1. 1. Microgel Interactions with Peptides and Proteins : Consequence of Peptide and Microgel Properties

   Författare :Ronja Widenbring; Martin Malmsten; Per Hansson; Catherine Picart; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Binding; Degradation; Enzyme; Gel; Hydrogel; Microgel; Peptide; Protein; Release; Pharmaceutical Physical Chemistry; Farmaceutisk fysikalisk kemi;

   Sammanfattning : Microgels are lightly cross-linked hydrogel particles in the sub-micrometer to micrometer size range with a capacity to drastically change their volume in response to changes in the external environment. Microgels have an ability to bind and store substances such as biomacromolecular drugs, notably proteins and peptides, and release them upon stimuli, making them potential candidates as drug delivery vehicles and functional biomaterials.

3. 2. Cell-penetrating peptides and bioactive cargoes : Strategies and mechanisms

   Författare :Kalle Kilk; Ülo Langel; Michael J. Gait; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell-penetrating peptide; delivery; Peptide nucleic acid; Biochemistry; Biokemi;

   Sammanfattning : The cell membrane is an impermeable barrier for most macromolecules. Recently discovered cell-penetrating peptides (CPPs) have gained lot of attention because they can cross the membrane, and even more, carry cargoes with them. How CPPs enter cells is still not clear, while the delivery of different cargoes has been convincingly shown. LÄS MER

4. 3. Antimicrobial activity of human seminal plasma and seminal plasma proteins

   Författare :Anneli Edström; Infektionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; semenogelin; antibacterial peptides; antifungal peptides; seminal plasma; antimicrobial peptides; vaginal pH; beta-microseminoprotein; peptides;

   Sammanfattning : Seminal plasma is semen without the spermatozoa. Human seminal plasma is a complex mixture of secretions from the sex accessory glands, mainly the seminal vesicles and the prostate. Seminal plasma has high protein content and it also contains ions, sugars and low molecular weight components. LÄS MER

5. 4. Interaction Between Microgels and Oppositely Charged Peptides

   Författare :Helena Bysell; Martin Malmsten; Per Hansson; Walter Richtering; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antimicrobial peptides; binding; cationic peptides; confocal microscopy; deswelling; distribution; electrostatic; homopolypeptides; microgels; peptides; release; swelling; PHARMACY; FARMACI; Pharmaceutical Physical Chemistry; farmaceutisk fysikalisk kemi;

   Sammanfattning : Lightly cross-linked polyelectrolyte microgels are materials with interesting properties for a range of applications. For instance, the volume of these particles can be drastically changed in response to pH, ionic strength, temperature, or the concentration of specific ions and metabolites. LÄS MER

7. 5. Tunable and modular assembly of polypeptides and polypeptide-hybrid biomaterials

   Författare :Christopher Aronsson; Daniel Aili; Karin Enander; Staffan Dånmark; Dennis Löwik; Linköpings universitet; []

   Sammanfattning : Biomaterials are materials that are specifically designed to be in contact with biological systems and have for a long time been used in medicine. Examples of biomaterials range from sophisticated prostheses used for replacing outworn body parts to ordinary contact lenses. Currently it is possible to create biomaterials that can e.g. LÄS MER
