin. Until recently brain AT2R had not been considered by many to play a role in the central control of BP...

PURPOSE OF REVIEW: This review examines current terminology used to define non-neurogenic chronic urinary retention (CUR), describes the pathophysiology of urinary retention, and highlights contemporary diagnostic and treatment algorithms. RECENT FINDINGS: There is no standardized definition for the condition, but volumes >300 ml are commonly used to describe CUR. It is a clinical diagnosis which does not require urodynamics. Pathophysiologic causes of CUR be from myogenic, neurogenic, bladder outlet obstruction, or a combination of these sources...

Chronic diarrhea in infants is a common condition for addressability to pediatric gastroenterologists. The causes are multiple and the delay in reaching the final diagnosis can lead to complications in the general condition of the child. The purpose of this review is to present the bio-clinical and histogenetic particularities of a rare clinical entity, characterized by tumoral causes of chronic diarrhea. VIPomas are neuroendocrine tumors that autonomously secrete vasoactive intestinal peptide (VIP). Watery diarrhea, hypokalemia and achlorhydria (WDHA) syndrome caused by VIP-producing tumors only rarely occurs in adult patients with non-pancreatic disease...

Human induced pluripotent stem cells (hiPSCs) are invaluable to study developmental processes and disease mechanisms particularly in the brain. hiPSCs can be differentiated into mature and functional dopaminergic (DA) neurons. Having robust protocols for the generation of differentiated DA neurons from pluripotent cells is a prerequisite for the use of hiPSCs to study disease mechanisms, for drug discovery, and eventually for cell replacement therapy. Here, we describe a protocol for generating and expanding large numbers of homogeneous midbrain floor plate progenitors (mFPPs) that retain efficient DA neurogenic potential over multiple passages and can be cryobanked...

INTRODUCTION: The pathophysiology of pain in migraine is related to the activation of the trigeminovascular system by releasing vasoactive neuropeptides, the most important of which is calcitonin gene-related peptide (CGRP), which causes a neurogenic inflammation in the leptomeningeal vessels. AIM: To study whether CGRP is increased in frequent episodic migraine and whether preventive treatment with topiramate or zonisamide modifies its levels. SUBJECTS AND METHODS: We studied 28 patients with episodic migraine with or without aura, in accordance with the International Headache Society criteria, with a frequency of 4-14 days/month...
