  1. 1. Deciphering neural networks in the somatosensory system using single-cell transcriptomics and rabies tracing

    Författare :Jon E. T. Jakobsson; Malin C. Lagerström; Victoria Abraira; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; neural networks; somatosensory system; itch; rabies tracing; scRNA-seq;

    Sammanfattning : Itch has evolved to protect us from malicious parasites keen to suck our blood or lay their eggs in our skin. We can detect both the movement of these parasites and the toxins they introduce with specialized neurons called pruriceptors. When we feel an itch, we get a desire to scratch it. LÄS MER

  2. 2. In vivo properties of neural stem cells after transplantation into the rat brain-Studies of phenotypic differentiation and functional integration using cell-specific labelling and electrophysiological techniques

    Författare :Ulrica Englund Johansson; Peter Eriksson; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cell line; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; functional integration; electrophysiology; retrograde tracing; immortalized; GFP; migration; axonal projections; glia; neuron; transplantation; stem cell. progenitor cell; CNS; Biomedical Sciences;

    Sammanfattning : In the present thesis, we have examined the in vivo properties of in vitro expanded human and rat neural stem-and progenitor cells after transplantation into the neonatal and adult rat brain. The survival and differentiation of the grafted cells were assessed using species-specific antisera, and pre-labelling with the reporter gene green fluorescent protein (GFP). LÄS MER

  3. 3. Immunofluorescence Investigation on Neuroendocrine Secretory Protein 55 (NESP55) in Nervous Tissues

    Författare :Yongling Li; Göteborgs universitet; []
    Nyckelord :NESP55; neuropeptdides; chromogranins; the CAD cell line; rat; spinal cord; sympathetic ganglia; retrograde tracing; immunofluorescence; confocal microscopy; secretory pathway;

    Sammanfattning : The chromogranin family is a group of acidic, soluble, and heat-stable proteins widespread in various neuronal, neuroendocrine and endocrine tissues, where they are subcellullarly located in the secretory granules, participating in the formation of the granules. Extracellularly, chromogranins may act as protein precursors, proteolytically processed to various small bioactive peptides. LÄS MER

  4. 4. Neuronal types and their specification dynamics in the autonomic nervous system

    Författare :Alessandro Furlan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The autonomic nervous system is formed by a sympathetic and a parasympathetic division that have complementary roles in the maintenance of body homeostasis. Autonomic neurons, also known as visceral motor neurons, are tonically active and innervate virtually every organ in our body. LÄS MER

  5. 5. Neuronal tracers for fine caliber spinal primary afferents and their response to peripheral nerve injury

    Författare :H Fredrik Wang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Rat; Primary afferents; Dorsal root ganglion; Peripheral nerve injury; Spinal cord; Isolectin GSA I-B4; Soybean agglutinin; Cholera toxin B subunit; Horseradish peroxidase; Immunohistochemistry; Neuronal tracing;

    Sammanfattning : The isolectin B4 from Griffonia simplicifolia I (B4) and soybean agglutinin from the plant Glycine max (SBA), have been shown to bind to rat small-diameter dorsal root ganglion (DRG) neurons, and to fibers and presumed terminals in laminae I-II of the spinal cord dorsal horn. In the present thesis, these lectins and/or their horseradish peroxidase (HRP) conjugates, have been investigated in the rat with regard to their usefulness as selective neuronal markers of and axonally transported tracers for somatic and/or visceral spinal primary afferents with fine caliber, including unmyelinated, axons.
