Antidepressant Low Doses of Ketamine and Melatonin in Combination Produce Additive Neurogenesis in Human Olfactory Neuronal Precursors. Molecules 2022; 27:molecules27175650. [PMID: 36080418 PMCID: PMC9458007 DOI: 10.3390/molecules27175650] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Revised: 07/25/2022] [Accepted: 08/07/2022] [Indexed: 01/18/2023] Open
Abstract
Melatonin (MEL), an indolamine with diverse functions in the brain, has been shown to produce antidepressant-like effects, presumably through stimulating neurogenesis. We recently showed that the combination of MEL with ketamine (KET), an NMDA receptor antagonist, has robust antidepressant-like effects in mice, at doses that, by themselves, are non-effective and have no adverse effects. Here, we show that the KET/MEL combination increases neurogenesis in a clone derived from human olfactory neuronal precursors, a translational pre-clinical model for effects in the human CNS. Neurogenesis was assessed by the formation of cell clusters > 50 µm in diameter, positively stained for nestin, doublecortin, BrdU and Ki67, markers of progenitor cells, neurogenesis, and proliferation. FGF, EGF and BDNF growth factors increased the number of cell clusters in cultured, cloned ONPs. Similarly, KET or MEL increased the number of clusters in a dose-dependent manner. The KET/MEL combination further increased the formation of clusters, with a maximal effect obtained after a triple administration schedule. Our results show that the combination of KET/MEL, at subeffective doses that do not produce adverse effects, stimulate neurogenesis in human neuronal precursors. Moreover, the mechanism by which the combination elicits neurogenesis is meditated by melatonin receptors, CaM Kinase II and CaM antagonism. This could have clinical advantages for the fast treatment of depression.

Pharmacological inhibition of DNA methyltransferase 1 promotes neuronal differentiation from rodent and human nasal olfactory stem/progenitor cell cultures. Int J Dev Neurosci 2017; 58:65-73. [PMID: 28161254 DOI: 10.1016/j.ijdevneu.2017.01.013] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2016] [Revised: 01/28/2017] [Accepted: 01/29/2017] [Indexed: 01/09/2023] Open
Abstract
Nasal olfactory stem and neural progenitor cells (NOS/PCs) are considered possible tools for regenerative stem cell therapies in neurodegenerative diseases. Neurogenesis is a complex process regulated by extrinsic and intrinsic signals that include DNA-methylation and other chromatin modifications that could be experimentally manipulated in order to increase neuronal differentiation. The aim of the present study was the characterization of primary cultures and consecutive passages (P2-P10) of NOS/PCs isolated from male Swiss-Webster (mNOS/PCs) or healthy humans (hNOS/PCs). We evaluated and compared cellular morphology, proliferation rates and the expression pattern of pluripotency-associated markers and DNA methylation-associated gene expression in these cultures. Neuronal differentiation was induced by exposure to all-trans retinoic acid and forskolin for 7 days and evaluated by morphological analysis and immunofluorescence against neuronal markers MAP2, NSE and MAP1B. In response to the inductive cues mNOS/PCs expressed NSE (75.67%) and MAP2 (35.34%); whereas the majority of the hNOS/PCs were immunopositive to MAP1B. Treatment with procainamide, a specific inhibitor of DNA methyltransferase 1 (DNMT1), increases in the number of forskolin'/retinoic acid-induced mature neuronal marker-expressing mNOS/PCs cells and enhances neurite development in hNOS/PCs. Our results indicate that mice and human nasal olfactory stem/progenitors cells share pluripotency-related gene expression suggesting that their application for stem cell therapy is worth pursuing and that DNA methylation inhibitors could be efficient tools to enhance neuronal differentiation from these cells.

Abstract
The neuronal loss associated with Alzheimer's disease (AD) affects areas of the brain that are vital to cognition. Although recent studies have shown that new neurons can be generated from progenitor cells in the neocortices of healthy adults, the neurogenic potential of the stem/progenitor cells of AD patients is not known. To answer this question, we compared the properties of glial progenitor cells (GPCs) from the cortices of healthy control (HC) and AD subjects. The GPCs from AD brain samples displayed reduced renewal capability and reduced neurogenesis compared with GPCs from HC brains. To investigate the mechanisms underlying this difference, we compared beta-catenin signaling proteins in GPCs from AD versus HC subjects and studied the effect of amyloid beta peptide (Abeta, a hallmark of AD pathology) on GPCs. Interestingly, GPCs from AD patients exhibited elevated levels of glycogen synthase kinase 3beta (GSK-3beta, an enzyme known to phosphorylate beta-catenin), accompanied by an increase in phosphorylated beta-catenin and a decrease in nonphosphorylated beta-catenin compared with HC counterparts. Furthermore. we found that Abeta treatment impaired the ability of GPCs from HC subjects to generate new neurons and caused changes in beta-catenin signaling proteins similar to those observed in GPCs from AD patients. Similar results were observed in GPCs isolated from AD transgenic mice. These results suggest that Abeta-induced interruption of beta-catenin signaling may contribute to the impairment of neurogenesis in AD progenitor cells.

Abstract
In recent decades, a wide spectrum of fetal and embryonic stem and progenitor cells were used for cell therapy of diseases of the central nervous system, but the olfactory glial ensheathing cells exhibited certain advantages due to their biological properties and capacity to stimulate regeneratory processes in spinal injury. The therapeutic effect of a heterogeneous complex of olfactory epithelial cells is more pronounced; apart from glial ensheathing cells, this complex includes fibroblasts, Schwann cells, stem and progenitor cells of this structure. The use of minimally invasive methods for isolation of human olfactory epithelial tissue is important for clinical practice, because they provide cells for autologous transplantation and rule out graft rejection immune reaction and the risk of transmission viral infection and transfer of genetic defects, which can be associated with allotransplantation.
