   Sammanfattning : The analysis of low abundant biological molecules is often challenging due to their chemical properties, low concentration and limited sample volumes. Neuropeptides are one group of molecules that fits these criteria. Neuropeptides also play an important role in biological functions, which makes them extra interesting to analyze. LÄS MER

   Sammanfattning : 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-/-).

5. 4. Neuropeptides and neurotrophic factors in epilepsy: seizure suppressant actions of VEGF, NPY and galanin

   Författare :Litsa Nikitidou; Lund Neurologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Epilepsy; Gene Therapy; Neuropeptide Y; Y2 receptor; Y5 receptor; Galanin; Encapsulated cell biodelivery; Vascular endothelial growth factor; Flk-1; Hippocampus;

   Sammanfattning : Epilepsy is a severe chronic neurological disorder, affecting about 1% of the population. The disease is manifested by spontaneous recurrent seizures, caused by hypersynchronized neuronal activity due to imbalance in the brain between the inhibition and excitation. LÄS MER

7. 5. PACAP in adult sensory neurons - implications in injury and pain

   Författare :Helen Jongsma Wallin; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER
