1. 6. Aspects on the psychopharmacology of cholecystokinin

   Författare :Diana Radu; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Cholecystokinin; brain; tripeptidyl-peptidase II; CCK receptors; schizophrenia; anxiety; stress; rat; monkey; human; pentagastrin; C-peptide; mRNA;

   Sammanfattning : This thesis includes studies of the effect of mild stress on brain cholecystokinin (CCK), anatomy of markers for CCK-ergic transmission in the brain and the systemic effect of CCK receptor stimulation in a clinical test for anxiety and fear. CCK is a brain-gut peptide acting as a neurotransmitter in mammalian brain via CCKA (CCK1) and CCKB (CCK2) receptors. LÄS MER

4. 8. Cholecystokinin, dopamine and glutamate in subcortical and peripheral control of food intake

   Författare :Min Qian; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :cholecystokinin; dopamine; glutamate; food intake;

   Sammanfattning : This thesis analyzes some of the mechanisms whereby cholecystokinin octapeptide (CCK-8) inhibits food intake in male rats. Depletion of monoamines using reserpine blocked the capacity for ingestive responses. These responses were restored in reserpinized rats by treatment with the non-competitive N-methyl-D-aspartate receptor antagonist MK-801. LÄS MER

5. 9. Regulation of the exocrine pancreas in growing pigs, with special emphasis on entero-pancreatic reflexes

   Författare :Lena Evilevitch; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; kidney bean lectin; Animal physiology; Djurfysiologi; duodenum; entero-pancreatic reflex; insulin; lipas; amylas; trypsin; weaning; development; maturation; inhibition; CCK-receptors; Exocrine pancreas; CCK; pig;

   Sammanfattning : The regulation of the exocrine pancreas has been under thorough investigation for many decades. In rats, cholecystokinin (CCK) is considered to be the major gut hormone stimulating the pancreas to releasing the digestive enzymes. LÄS MER

7. 10. On cholecystokinin-opioid interaction in the spinal dorsal horn following peripheral nerve injury and inflammation

   Författare :Guilherme de Araújo Lucas; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Cholecystokinin; Cholecystokinin receptors; Morphine; Spinal cord; Axotomy; Inflammation; Peptide release; Morphine tolerance; [my]-opioid receptor; Flexor reflex; Microdialysis;

   Sammanfattning : The peptide cholecystokinin (CCK) antagonizes opioid-induced analgesia. Conversely, antagonists of CCK receptors enhance the analgesic effect of opioids. Together, these results support a role for CCK as an anti-opioid peptide in pain mechanisms. LÄS MER
