2. 16. Studies on lipid transport and extracellular vesicle production in Caenorhabditis elegans ciliated neurons

   Author : Shapour Rahmani; Simon Tuck; Jonathan D. Gilthorpe; Anders Olsen; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; C. elegans; cilia; extracellular vesicles; tat; phospholipid translocase; P4-family ATPase;

   Abstract : The cilium is a protrusion of cell membrane. Both the protein and lipid contents of cilia are different from those of other parts of the cell membrane. While the transport of proteins into and out of cilia has been intensively studied, much less is known about how the lipid content of ciliary membranes is regulated. READ MORE

4. 17. Imaging and Spectroscopic Mapping of Blood Cell Activity : Nanoparticles and Neutrophil Extracellular Traps

   Author : Kalle Bunnfors; Kajsa Uvdal; Caroline Brommesson; Christelle Prinz; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Neutrophils; Neutrophil extracellular traps; fluorescence; XPS; TEM;

   Abstract : Imaging and visualization of cell activity when exposed to nanomaterial are of main importance, when investigating biological response to a wide range of biomaterials from medical implants to smart nanoprobes. The ability to provide molecular and chemical information with spatial resolution in the region of sub-µm leads to increased insight and understanding of these biological challenges. READ MORE

5. 18. Epigenetic influence on cardiovascular protective mechanisms in vivo: explorations of t-PA release and extracellular vesicle genetic content

   Author : Kristina Svennerholm; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; myocardial ischemia; epigenetics; histone deactylase inhibition; t-PA; extracellular vesicles; ischemic preconditioning;

   Abstract : ABSTRACT Background: Ischemic heart disease is one of the leading causes of death globally. This thesis explores endogenous mechanisms protecting against myocardial ischemia in context of epigenetics (changes in gene activity not caused by changes in DNA sequences). READ MORE

6. 19. Roles of membrane vesicles in bacterial pathogenesis

   Author : Svitlana Vdovikova; Sun Nyunt Wai; Richard Lundmark; Ann-Beth Jonsson; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Membrane vesicles; autophagy; pore-forming toxin; pore formation; Listeria monocytogenes; Vibrio cholerae; virulence factor; PrtV protease; listeriolysin O; V. cholerae cytolysin; mikrobiologi; Microbiology; molekylärbiologi; Molecular Biology;

   Abstract : The production of membranous vesicles is observed to occur among organisms from all domains of the tree of life spanning prokaryotes (bacteria, archaea) and eukaryotes (plants, animals and fungi). Bacterial release of membrane-derived vesicles (MVs) has been studied most extensively in cases of Gram-negative species and implicating their outer membrane in formation of extracellular MVs.

7. 20. Signaling to the immature brain - Choroid plexus, insulin-like growth factor 1 and extracellular vesicles

   Author : Niklas Ortenlöf; Lund Pediatrik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; IGF-1; Choroid plexus; Immature brain; Extracellular vesicle; CSF; Preterm infants;

   Abstract : Extremely preterm infants (i.e., born below 28 gestational weeks), are at high risk of developing brain morbidities including intraventricular hemorrhage (IVH) and neurodevelopmental impairment. Despite over 50 years of research, there is currently no effective therapy available for preventing IVH. READ MORE
