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

La chimie de clic est devenue indispensable dans les nombreux domaines de chimie associée à la conception de médicament. Dans ce contexte, comme nous savons(connaissons) l'étude concernant l'impact d'insertion triazole sur la conformation de peptaibol est limitée, nous avons conduit l'étude pour examiner l'impact et l'adaptabilité de 1, 1 4-disubstituted, 2, l'insertion 3-triazole dans peptaibols différent. Selon le résultat de cette expérience touchant à l'activité réduite et la conformation perturbée de l'analogue peptaibol, le substitut dipeptide décoré du fragment triazole portant substitu

Abstract:

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:

Les travaux présentés dans ce mémoire ont été motivés par l'importance économique de l'élevage de la crevette bleue du pacifique Litopenaeus stylirostris dont les fortes mortalités sont principalement dues au développement de maladies bactériennes et virales. Ils ont consisté en la caractérisation des deux premiers membres d'une famille originale de peptides multifonctionnels présents chez les crevettes pénéides, les stylicines. Ces peptides, nommés stylicines 1 et 2, sont des peptides anioniques (pI < 6.0), formés d'une région amino-terminale riche en résidus de type proline et d'une régio

Abstract:

My primary research interest is focused on the field of cellular electrical activity, ranging from the ion channels that generates it, up to the study of intracellular processes regulating it, and new generation of drugs. For this purpose, during my Ph.D. I have learnt and improved different cutting-edge techniques, i.e. the patch-clamp technique, the fluorescence imaging, and the synthesis and use of model membranes. Moreover, to explore particular aspects of these molecular mechanisms and to overcome the issues raised during the investigations, non-conventional strategies were employed, even

Abstract:

Thesis advisor: Jianmin Gao<br>As the threat of microbial resistance to antibiotics grows, we must turn in new directions to find new drugs effective against resistant infections. Antimicrobial peptides (AMPs) and host-defense peptides (HDPs) are a class of natural products that have been well-studied towards this goal, though very few have found success clinically. However, as there is much known about the behavior of these peptides, work has been done to manipulate their sequences and structures in the search for more drug-like properties. Additionally, novel sequences and structures mimicki

Abstract:

The goal of this project was to clone and express the antimicrobial peptide protegrin 1 (PG-1). Initially a yeast system was chosen but was discarded due to technical difficulties. Invitrogen's bacterial T7 expression system was chosen next to express the peptide. PG-1 expression was verified by anti-his immunoblot and then the peptide was purified by IMAC. Its activity was verified using a Bacillus subtillis radial diffusion assay.

Abstract:

Modern medicine is challenged continuously by the increasing prevalence of multi-drug resistant bacteria. Therefore, the development of alternatives to traditional antibiotics is an urgent necessity. Cationic antimicrobial peptides (CAMPs) are components of the innate immune defense system. Histones, generally known as proteins that package and regulate the transcription of DNA, share all of the essential antimicrobial traits of CAMPs, and could be promising alternatives to antibiotics. In this study, I investigated the antimicrobial properties of nucleated-erythrocyte-specific linker hist
