2. 1. The release of histone proteins from cells via extracellular vesicles

   Author : Uma Muthukrishnan; Jonathan Gilthorpe; Miles Trupp; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Histone; extracellular vesicles; exosomes; extracellular histones extracellular DNA; cellular stress; proteomics; ESCRT complex; Lrrn1; mid-hindbrain organizer; ovarian cancer; ascites;

   Abstract : Histones are chromatin-associated proteins localized to the nucleus. However, extracellular histones are present in biofluids from healthy individuals and become elevated under disease conditions, such as neurodegeneration and cancer. READ MORE

4. 2. Isolation Strategies and Proteomic Characterization of Extracellular Vesicles

   Author : Aleksander Cvjetkovic; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Extracellular vesicles; Exosomes; Colorectal cancer; Proteomics;

   Abstract : “Extracellular vesicles” is the collective term used to describe vesicular entities that are released from cells into the extracellular environment. These vesicles are composed of a delineating lipid membrane and its cargo which can comprise of bioactive molecules such as lipids, RNA, DNA and proteins which can be shuttled between cells and thus function as a means of cell-to-cell communication.

5. 3. Cellular responses to amyloid-beta protofibrils : Focus on astrocytes, extracellular vesicles and antibody treatment

   Author : Elisabeth Nikitidou; Anna Erlandsson; Martin Ingelsson; Gunnar K. Gouras; Uppsala universitet; []
   Keywords : Alzheimer’s disease; Amyloid-beta; Protofibrils; Astrocytes; Extracellular vesicles; Antibody; Neurons; Degradation; Medicinsk vetenskap; Medical Science;

   Abstract : Knowledge about the cellular mechanisms behind the initiation and propagation of Alzheimer’s disease (AD) is limited. Decades of research have focused on neuronal abnormalities in AD, but recently more attention has been given to the glial cells. READ MORE

6. 4. Therapeutic potential of extracellular vesicles

   Author : Oscar Wiklander; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Extracellular vesicles (EVs) are nanometer-sized, lipid membrane enclosed, vesicles that are secreted by most, if not all, cells and contain macromolecular material of the source cell including lipids, proteins and various nucleic acid species. Over the last two decades, EVs have been recognized as important mediators of cell-to-cell communication that influence both physiological and pathological conditions. READ MORE

7. 5. Pancreatic extracellular communication. Applications to beta cell cultures and islet amyloid polypeptide aggregation

   Author : Diana Ribeiro; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; in vitro pancreatic models; induced pluripotent stem cells; stem cell differentiation; insulin; 3D-culture; extracellular vesicles; glucose-stimulated insulin secretion; islet amyloid polypeptide; type 2 diabetes mellitus; extracellular matrix; adipose-derived stem cells; Diabetes mellitus; protein aggregation;

   Abstract : Diabetes mellitus (DM) is a disease with epidemic proportions due to increased incidences worldwide, persistence of undiagnosed cases, uncontrolled forms of the disease, association with cardiovascular complications, and lack of definitive treatment options. In particular, type 2 DM (T2DM) is placing an enormous financial burden on worldwide healthcare systems that will increase in the futureThere is a need to develop physiological assay platforms that provide functionally relevant models of diabetes in order to accelerate the discovery of new treatments.
