16. Vectorization of oligonucleotides with cell-penetrating peptides : Characterization of uptake mechanisms and cytotoxicity
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
17. Specificity of antisense oligonucleotide derivatives and cellular delivery by cell-penetrating peptides
Sammanfattning : Atypical gene expression has a major influence on the disease profile of several severe human disorders. Oligonucleotide (ON) based therapeutics has opened an avenue for compensating deviant protein expression by acting on biologically important nucleic acids, mainly RNAs. LÄS MER
18. Internalization mechanisms of cell-penetrating peptides : Structure-activity relationships, cellular distribution and membrane toxicity studies
Sammanfattning : Transport of substances with pharmaceutical potential over the plasma membrane has been pushed a great step forward with the discovery of short cationic polypeptides, known as cell-penetrating peptides (CPP). Since then, the internalization mechanism and cargo delivery properties of CPPs has been extensively studied. LÄS MER
19. Proteolytic processing of the Alzheimer APP protein family during neuronal differentiation
Sammanfattning : Increased amyloid-β (Aβ) load in the brain, neurite degeneration, neuronal loss, and decreased levels of several neurotrophins are among the characteristics of Alzheimer’s disease (AD). Generation of Aβ occurs when the amyloid precursor protein (APP) is proteolytically processed by β- and γ-secretases in the amyloidogenic pathway. LÄS MER
20. Oxidative stress and alterations in the mammalian iron metabolism : A study on iron, inflammation, oxidative stress and neurodegeneration
Sammanfattning : Iron is essential for all living organisms, from bacteria to man for a broad variety of biological functions, including oxygen transport and DNA synthesis. However, iron can also be toxic, due to its involvement in the formation of highly reactive oxygen species through Fenton chemistry. LÄS MER
