GSE115565 Human iPSC-derived GABAergic Interneuron Transplants Attenuate Neuropathic Pain

Contributor : John ManionSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensNeuropathic pain causes severe suffering and most patients are resilient to current therapies. A core element of neuropathic pain is the loss of inhibitory tone in the spinal cord. Previous studies have shown that foetal GABAergic neuron precursors can provide relief from pain. However, the source of these precursor cells and their multipotent status make them unsuitable for therapeutic use. Here we extend these findings by showing, for the first time, that spinally transplanted, terminally differentiated hiPSC-derived GABAergic (iGABAergic) neurons provide significant, long-term and safe relief from neuropathic pain induced by peripheral nerve injury in mice. Furthermore, iGABAergic Neuron transplants survive long term in the injured spinal cord and show evidence of synaptic integration. Together, this provides the proof in principle for the first viable GABAergic transplants to treat human neuropathic pain patients.

CONCLUSION: OECs and OECs-CS transplantation can inhibit P2X7R overexpression mediated NPP, while OECs-CS transplantation has better therapeutic effect than OECs transplantation alone. Our results provide a novel method and theoretical basis for the treatment of NPP. PMID: 32888912 [PubMed - as supplied by publisher]

Abstract Spinal cord injury (SCI) produces both locomotor deficits and sensory dysfunction that greatly reduce the overall quality of life. Mechanisms underlying chronic pain include increased neuro-inflammation and changes in spinal processing of sensory signals, with reduced inhibitory GABAergic signaling a likely key player. Our previous research demonstrated that spinal transplantation of GABAergic neural progenitor cells (NPCs) reduced neuropathic pain while intensive locomotor training (ILT) could reduce development of pain and partially reverse already established pain behaviors. Therefore, we evaluate the ...

Abstract OBJECTIVES: The aim of this study was to determine the role of microencapsulated olfactory ensheathing cells (MC-OECs) transplantation in rats with sciatic nerve injury-induced neuropathic pain, and its relationship with P2X4 receptor expression in the L4-5 spinal cord segment. METHODS: Olfactory bulb tissues of healthy Sprague Dawley (SD) rats were collected to culture olfactory ensheathing cells (OECs) using differential attachment methods. Seventy-two healthy SD rats were randomly assigned to four groups: the sham, chronic constriction injury (CCI), OECs, and MC-OECs groups. Mechanical paw withdra...

Abstract Neuropathic pain after spinal cord injury (SCI) is a complex condition that responds poorly to usual treatments. Cell transplantation represents a promising therapy; nevertheless, the ideal cell type in terms of neurogenic potential and effectiveness against pain remains largely controversial. Here, we evaluated the ability of fetal neural stem cells (fNSC) to relieve chronic pain and, secondarily, their effects on motor recovery. Adult Wistar rats with traumatic SCI were treated, 10 days after injury, with intra-spinal injections of culture medium (sham) or fNSCs extracted from telencephalic vesicles (TV...

This study also found that Proteus DNA, a genus with many uropathogenic species (Drzewiecka, 2016), was more prevalent in women with OAB compared to asymptomatic controls (Curtiss et al., 2017). IC A recent study by Abernethy et al. suggested that the microbiome may play a role in IC (Abernethy et al., 2017). In this study, 16S rRNA analysis determined the microbiome of catheterized urine from women (n = 40) with IC was not dominated by a single genus and was less likely to contain Lactobacillus compared to asymptomatic women. Abernethy et al. also showed that L. acidophilus was associated with less severe scores on the ...

Conclusion and Future Aspects This review summarizes available NTF expression data, compiles existing evidence on the effects of glial NTF signaling in healthy conditions and in disease models (Figure 1), and highlights the importance of this topic for future studies. The relationship between NTFs and glia is crucial for both the developing and adult brain. While some of these factors, such as NT-3 and CNTF, have highly potent effects on gliogenesis, others like BDNF and GDNF, are important for glia-mediated synapse formation. Neurotrophic factors play significant roles during neurodegenerative disorders. In many cases, ...
