Single-cell transcriptional mapping of the developing human brainstem

ABSTRACT: The anatomical relationship of the brainstem is complex, which is the center of respiratory circulation in the human body. We used single cell RNA sequencing (scRNA-seq) to analyze the cellular molecular diversity of the fetal brainstem.

Effect of mild respiratory SARS-CoV-2 infection on brainstem endothelial transcriptome

Project description:To investigate the transcriptional response of brainstem endothelial cells to mild respiratory infection, 12-month-old male C57Bl/6 mice were intranasally inoculated with SARS-CoV-2 MA10 strain or with saline.

Brainstem Proteomics in Epilepsy and Sudden Unexpected Death in Epilepsy

Project description:Brainstem nuclei dysfunction is implicated in sudden unexpected death in epilepsy (SUDEP). In animal models, deficient serotonergic activity is associated with seizure-induced respiratory arrest. In humans, glia are decreased in the ventrolateral medullary pre-Botzinger complex that modulates respiratory rhythm, as well as in the medial raphe that modulates respiration and arousal. Finally, SUDEP cases have decreased midbrain volume. To understand the potential role of brainstem nuclei in SUDEP, we evaluated molecular signaling pathways using localized proteomics in microdissected midbrain dorsal raphe and medullary raphe serotonergic nuclei, as well as the ventrolateral medulla in brain tissue from epilepsy patients who died of SUDEP and other causes in diverse epilepsy syndromes, and non-epilepsy control cases

Single-nucleus sequencing data from developing and adult mouse olivocochlear neurons

Project description:Transcriptional diversity of mouse olivocochlear neurons (OCNs) was examined using single-nucleus sequencing of brainstem cholinergic neurons at P1, P5, and P26-P28. This dataset includes multiple brainstem cell types, including OCNs and several other populations of cranial motor neurons.

DNA methylation alteration and gene expression sigature in brainstem, thalamic, and supratentorial gliomas

Project description:Gliomas arising in the brainstem and thalamus are devastating tumors that are difficult to surgically resect due to their proximity to eloquent brain structures. Here, we performed a comprehesive genomic and epigenomic study, using gene expression and methylation microarrays, to research on th different genomic and epigenetic signatures between brainstem, thalamic, and supratentorial gliomas. Comparison of brainstem, thalamic and supratentorial gliomas

Caspase-3 cleaves extracellular vesicle proteins during auditory brainstem development

Project description:Sound localization requires extremely precise development of auditory brainstem circuits, the molecular mechanisms of which are largely unknown. We previously demonstrated a novel requirement for non-apoptotic activity of the protease caspase-3 in chick auditory brainstem development. Here, we used mass spectrometry to identify proteolytic substrates of caspase-3 during chick auditory brainstem development. Functional annotation analysis revealed that our caspase-3 substrates were enriched more than two-fold for proteins associated with extracellular vesicles (EVs), membrane-bound nanoparticles that function in intercellular communication. The proteome of EVs isolated from the auditory brainstem contained caspase-3 and was highly enriched for the caspase-3 substrates identified here. Additionally, we identified two caspase-3 substrates with known functions in axon guidance, namely Neural Cell Adhesion Molecule (NCAM) and Neuronal-glial Cell Adhesion Molecule (Ng-CAM), that were found in auditory brainstem EVs and expressed in the auditory pathway alongside cleaved caspase-3. Taken together, these data suggest a novel developmental mechanism whereby caspase-3 influences auditory brainstem circuit formation through the proteolytic cleavage of EV proteins.

Gene expression analysis in the Brainstem of Vglut2:Ndufs4cKO mice

Project description:Leigh Syndrome is characterized by symmetrical brain lesions and neuroinflammation in select nuclei, predominantly brainstem and/or basal ganglia. Accordingly, Ndufs4-deficient mice present overt lesions in brainstem, olfactory bulb, and basal ganglia. To define the contribution of Ndufs4 deficiency in excitatory neurons to the overall neuroinflammatory phenotype, we performed Gene expression analysis in the brainstem of mice with specific deletion of Ndufs4 in Vglut2-expressing neurons (Vglut2:Ndufs4cKO mice). This analysis allowed us to further define the inflammatory phenotype present in the brainstem of Vglut2:Ndufs4cKO mice.

MicroRNA expression data from brainstem gliomas

Project description:Gliomas arising in the brainstem are rare tumours worldwide that are difficult to surgically resect, and the involved miRNAs and signaling pathways associated with brainstem gliomas (BSGs) are largely unclear. Tumours in the control nervous system owned a WHO classification, which are of great significance to guide the treatment and to evaluate prognosis. To determine grade-associated miRNAs in BSGs, this study performed microarray of 10 low-grade and 15 high grade BSGs.

Molecular and functional profiling of cell diversity and identity in the lateral superior olive, an auditory brainstem center with ascending and descending projections

Project description:The lateral superior olive (LSO), a conspicuous integration center in the auditory brainstem, contains a remarkably heterogeneous neuron population. Ascending neurons, predominantly principal neurons (pLSOs), process interaural level differences for sound localization. Descending neurons (lateral olivocochlear neurons, LOCs) provide feedback into the cochlea and likely protect from acoustic overexposure. The molecular determinants of the neuronal diversity in the LSO are largely unknown. Here, we employed patch-seq analysis in juvenile mice to classify LSO neurons by their functional and molecular profiles, including developmental aspects. Across the sample (n=86), genes involved in ATPsynthesis were particularly highly expressed, confirming the energy expenditure of auditory neurons. Two clusters were identified, pLSOs and LOCs. They were distinguishable by 353 differentially expressed genes (DEGs), most being novel for the LSO. Electrophysiological analysis corroborated the transcriptomic clustering. We focused on genes impacting neuronal input-output properties and validated some by immunohistochemistry, electrophysiology, and pharmacology. These genes encode proteins like osteopontin, Kv11.3, and Kvb3 (pLSO-specific), calcitonin-gene-related peptide (LOC-specific), or Kv7.2 and Kv7.3 (no DEGs). We identified 12 ‘Super DEGs’ and 12 genes demonstrating ‘Cluster similarity’. Collectively, we provide fundamental and comprehensive insights into the molecular composition of individual ascending and descending neurons in the juvenile auditory brainstem and how this may relate to their specific functions, including developmental aspects.
