2. 1. Macrocyclic polypeptides from plants

   Author : Ulf Göransson; David Craik; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmacognosy; Farmakognosi;

   Abstract : The aim of this work was to explore the structural and functional diversity of polypeptides that are found in plants. Expanding knowledge of simililarities between plant use of these compound and animal use promises exceptional opportunities for finding, from plant research, new structures with biomedical and biotechnological potential.

4. 2. Midkine - a host defence protein

   Author : Sara Nordin; allergologi och palliativ medicin Lungmedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antimicrobial polypeptides; Midkine; antibacterial; antifungal; innate immunity; epithelial surfaces;

   Abstract : Every day we encounter many potentially harmful microbes in our environment. The epithelial linings constitute an anatomical barrier protecting us and they also produce antimicrobial polypeptides (AMPs) that act as a chemical barrier. These AMPs are small and positively charged, killing a broad range of microbes rapidly. READ MORE

5. 3. Antibacterial Surfaces for Biomedical Applications

   Author : Saba Atefyekta; Chalmers tekniska högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; contact killing surfaces; antibiotic delivery; Antibacterial surfaces; Infection; mesoporous titania; Elastin-like polypeptides; antimicrobial peptides;

   Abstract : Medical devices such as orthopedic implants are intended to serve for improved quality of life. However, clinical success cannot be taken for granted and the most common reason for failure is due to biomaterials associated infection (BAI). READ MORE

6. 4. Antimicrobial polypeptides and lipids as a part of innate defense mechanism of fish and human fetus

   Author : Gudmundur Bergsson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Animals are constantly threatened by vast numbers of microbes and have consequently evolved an array of strategies to prevent microbial invasion. In this thesis, I have studied natural antimicrobial lipids and polypeptides associated with immediate host defense. READ MORE

7. 5. Expression and regulation of antimicrobial peptides in mucosal immunity

   Author : Andreas Cederlund; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Antimicrobial polypeptides (AMPs) are effector molecules of the innate immune defense. AMPs are mainly expressed in epithelial cells and immune cells, providing the first line of defense to infection as direct antimicrobials. In addition, many AMPs display immunomodulatory functions in both the adaptive and innate immune system. READ MORE
