2. 1. Effects of Inflammatory Mediators on Pulmonary Airways

   Author : Ofir Bachar; Klinisk och experimentell allergiforskning; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; electric ?eld stimulation; bradykinin; airway; tumor necrosis factor a; Respiratory system; nitric oxide; Andningsorganen; Toll-like receptor; prostaglandin E2; neurotrophin; allergy;

   Abstract : Chronic inflammation is together with excessive contraction of the airways key features of asthma. The aims of the thesis were to analyze the effect of inflammatory mediators on airway smooth muscle, using an in vitro model of cultured murine airways. READ MORE

4. 2. PACAP in adult sensory neurons - implications in injury and pain

   Author : Helen Jongsma Wallin; Institutionen för experimentell medicinsk vetenskap; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; peripheral nerve injury; PAC1; PACAP; neurotrophin; neuropeptide; inflammatory pain; inflammation; gracile nuclei; DRG; formalin test; neurofysiologi; neuropsykologi; Neurologi; neurophysiology; neuropsychology; Neurology; trk;

   Abstract : The data presented in this thesis deal with the neuropeptide pituitary adenylate cyclase-activating polypeptide (PACAP) in adult sensory neurons. We have used different injury and pain models to determine the involvement of PACAP during such conditions. The role of neurotrophins for PACAP expression was also investigated. READ MORE

5. 3. PACAP and orphanin FQ/nociceptin -Distribution, importance and regulation in sensory neurons and spinal cord

   Author : Lina Pettersson; Institutionen för experimentell medicinsk vetenskap; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; neuropsychology; Neurology; trk; spinal cord; sensory neuron; rat; PAC1; PACAP; ORL1; OFQ N; neurotrophin; neuropeptide; nerve transection; nerve compression; inflammatory pain; BDNF; DRG;

   Abstract : Neuropeptide expression in the nervous system is abundant and plastic, and an altered expression after injury is an example of a functional response, helping the neuron to cope with adverse changes, and involves effects on differentiation, synthesis, repair/regeneration, survival, and modulation of signal transmission. I have investigated the distribution/expression of the neuropeptides, orphanin FQ/nociceptin (OFQ/N) and pituitary adenylate cyclase activating polypeptide (PACAP), under normal conditions, in response to nerve injuries, and also studied sensory responses in mice deficient for the PAC1 receptor (PAC1-/-).

6. 4. Brain neurotrophin levels and mouse behavior : relationship to environmental influences

   Author : Shun-Wei Zhu; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Environmental Enrichment; Intermittent Individual Housing; Physical Exercise; Anxiety; NGF; BDNF; Dorsal Hippocampus; Ventral Hippocampus;

   Abstract : All normal functions over the lifetime of an animal are based on a dynamic balance of at least three fundamental elements: brain, environment and behaviour. This thesis investigated different aspects of these three elements and revealed novel interactions of brain neurotrophins, environmental influences and emotional behaviour in mice. READ MORE

7. 5. Role of Endogenous BDNF and NT3 for Synaptic Transmission and Plasticity in the Dentate gyrus

   Author : Klara Olofsdotter; Malmö Institutionen för kliniska vetenskaper; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hippocampus; dentate gyrus; GABA; glutamate; synaptic transmission; synaptic plasticity; Brain-derived neurotrophic factor; neurotrophin 3; Neurologi; neurophysiology; neuropsychology; Neurology; electrophysiology; neurofysiologi; neuropsykologi;

   Abstract : The neurotrophins, notably brain-derived neurotrophic factor (BDNF) and neurotrophin 3 (NT3), modulate synaptic transmission and synaptic plasticity in the adult mammalian brain. Recent data suggest that neurotrophins might be mediators of activity-dependent synaptic plasticity. READ MORE
