Abstract:
A detailed description of the characteristics of antimicrobial peptides (AMPs) is highly demanded, since the resistance against traditional antibiotics is an emerging problem in medicine. They are part of the innate immune system in every organism, and they are very efficient in the protection against bacteria, viruses, fungi and even cancer cells. Their advantage is that their target is the cell membrane, in contrast to antibiotics which disturb the metabolism of the respective cell type. This allows AMPs to be more active and faster. The lack of an efficient therapy for some cancer types and

Les organismes vivants produisent des peptides antimicrobiens (PAMs) pour se protéger contre les microbes. La résistance croissante aux antibiotiques nécessite le développement de nouvelles stratégies thérapeutiques et les PAMs sont des candidats prometteurs pour résoudre ce problème. Ils possèdent une activité à large spectre et leur principal mécanisme d'action par perméation de la membrane engendre peu de phénomènes de résistance. Néanmoins, leur faible biodisponibilité empêche leur utilisation. Certaines limitations peuvent être surmontées en développant des mîmes de PAMs qui conservent le

Abstract:
The emergence of antimicrobial resistance is a severe threat to global health and new classes of antibiotics are desperately needed. Peptoids, or oligo-N-substituted glycines, are a group of peptidomimetics with increased structural stability and resistance to protease degradation compared to peptide analogues. In Chapter 1, peptoids are introduced and their antimicrobial properties reported to date are summarised. The synthesis and characterisation of one of the largest library of antimicrobial peptoids in existence is outlined in Chapter 2, comprising linear sequences and cyclic compounds. T

Abstract:
This master thesis project was carried out at SP Technical Research Institute of Sweden within the FORMAMP project which goal is to increase the efficiency and stability of antimicrobial peptides (AMPs) by exploring and developing a number of innovative formulation strategies for the drug delivery of those systems. In view of the growing problem of bacterial resistance to traditional antibiotics, AMPs represent one of the most promising alternatives as therapeutics against infectious diseases: besides having a fast and non-specific mechanism of action, they are less prone to bacterial resistan

Abstract:
Nowadays, around a third of the agricultural production is lost due to the damage caused by pests, resulting in a significant economic impact. It is estimated that about a third of these losses are provoked by phytopathogens. Currently, the solution to these problems focuses on the use of pesticides, mainly copper derivatives, antibiotics or fungicides. These compounds are effective, but they are highly polluting. In addition, antibiotics are not allowed in many countries, because abusive use causes the rapid appearance of bacterial resistant strains. The lack of non-polluting and effective t

Abstract:
Since ticks are classified as hematophagous ectoparasites, the primary feeding event involves a bloodmeal on a vertebrate host. Such activities facilitate the ingestion of microorganisms which may be detrimental to the survival of a tick. It is observed, however, that ticks are able to survive such invasion by microorganisms and in several cases, facilitate the transmission of pathogens, while themselves remaining unaffected. This phenomenon is attributed to the innate immune system of ticks. The focus of this project is on stimulus-induced immunoreactive peptides known as antimicrobial peptid

Abstract:
Pseudomonas aeruginosa is a ubiquitous environmental Gram-negative bacterium that is also a major opportunistic human pathogen in nosocomial infections and cystic fibrosis chronic lung infections. These P. aeruginosa infections can be extremely difficult to treat due to the high intrinsic antibiotic resistance and broad repertoire of virulence factors, both of which are highly regulated. It was demonstrated here that the psrA gene, encoding a transcriptional regulator, was up-regulated in response to sub-inhibitory concentrations of antimicrobial peptides.
