1. Opioid ligands and receptors of the joint
Sammanfattning : The aim was to explore the occurrence of an opioid system in joints. Thus, joint tissues from rats with and without arthritis and also from patients with knee osteoarthrosis were investigated by EM, immunohistochemistry, RIA, HPLC, receptor binding assay and RT-PCR. LÄS MER
2. The opioid peptide dynorphin A : Biophysical studies of peptide–receptor and peptide–membrane interactions
Sammanfattning : The work presented in this thesis concerns the opioid peptide dynorphin A (DynA). DynA functions primarily as a neurotransmitter and belongs to the family of typical opioid peptides. These peptides are a part of the opioid system, together with the opioid receptors, a family of GPCR membrane proteins. LÄS MER
3. Evolution of the Neuropeptide Y and Opioid Systems and their Genomic Regions
Sammanfattning : Two whole genome duplications (2R) occurred early in vertebrate evolution. By using combined information from phylogenetic analyses and chromosomal location of genes, this thesis delineates the evolutionary history of two receptor-ligand systems that expanded by these large scale events.

4. Sperm Membrane Channels, Receptors and Kinematics : Using boar spermatozoa for drug toxicity screening
Sammanfattning : Internal fertilization usually implies that a spermatozoon, with intact attributes for zygote formation, passes all hurdles during its transport through the female genitalia and reaches the oocyte. During this journey, millions to billions of other spermatozoa perish. LÄS MER
5. Opioid and non-opioid activities of the dynorphins
Sammanfattning : Endogenous opioid peptides a-neoendorphin, dynorphin A (Dyn A), dynorphin B (Dyn B) and big dynorphin (Big Dyn) consisting of Dyn A and Dyn B, collectively known as dynorphins are derived from the precursor protein prodynorphin (PDYN). Dynorphins regulate pain processing and memory acquisition and modulate reward induced by intake of addictive substances. LÄS MER
