1. 11. Regulation of GRAF1 membrane sculpting function during cell movement

   Författare :Monika K. Francis; Richard Lundmark; Pekka Lappalainen; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endocytosis; migration; polarisation; tension; CLIC GEEC; GRAF1; Rho GTPase; Cdc42; Rab8; medicinsk biokemi; Medical Biochemistry;

   Sammanfattning : All eukaryotic cells rely on endocytic events to satisfy a constant need for nutrient and fluid uptake from their surroundings. Endocytosis-dependent turnover of cell surface constituents also serves to control signal transduction and establish morphological changes in response to extracellular stimuli. LÄS MER

3. 12. Vectorization of oligonucleotides with cell-penetrating peptides : Characterization of uptake mechanisms and cytotoxicity

   Författare :Samir EL Andaloussi; Ülo Langel; Alain Prochiantz; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CPP; endocytosis; splice correction; siRNA; PNA; cargo delivery; M918; Neurochemistry; Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

   Sammanfattning : The hydrophobic plasma membrane constitutes an indispensable barrier for cells in living animals. Albeit being pivotal for the maintenance of cells, the inability to cross the plasma membrane is still one of the major obstacles to overcome in order to progress current drug development. LÄS MER

4. 13. Mechanistic studies on the role of extracellular vesicles in the tumor microenvironment

   Författare :Helena Christianson; Tumörmikromiljö; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microvesicle; exosome; Key words Extracellular vesicle; glioblastoma; hypoxia; angiogenesis; acidosis; proteoglycan; endocytosis; carbonic anhydrase IX; biomarker.;

   Sammanfattning : The transition from normal into malignant cells with acquired uncontrolled growth is a process where cancer cells viciously develop adaptive strategies to overcome microenvironmental and metabolic stress. Hypoxia, or deficient oxygen supply, is a common feature of the expanding tumor which alters cell metabolism and consecutively causes lowered intracellular pH. LÄS MER

5. 14. Novel actions of thrombin-derived host defense peptides

   Författare :Finja Hansen; Lund Dermatologi och venereologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Host defense peptides; Thrombin; Monocytes Macrophages; Gram-negative bacteria; LPS; TLR; Phagocytosis; Inflammation; Endocytosis;

   Sammanfattning : Thrombin-derived C-terminal peptides (TCPs) constitute a novel class of immunomodulatory host defense peptides, generated during infection and inflammation. Previous investigations have shown that TCPs of 2-3 kDa inhibit pro-inflammatory immune responses in vitro and in vivo, but their mode of action remained unclear. LÄS MER

7. 15. Adaptive mechanisms in the hypoxic tumor microenvironment. Functional role of proteoglycans and identification of potential treatment targets

   Författare :Julien Menard; Tumörmikromiljö; []
   Nyckelord :Hypoxia; Acidosis; Proteoglycans; Endocytosis; Glioblastoma; Lipid; Caveolin-1; Antibody-drug conjugate;

   Sammanfattning : Cancer cells reside in a complex microenvironment comprising stromal cells and immune cells embedded in an extracellular matrix (ECM). Early on in tumor progression, cells reach a critical volume beyond which blood supply is impaired, leading to a decrease in oxygen levels (hypoxia) and nutrient supply. LÄS MER
