Gene expression profile of thalamus based on RNA-seq

ABSTRACT: The impact of neurons on the pathogenesis of central poststroke pain (CPSP) after thalamic hemorrhage is currently unknown. The aim of this study was to identify the key genes in neurons and investigate their roles in pain after thalamic hemorrhage based on RNA-sequencing (RNA-seq) data from model mice.

The effect of an NAT10 inhibitor (remodelin) on inflammation-related genes in the treatment of thalamic hemorrhage based on proteomics data

Project description:Thalamic hemorrhage is a disease caused by hemorrhage of the thalamic brain parenchyma and is accompanied by an inflammatory response during development. NAT10 has been associated with a wide range of diseases. The aim of this study was to explore the molecular mechanisms associated with the use of the NAT10 inhibitor (Remodelin) for the treatment of thalamic hemorrhage from an inflammatory perspective.

Sustained neuronal stimulation activates paraventricular thalamus astrocytes for maintenance of chronic neuropathic pain in mice

Project description:Ongoing nociceptive inputs from peripheral tissues and nerve injuries lead to maladaptive alterations in central nervous system, which drive the transition from acute to chronic pain. Although astrocytes act as dynamic and active players in neuropathic pain states, the contribution of astrocytes in upper brain nucleus in this process remains unclear. Here, we revealed that prolonged neuronal inputs induced by periphery injury leads to astrocyte reactive and downregulation of inward rectifying potassium channel protein 4.1 (Kir4.1) in paraventricular thalamus（PVT）. In turn, reactive PVT astrocytes could maintain the hyperexcitability of neurons, and enhanced projections from PVT to medial prefrontal cortex (mPFC) in the chronicity of neuropathic pain. Notably, we identify a neuro-glial interaction mediating pain chronification in PVT, and clarified Kir4.1 channels as a potential therapeutic target for neuropathic pain treatment.

A genetically defined mPFC-thalamic circuit underlies pain chronicity

Project description:Chronic pain is a major health care problem with great social and economic consequences. Although the medial prefrontal cortex (mPFC) and the thalamus have been implicated in regulating pain, whether and how these regions may involve in pain chronification process have remained largely unknown. Here, we show that Foxp2+ neurons in mPFC, which are corticothalamic (CT) neurons representing the major mPFC output to thalamus, are deactivated in chronic inflammatory pain. Interestingly, prolonged, but not short-term, inactivation of the Foxp2+ neurons in mPFC increases the sensitivity to noxious stimulations. Conversely, chemogenetic activation of this neuronal cluster induces robust antinociceptive effects in both naïve mice and mice with chronic inflammatory pain. Furthermore, we found that the mPFC Foxp2+ neurons project to several thalamic relay nuclei and that activation of the mPFC to the parataenial nucleus of thalamus (PTN) circuit relieves pain. Finally, RNA-seq of the mPFC Foxp2+ neurons revealed that many genes related to neuronal activity are dysregulated in mice with chronic inflammatory pain. Collectively, our studies revealed that Foxp2+ neurons in mPFC that project to thalamus play a critical role in somatosensory processing and pain chronification.

Embryonic sensory thalamus nuclei-specific genes revealed by genetic labelling and FACS isolation

Project description:To identify genes expressed in specific developing thalamic nuclei during embryonic stages, a genetic dual labelling strategy was established to mark and isolate the cells. Transcription profiles were determined for the principal sensory thalamic populations by genome-wide analysis. We identified genes expressed in distinct thalamic nuclei with a potential function in the specification of individual sensory-modality thalamocortical connections.

Transcription profiling of monkey thalamus

Project description:Nuclei of the mammalian thalamus are aggregations of neurons with unique architectures and input-output connections, yet the molecular determinants of their organizational specificity remain unknown. By comparing expression profiles of thalamus and cerebral cortex in adult rhesus monkeys we identified transcripts that are unique to dorsal thalamus or to individual nuclei within it. Real-time quantitative polymerase chain reaction and in situ hybridization analyses confirmed the findings. Expression profiling of individual nuclei microdissected from the dorsal thalamus revealed additional subsets of nucleus-specific genes. Functional annotation using Gene Ontology (GO) vocabulary and Ingenuity Pathway analysis revealed over-representation of GO categories related to development, morphogenesis, cell-cell interactions, and extracellular matrix within the thalamus- and nucleus-specific genes-many involved in the Wnt signaling pathway. Examples included the transcription factor TCF7L2, localized exclusively to excitatory neurons, a calmodulin-binding protein PCP4, the bone extracellular matrix molecules SPP1 and SPARC, and other genes involved in axon outgrowth and cell matrix interactions. Other nucleus-specific genes such as CBLN1 are involved in synaptogenesis. The genes identified likely underlie nuclear specification, cell phenotype and connectivity during development and their maintenance in the adult thalamus. Experiment Overall Design: To determine the molecular underpinnings of nuclear specificity in the dorsal thalamus we isolated micro-punches of tissue from nucleus-specific regions and processed them for microarray analysis. Replicate samples from 5 separate dorsal thalamic nuclei were processed and compared to identify genes unique to each region. Affymetrix U133A Gene Chips were used. All of the samples were isolated from untreated adult monkey brain.

Fusion of Human Brain Organoids Assembles Bidirectional Connectivity Between Thalamus and Cortex

Project description:Human brain organoid techniques have rapidly advanced to facilitate investigating human brain development and diseases. Recent reports in generation and fusion of regionally defined brain organoids provide further opportunities to investigate the specific brain domains and their interactions. Focus of brain organoids has been to generate telencephalon due to its direct relevance in a variety of forebrain disorders. Despite its importance as a relay hub between cortex and peripheral tissues, the investigation of three-dimensional (3D) organoid model for the human thalamus has not yet been explored. Here, we describe a method to differentiate human embryonic stem cells (hESCs) to the thalamic organoids (hThOs) that specifically recapitulate the development of thalamus. Single-cell RNA sequencing (scRNA-seq) revealed a formation of distinct thalamic lineage cells, a lineage divergence from telencephalic lineage. Importantly, we developed a 3D system to create the reciprocal projections between thalamus and cortex by fusing the two distinct region-specific organoids representing the developing thalamus or cortex. Our study provides a platform for understanding human thalamic development and modeling circuit organizations and related disorders in the brain.

CircRNA Expression Profiling of the Rat Thalamus In Temporomandibular Joint Chronic Inflammatory Pain

Project description:Differential expression of circular RNAs (DEcircRNAs) in the thalamus, a relay station of the orofacial pain transmission pathway, may play an important role in inflammation and inflammatory pain progression in TMJOA and serve as a potential marker for its targeting. In this study, we obtained the expression profile of circRNAs from the thalamus of the rat TMJOA model by high-throughput sequencing to explore the potential role of circRNA in TMJOA inflammation and chronic inflammatory pain progression and their potential as new targeted molecular markers. Additionally, providing new clues to unravel the molecular mechanisms of chronic orofacial pain, providing insights into the potential roles of circRNAs in pain modulation, and paving the way for future research in this area.
