1. Novel Endogenous Antimicrobial Peptides
Sammanfattning : Antimicrobial peptides serve as a first line of defence against invading microorganisms and are an essential part of our fast innate immune system. They are ancient molecules found in all classes of life. Antimicrobial peptides rapidly kill a broad spectrum of microbes and are immunomodulatory, i.e. LÄS MER
2. Cerebrospinal fluid peptidomics: discovery of endogenous peptides as biomarkers of Alzheimer's disease
Sammanfattning : Neurodegenerative diseases (NDs), the most prominent example of which is Alzheimer’s disease (AD), has turned out to be among the greatest challenges for modern medicine. Common characteristics of NDs involve the aggregation of proteins, progressive loss of neuronal cells in specific regions of the central nervous system (CNS) and as a result – cognitive and/or functional decline.

3. Vascular actions of antimicrobial peptides
Sammanfattning : The present thesis focuses on the vascular effects of antimicrobial peptides especially mechanisms involving the vasodilator nitric oxide (NO), which is released from the blood vessel wall during inflammatory conditions such as sepsis. Bacterial lipopolysaccharide stimulates the expression of nitric oxide synthase (iNOS), which increases the NO production in vascular tissues or cultured vascular smooth muscle cells (VSMC). LÄS MER
4. On inflammatory cytokines and β-amyloid peptides in acute and chronic neurodegeneration
Sammanfattning : Insults to the brain as well as neurodegenerative diseases are known to elicit inflammatory responses. Inflammation in the brain can on one hand initiate processes that are harmful to the injured tissue and exacerbate the damage, leading to neuronal degeneration and glial activation, and on the other hand activate processes that may be necessary for repair mechanisms and regeneration.

5. Methods and detection of endogenous peptides in the CNS and GI tract
Sammanfattning : Endogenous peptides, such as enkephalins, endorphins and orexins modulate a variety of biological processes; these peptides are found in the central nervous system and periphery, including the gastrointestinal tract. One of the methods commonly used to determine localization, concentration, expression and function of endogenous peptides is the radio immunoassay (RIA). LÄS MER
